The TDK Group is constantly developing new products that derive theirstrength from our original technology and know-how.
Because our output is mostly electronic components, the end-user
rarely encounters our products directly, but they are at the core ofwhat makes many set products function. By extension, the set products
embody our vision for the future.
A few examples are shown below, highlighting sophisticatedtechnology for effective use of energy and for a new generation ofenvironment-conscious products.

DC Electrification
Eco Home
Normally, electrical power is supplied toresidential homes in the form of AC(alternating current) by power companies orother providers. However, because manyelectrical appliances actually run on DC(direct current), AC adapters are needed toconvert the alternating current into direct
current. In the DC electrification eco homeon the other hand, power is distributed as
direct current. Power obtained from naturalenergy sources is stored in lithium-ion
batteries, eliminating the need for theconversion stage with its inherent losses.
Consequently, energy can be used more
efficiently, which helps to reduce CO 2emissions.

Soft Magnetic Metal
Material for Generatorsand Motors
Utilized in generators andmotors in wind power
installations that turn windenergy into electricalenergy.

DC-DC Converter
Used in PCUs (Power Control Units)of hybrid electric vehicles to turnthe high voltage from the batteries
into the lower voltage required todrive the electronic equipment ofthe automobile. Featuring highconversion efficiency as well ascompact dimensions and low
weight, these TDK products
contribute to better fuel economy.

Dye-SensitizedSolar Cells
Used in solar power
generation that turn solar
energy into electricalenergy, for greatly reduced
CO2 emission levels.

Battery Current Sensor
Designed for detecting input andoutput current levels in battery
systems, so that overcharging andexcessive discharging can bereliably prevented. This protection
contributes to longer battery life.
Accurate detection of remaining
battery capacity is anotherimportant aspect for precise system
control, which contributes tobetter fuel economy.

Hybrid Electric Vehicle
Automobile that uses both anelectric motor and a combustion
engine to achieve much better
fuel economy than a conventional
automobile. Exhaust gas iscleaner, with significantly lower
CO2 emissions. This type of vehicle
is currently attracting a lot ofattention because of its overalllower environmental load.

High-Performance Neodymium
Magnet NEOREC 53 Series
Proprietary TDK technology has
made it possible to build magnets
with drastically improved
magnetism. These are used in theelectric motors of hybrid electricvehicles, providing assistive power
to the engine and enabling therecycling of energy. The magnets
have excellent heat resistancecharacteristics, which prevent a
drop in motor output power at hightemperatures, thereby contributing
to better fuel economy.

TDK ʼ s Environment- Conscious Produc ts Line -up
SUPERECO LOVEproducts

Changes in environment- conscious design of chip components
1990

The Eco Love symbol is meant to indicate that aproduct is based on love for our global environment. Its
design expresses our stance, awareness, and concern
for environmental issues.
The logo is used widely, both for company-internal
communications related to our drive for creating

environment-conscious products and in promotional
material aimed at third parties. It serves to identify
environment-conscious products that have special
merits, and is found in catalogs, on our web site, and inother locations.
We intend to further increase the ratio of “EcoLove” and “Super Eco Love” products in our overall
output in future. Together with our customers, wewant to help protect the earth and achieve sustainable
progress.
