The B57238S0220M000 is a leaded and coated NTC thermistor from TDK Electronics designed for inrush current limiting applications. It offers a nominal resistance of 22 Ω at 25°C with a tolerance of ±20%. The device is rated for a maximum current of 4 A and a maximum power dissipation of 3.9 W at 25°C. It features a dissipation factor of 20 mW/K and a thermal time constant of 80 seconds.
The operating temperature range is -55°C to 170°C, based on its climatic category 55/170/21 per IEC 60068-1. The component is flame retardant to UL 94 V-0 and holds UL approval (file E338926) as well as IEC, VDE, and CQC certifications.
The mechanical dimensions include a diameter of 16 mm, body thickness 6 mm, body height 23 mm, and lead spacing of 7.5 mm with kinked tinned copper wire leads. Typical applications include inrush current limiting in switch-mode power supplies and soft-start motors. The standard delivery mode is bulk, with optional cardboard tape on reel or ammo pack packaging.
