*1 : NTC thermistor is measured at 25°C in still air, as a single unit without mounting.
*2 : Permissive Operating Current raises NTC thermistor’s temperature by 1°C.
The current less than 1/10 of the Permissive Operating Current value is recommended
in order to prevent self heating of the NTC thermistor.
*3 : When Rated Electric Power (100mW) is applied to NTC thermistor at 25°C in still air,
NTC thermistor’s temperature rises by approx.100°C.

3. Solder and Flux
(1) Solder Paste
i. Flow Soldering : We are using the following solder paste for any internal tests of this product.
• Sn:Pb=63wt%:37wt%
• Sn:Ag:Cu=96.5wt%:3.0wt%:0.5wt%
ii. Reflow Soldering : 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 Metals Industry Co., Ltd.)
(2) Flux : Use rosin type flux in soldering process. If below flux is used, some problems might be
caused in the product characteristics and reliability. Please do not use below flux.
• Strong acidic flux (with halide content exceeding 0.1wt%).
• Water-soluble flux(*Water-soluble flux can be defined as non rosin type flux including
wash-type flux and non-wash-type flux.)
4. For removing the flux after soldering, observe the following points in order to avoid
deterioration of the characteristics or any change of the outer electrodes quality.
(1) Cleaning Conditions
Solvent Dipping Cleaning Ultrasonic Cleaning
Less than 5 min.
Less than 1 min.
at room temp.
Isopropyl 20W/L
or
Alcohol Frequency of several 10 KHz
Less than 2 min.
to several 100 KHz.
at 40°C max.
• Please keep mounted parts and a substrate from an occurance of resonace in ultrasonic cleaning.
• Please do not clean the products in the case of using a non-washed type flux.
(2) Drying : Please fully perform cleaning and keep flux and cleaner components from remaining.
After cleaning, dry promptly this product.
5. Do not give this product a strong press-force nor a mechanical shock. Because such
mechanical forces may cause cracking or chipping of this ceramic product.
6. In your mounting process, observe the following points in order to avoid deterioration of the
characteristics or destruction of this product. The mounting quality of this product may also
be affected by the mounting conditions, shown the points below.
(1) Please mount this product by soldering. When mounted by other methods, such as conductive
adhesives,please contact us in advance.
(2) Recommendable Land Size
Too big land size gives too much solder paste on the land. It may cause destruction of
this product, because of the mechanical stress especially in the case of board bending.

- (4) Adhesive Application and Curing
- i. If insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, this product may have a loose contact with the land, during flow soldering.
- ii. Too low viscosity of adhesive causes this product to slip on broad, after mounting.
- (5) Allowable Soldering Temperature and Time
**==> picture [583 x 654] intentionally omitted <==**
**----- Start of picture text -----**
i. Solder within the temperature and time combinations, indicated by the slanted lines
in the following graphs.
ii. The excessive soldering conditions may cause dissolution of metallization or
deterioration of solder-wetting on the outer electrode.
iii. In case of repeated soldering, the total accumulated soldering time should be within the range
shown below figure. (For example, Reflow peak temperature : 260°C, twice → The total
accumulated soldering time at 260°C is within 30sec.)
