B57464S 400M S464/40/M Storage Store thermistors only in original packaging. Do not open the package before storage. Storage conditions in original packaging storage temperature -25 °C +45 °C, relative humidity 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 SOx, Cl etc . Solder thermistors after shipment from EPCOS within the time specified: - Leaded components 24 months 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. Low-ohmic 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 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.

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. 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 adjacent components are placed at a sufficient distance from the thermistor to allow for proper cooling of the NTC inrush current limiters. Ensure that adjacent materials are designed for operation at temperatures comparable to the surface temperature of the thermistor. Be sure that surrounding parts and materials can withstand this temperature. Make sure that inrush current limiters are adequately ventilated to avoid overheating. Avoid contamination of thermistor surface during processing. Operation
