NTC Thermistors
for Temperature Compensation 0603 (1608) Size

0.8±0.15

0201/0402/0603/0805 sized Chip NTC Thermistors have Nibarrier termination and provide excellent
solderability and offer high stability in environment
by unique inner construction.
0.2—0.6■ Features
1. Excellent solderability and high stability inenvironment
2. Excellent long time aging stability
3. High accuracy in resistance and B-constant
4. Flow/Reflow soldering possible
5. Same B-constant in the same resistance in the threesizes (0805/0603/0402)
Easy to use smaller size in the circuits
6. Lead is not contained in the product7. NCP15/18/21 series are recognized by UL(UL1434, File No. E137188 Vol. 2, Sec. 2)

4. Solder and Flux
(1) Solder and Paste(a) Reflow Soldering : NCP03/15/18/21 Series
Use RA/RMA type or equivalent type of solder paste. For
your reference, we are using the solder paste below for
any internal tests of this product.
•RMA9086 90-4-M20 (Sn:Pb=63wt%:37wt%)(Manufactured by Alpha Metals Japan Ltd.)•M705-221BM5-42-11 (Sn:Ag:Cu=96.5wt%:3.0wt%:0.5wt%)(Manufactured by Senju Metal Industry Co., Ltd.)(b) Flow Soldering : NCP18/21 Series
We are using the solder paste below. For any internal
tests of this product.
•Sn : Pb=63wt%:37wt%•Sn : Ag : Cu=96.5wt% : 3.0wt% : 0.5wt%(2) Flux
Use Rosin-based flux.
Do not use strong acidic flux (with halide content
exceeding 0.2wt%)

5. Cleaning Conditions
For removing the flux after soldering, observe the following
points in order to avoid deterioration of the characteristics orany change of the external electrodes' quality.

1. High-accuracy of +-1%+-1% of resistance and B-Constant tolerance isrealized due to uniform thickness by the precise
sheet forming method.
2. Quick response
This product provides faster response time due
to its smaller size.
3. Taping type is available (Standard type).
4. Strong lead strength
Original lead-wiring technique assures reliable
connection. It can be formed and bent flexibly
according to the mounting conditions.

for Temperature Sensor Lead Type/Lead Insulation Type !Caution/Notice■ !Caution (Storage and Operating Conditions)This product is designed for application in an
ordinary environment (normal room temperature,humidity and atmospheric pressure).
Do not use under the following conditions because allthese factors can deteriorate the productcharacteristics or cause failures and burn-out.
1. Corrosive gas or deoxidizing gas(Chlorine gas, Hydrogen sulfide gas, Ammonia gas,
Sulfuric acid gas, Nitric oxide gas, etc.)

2. Volatile or flammable gas
3. Dusty conditions
4. Under high or low pressure
5. Wet or humid locations
6. Places with salt water, oils, chemical liquids ororganic solvents
7. Strong vibrations
8. Other places where similar hazardous conditions
exist■ !Caution (Others)
Be sure to provide an appropriate fail-safe function
on your product to prevent secondary damages that may
be caused by the abnormal function or the failure of
our product.

■ Notice (Storage and Operating Conditions)To keep solderability of product from declining, thefollowing storage condition is recommended.
1. Storage condition:
Temperature -10 to +40 degree C
Humidity less than 75%RH (not dewing condition)
2. Storage term:
Use this product within 6 months after delivery by
first-in and first-out stocking system.

3. Handling after unpacking:After unpacking, reseal product promptly or store
it in a sealed container with a drying agent.
4. Storage place:
Do not store this product in corrosive gas(sulfuric acid gas, chlorine gas, etc.) or in
direct sunlight.

6■ Notice (Rating)
Use this product within the specified temperature
range.
Higher temperature may cause deterioration of thecharacteristics or the material quality of thisproduct.

■ Notice (Soldering and Mounting)■ Notice (Handling)

1. Be sure that the preheat-up does not melt thesoldering of this product. Excessive heat may
cause failure to open, short or insulation breakdown.
2. Do not touch the body with soldering iron.
The soldering point should be min. 5mm away fromthe root of lead wire.

1. The ceramic element of this product is fragile, andcare must be taken not to load an excessive
press-force or not to give a shock at handling.
Such forces may cause cracking or chipping.
2. Do not apply an excessive force to the lead.
Otherwise, it may cause junction between lead andelement to break or crack. Holding element by side
lead wire is recommended when lead wire is bent or
cut.

This product effectively supresses surge currents
which are generated when switching power regulators
are turned on.

■ Features

Coating Extension
on Lead : to line A

1. Lead is not contained in the ceramic element, theterminations, the solder for inner connection andthe coating resin.
2. Most suitable for power supplies of less than 100W
3. Excellent recovery characteristics due to resin
coating with excellent heat characteristics
4. Highly reliable

for Inrush Current Suppression Lead Type !Caution/Notice■ !Caution (Storage and Operating Conditions)
1. This product is designed for the Switching Power
Supply with smoothing capacitors.
Other applications of this product may result infire.
2. Use this product within the specified maximum
current. Otherwise it may catch fire in the worst
case.
3. Use this product with smoothing capacitor within
the specified maximum capacitance value. Otherwise
it may catch fire in the worst case.
4. This product is designed for application in an
ordinary environment (normal room temperature,humidity and atmospheric pressure).
Do not use under the following conditions because

all these factors can deteriorate theproduct characteristics cause failure and burn-out.
(1) Corrosive gas or deoxidizing gas.
(Chlorine gas, Hydrogen sulfide gas, Ammoniagas, Sulfuric acid gas, Nitric oxide gas, etc.)(2) Volatile or flammable gas(3) Dusty conditions(4) Under high or low pressure(5) Wet or humid conditions(6) Near with salt water, oils, chemical liquids ororganic solvents(7) Strong vibrations(8) Other places where similar hazardous conditions
exist.

■ !Caution (Others)
Be sure to provide an appropriate fail-safe function
on your product to prevent secondary damages that may
be caused by the abnormal function or the failure of
our product.

■ Notice (Storage and Operating Conditions)To keep solderability of product from declining, thefollowing storage condition is recommended.
1. Storage condition:
Temperature -10 to +40 degree C
Humidity less than 75%RH (not dewing condition)
2. Storage term:
Use this product within 6 months after delivery by
first-in and first-out stocking system.

3. Handling after unpacking:After unpacking, reseal product promptly or store
it in a sealed container with a drying agent.
4. Storage place:
Do not store this product in corrosive gas(sulfuric acid gas, chlorine gas, etc.) or in
direct sunlight.

■ Notice (Rating)

7

Use this product within the specified temperature
range.
Higher temperature may cause deterioration of thecharacteristics or the material quality of thisproduct.

■ Notice (Soldering and Mounting)
1. Be sure that the preheat-up does not melt thesoldering of this product. Excessive heat may
cause failure to open, short or insulation breakdown.
2. Do not touch the body with soldering iron.
The soldering point should be min. 5mm away fromthe root of lead wire.

for Inrush Current Suppression Lead Type !Caution/Notice■ Notice (Handling)
1. When this product is operated, temperature of somearea may be about 160 (degree C).
Use proper surrounding parts and material whichwithstand such temperature. If they are inadequate
and kept at high temperature for long time, they
may be deteriorated or may produce harmful gas.
And, such harmful gas may deteriorate the elementof this product.
2. This product does not have waterproof construction.
Splashed water may cause failure mode such asdeterioration of characteristics or current leak.
So, do not apply cleaning to immerse it into wateror any solvent.

■ Notice (Others)
1. This products need sufficient cool off time torecover high resistance. Repeated ON-OFF may cause
over specified current rating.
Make sure inrush current do not exceed thespecified ratings even at the worst condition.
(maximum ambient temperature and the shortest off
time.)
2. The resin coating of this product does notguarantee insulating. Keep an adequate insulating
distance to surrounding parts.

736

3. The ceramic element of this product is fragile, andcare must be taken not to load an excessive
press-force or not to give a shock at handling.
Such forces may cause cracking or chipping to theelement.
4. Do not apply an excessive force to the lead wire.
Otherwise, it may cause break off junction between
lead wire and element, or may crack element.
So, fix lead wire of element side when lead wireis bent or cut.
