                                                                                                  The B57045K0473K000 is an NTC Thermistor with electrically isolated aluminium case, tinned copper leads and screw terminals. This B57045K series thermistor features good thermal coupling through screw-type case (thread M3). 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 temperature compensation, measurement and control (chassis mounting).
