                                                                                                    The B57703M0502G040 is a 2-pin NTC Thermistor encapsulated in metal-tag case, with 30AWG PTFE-insulated leads of silver-plated nickel wire or 26AWG (stranded, 7 x 34AWG), PTFE-insulated leads of silver-plated copper wire. This B57703M series through hole mounting thermistor features good thermal coupling through metal tag. 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. 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 surface temperature measurement (e.g. on housings and heat sinks).

Avoid contamination of thermistor surface during storage, handling and processing. Do not touch components with bare hands.
