Environmental Protection Activities ReportCreation of Environmental Measures in Products
The FDK Group is committed to developing and oﬀering of eco-friendly products by paying eﬀorts toeliminate hazardous chemical substances and reduce energy and resource consumption from the entire
lifecycle of a product from development to disposal.

The FDK Group conducts a Product Environmental Assessment to understand how a product is friendly to the environment. In the Third
Environmental Action Plan, the conventional concept of eco-friendly products and green products (eco-friendly reinforced product) was
further reinforced, and development and provision of super-green products with top environmental elements were promoted.

Activities Report

In FY2006, 8 themes were set to develop super-green products.
As a result, RF multilayer chip inductors AML0603E Series wererecognized as super-green products. Compared with other inductors,
the Q-value is raised and hence, the electricity consumption under thehigh-frequency band is less by 20% to 30% than that of the conventional ones. The energy-saving performance is among the highest in
the world. The RF multilayer chip inductors are the Group s second
super-green products following to an ultra small multilayer power
inductor MIPF 2520D Series produced in FY2005.

Whether a product contains the top environmental elements or not, which is tosay whether it is the world s smallest or the world s ﬁrst product, is determined
as of when the product is ﬁrst released to the market.

Production of Environmental Measures on Products

Major Eco-Friendly Products Developed in FY2006
RF Multilayer Chip Inductor AML0603E Series

Application
It is used as a part of, forexample, a choke circuit for
power line and an impedance
matching circuit of signallines for cellular phones andvarious high-frequency
modules.

Features

Comment from the implementer

While suppressing the surge of direct current resistance to aminimum possible level, the Q factor is raised to 22 to 23, whichis the world highest. Compared to the conventional products,
the Q factor under high-frequency band has risen by 20 to 30%.
In order to respond to the requirement of diversiﬁed application of the product, 20 types of inductors are available with
the inductance value ranged from 2 to 12 nH.

How to suppress direct current resistance
while raising the Q factor under the highfrequency band environment was the key todevelop this product. Raising the Q factor
makes the energy loss smaller and cancontribute to saving electricity consumption.
It is expected that more high functional but
smaller in size cellular phones will appear in
the future, and the demand for energy saving
will be heightened. I am determined tocontinue development of eco-friendly productsthat match to the diversiﬁed requirementsof the society.

Eco-Friendliness
Because the Q factor reached to the world highest level, theelectricity consumption was successfully reduced to 20 to
30% for use under the high-frequency band, compared toconventional products. No lead is used in the inductors andhence they are European RoHS compliant. Due to having theworld highest energy-saving performance, the products arerecognized as super-green products by the Fujitsu Group.

wireless communication system that is
capable of reaching to a remote place andhigh-speed mobile communication. I am
expecting that the market for this productwill expand in the future.

Eco-Friendliness
The world smallest and world thinnest baluns can contributeto minimizing consumption of resources in manufacturing them.
The low insertion loss, among the highest in this class also
contributes to electricity saving. The product is European
RoHS compliant.

Features

Comment from the implementer

Utilizing our unique technologies of accurate shape design ofyokes (thin sheet plate formed by drawing), designing coils
and magnetic circuits, the stepper motor realized higher
output by approx. 20% compared to a conventional motor of
the same size. This stepper motor will pave the way forsmall-in-size, light-in-weight and electricity-saving performance of devices that the stepper motor is incorporated.

While remaining the size and the appearance of this stepper motor the same as thatof conventional products, this product realizes
higher output performance due to the merger
and arrangement of our technologies
cultivated so far. Raising output level can
reduce electricity consumption. Due to the
product s high output level, it can contributeto decrease the volume of CO2 emission
causing of global warming. It is expectedthat use of chemical substances will beseverely controlled and restricted. We
are determined ourselves to develop ecofriendly and highly eﬃcient small motors.

Eco-FriendlinessElectricity saving of approx. 20% is realized in this productcompared to conventional ones (measured under the testing
condition of the FDK Group, i.e. voltage between the twoterminals as 2.9V and coil resistance as 20Ω under the twophase excitation of 1,500pps). Solder used for the coilterminal to connect ultra-thin magnet wires is lead-free, andhence, the product is European RoHS compliant.

Blu-ray disc and to drive
lenses for autofocusing andzooming.

Comment from the implementerWith the ongoing process of small-in-sizeand high-functional portable devices, amotor used to drive a camera lens also
needs to be more small in size, moreaccurate, stronger in torque and highly
energy saving. This year, we were successful
in developing a small-in-size motor meetingthese requirements using a special strong
magnet and optimized magnetic circuits
and other methods unique to us. In orderto save the limited global resources, wewill address development of more small
and more light motors.

Elements for Ultrasonic Motors
Features

Comment from the implementer

Compared to an ordinary electrically driven motor, an ultrasonicmotor works faster and smoother, has higher torque and emits
lesser noises. This product is used as an element for driving
an ultrasonic motor and realizes signiﬁcantly smaller in sizeand higher torque in high and low speed ranges.

As a digital camera is being widely used,a smooth and high speed autofocusing
function conventionally used for highend cameras is now gradually spread to
low-end models. Under such a circumstance, the market requires more smallin-size and high torque products. We weresuccessful in developing a manufacturing method suitable for making thinnerproducts and as a result, a signiﬁcantly
small-in-size and high torque product has
been successfully launched.

Application
It is used as a lens actuatorof autofocusing system used
in a camera.

Approaches to Totally Eliminate Hazardous Substances in Products
The FDK Group has been working for establishing a management system that ensures eliminating use of hazardous substances in its
products, in order to comply with the EU RoHS Directive. In October 2004, the Committee for Products Containing Hazardous Chemical
Substances was set up and is in operation in order to totally eliminate using hazardous chemical substances included in the products.

Targets of the Third Environmental Action Plan

To eliminate the use of hazardous substances designated by Fujitsu Group in manufacturing products by the end of FY 2005, except for those designated by RoHS whose elimination target is theend of December 2004
■Use of hazardous substances listed in 31 categories of Fujitsu Group s list will be totally eliminated by the end of FY 2005.
■For products shipped to Europe and covered under the RoHS Directive, use of lead, cadmium, mercury, hexavalent chromium
compounds, PBB and PBDE will be totally eliminated by the end of December 2004.

Elimination of Hazardous Chemical
Substances and Confirmation Activities
In FY2005, all hazardous substances designated by Fujitsu Group
were completely eliminated from the products manufactured by
FDK. As to the chemical substances whose elimination was requiredby the RoHS Directives for all products shipped to customers, or
which are to be shipped to Europe were successfully eliminated as
per the request of our customers. For other prohibited chemical
substances for which alternative items were not available and forwhich our customers requested us to continue searching, we
followed customer speciﬁcations in dealing with the issue.
The progress of complying with the RoHS Directive has been
uploaded to the FDK website and made accessible to our customers as well as our employees, since FY2005. The website lists
RoHS compliant products as well as those items not to be compliedwith the Directive. Critical substances relating to the RoHS are
examined in-house using an X-ray ﬂuorescent spectrometer and
ICP analysis.

Control Process for Banned Substances

Establishment of a System to Control
Hazardous Chemical Substances
With the idea that any product containing hazardous substances isa defect, the FDK Group has been operating a hazardous chemical
substances control system, set up at all of its production sites, as apart of its quality assurance system (ISO9001 compliant) since
FY2005.
In FY2006, an audit on the hazardous chemical substances control
system was made by members of the Committee for ProductsContaining Hazardous Chemical Substances. The audit s purpose
was to conﬁrm a system of avoiding inclusion of hazardous chemical substances in products, as well as how that system wasmaintained, as objectively as possible, in order to extract andremedy problems found, if any.
After extracting problems and measures taken, in December 2006,
a system capable of controlling hazardous chemical substances astargeted was established at all of FDK s production sites. An
X-ray ﬂuorescent spectrometer was newly introduced to 2
overseas sites in FY2006. Now 6 major sites in total, in and out ofJapan, use a spectrometer. Due to the introduction of the unit,
acceptance tests and process controls can now be smoothly
operated at each site.
