Cautions and warnings
See "Important notes" of this data sheet.
Storage
Store thermistors only in original packaging. Do not open the package before storage. Storage conditions in original packaging: storage temperature -25 °C to +45 °C, relative
humidity ≤75% annual mean, maximum 95%, dew precipitation is inadmissible.
Avoid contamination of thermistors surface during storage, handling and processing. Avoid storage of thermistor in harmful environments like corrosive gases (SO Solder thermistors after shipment from TDK Electronics within the time specified:
- Leaded components: 24 months
, Cl etc).
x
Handling
NTC inrush current limiters must not be dropped. Chip-offs must not be caused during
handling of NTC inrush current limiters.
Components must not be touched with bare hands. Gloves are recommended. Avoid contamination of thermistor surface during handling. In case of exposure of the NTC inrush current limiters to water, electrolytes or other aggressive
media, these media can penetrate the coating and reach the surface of the ceramic. Low­ohmic or high-ohmic behavior may occur due to the formation of an electrolyte with metals (silver/lead/tin from metallization or solder). Low-ohmic behavior is caused by electrochemical migration, high-ohmic behavior by dissolving of the electrode. In either case, the functionality of the NTC inrush current limiters can not be assured.
Washing processes may damage the product due to the possible static or cyclic mechanical
loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts, which might lead to reduced reliability or lifetime.
Bending / twisting leads
A lead (wire) may be bent at a minimum distance of twice the wire’s diameter plus 4 mm from
the component head or housing. When bending ensure the wire is mechanically relieved at the component head or housing. The bending radius should be at least 0.75 mm.
Twisting (torsion) by 180°of a lead bent by 90° is permissible at 6 mm from the bottom of the
thermistor body.
Soldering
Use resin-type flux or non-activated flux. Insufficient preheating may cause ceramic cracks. Rapid cooling by dipping in solvent is not recommended. Complete removal of flux is recommended.

Mounting
The varying representations of the ordering codes are due to
Inrush Current Limiters (ICLs) P27/**/M301
When thermistors are sealed, potted or over-molded, there must be no mechanical stress
Electrode must not be scratched before/during/after the mounting process. Contacts and housings used for assembly with thermistor have to be clean before mounting. During operation, the inrush current limiters surface temperature can be very high. Ensure that
Ensure that adjacent materials are designed for operation at temperatures comparable to the

caused by thermal expansion during the production process (curing/ over-molding process) and during later operation. The upper category temperature of the thermistor must not be exceeded. Ensure that the materials used (sealing / potting compound and plastic material) are chemically neutral.
adjacent components are placed at a sufficient distance from the thermistor to allow for proper cooling of the NTC inrush current limiters.
surface temperature of the thermistor. Be sure that surrounding parts and materials can withstand this temperature.
Operation
Use NTC inrush current limiters only within the specified operating temperature range. Use NTC inrush current limiters only within the specified voltage and current ranges. Environmental conditions must not harm the NTC inrush current limiters. Use NTC inrush
current limiters only in normal atmospheric conditions.
Contact of NTC inrush current limiters with any liquids and solvents should be prevented. It
must be ensured that no water enters the NTC inrush current limiters (e.g. through plug
terminals). For measurement purposes (checking the specified resistance vs. temperature),
the component must not be immersed in water but in suitable liquids (e.g. Galden).
In case of exposure of the NTC inrush current limiters to water, electrolytes or other aggressive
media, these media can penetrate the coating and reach the surface of the ceramic. Low­ohmic or high-ohmic behavior may occur due to the formation of an electrolyte with metals (silver/lead/tin from metallization or solder). Low-ohmic behavior is caused by electrochemical migration, high-ohmic behavior by dissolving of the electrode. In either case, the functionality of the NTC inrush current limiters can not be assured.
Be sure to provide an appropriate fail-safe function to prevent secondary product damage
caused by malfunction (e.g. use a metal oxide varistor for limitation of overvoltage condition).

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule we are either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether a product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or failure
before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high
level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or life­saving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useful information on this will be found in our Material
Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have any more detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms and Conditions of Supply.
7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard.
The IATF certifications confirm our compliance with requirements regarding the quality
management system in the automotive industry. Referring to customer requirements and customer specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting
individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral
requirements, we hereby like to emphasize that only requirements mutually agreed upon can and will be implemented in our Quality Management System. For clarification purposes we like
to point out that obligations from IATF 16949 shall only become legally binding if individually agreed
upon.
