EPCOS B57238S0509M000 热敏电阻, NTC, 5R, 4.4A
The is a 2-pin NTC Thermistor with kinked leads of tinned copper wire and coated thermistor disk for line applications. This B57238S0 series thermistor is useable in series connections up to 265Vrms. It is marked with manufacturer"s logo, NTC and resistance value stamped on. A lead wire may be bent at a minimum distance of twice the wire"s diameter plus 4mm 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 0.75mm. Twisting torsion by 180° of a lead bent by 90° is permissible at 6mm from the bottom of the thermistor body. Soldering can use resin-type flux or non-activated flux. The soldering due to insufficient preheating may cause ceramic cracks. Suitable for inrush current limiting, switch-mode power supplies and soft-start motors e.g. in vacuum cleaners.

Avoid contamination of thermistors surface during storage, handling and processing. Do not touch components with bare hands. Washing process may damage due to possible static/cyclic mechanical loads.
The self-heating of a thermistor during operation depends on the load applied and the applicable dissipation factor. Gloves are recommended.
