Product Overview

The B57211P0409M301 is a 2-pin NTC Thermistor with kinked leads of tinned copper wire and black coated thermistor disk. This B57211P0 series thermistor 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 and peripheral communication equipment.
  • 7.5mm Lead spacing
  • High stability of electrical characteristic
  • Bending radius should be at least 0.75mm
  • 3W Maximum power
  • UL94V-0 Flammability rating
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.
