B57235S0509M051 Description

Short technical summary and product information.

The B57235S0509M051 is a leaded NTC thermistor designed for inrush current limiting applications such as switch-mode power supplies and soft-start motors. It features a nominal resistance of 5 Ohms at 25°C with ±20% tolerance and a maximum current rating of 4.2A over 0 to 65°C. The component dissipates up to 1.8W at 25°C with a dissipation factor of 9 mW/K in air. Its operating temperature range spans -55°C to +170°C, meeting climatic category 55/170/21 per IEC 60068-1. The radial leaded disc package has a maximum diameter of 9.5mm, thickness of 6.0mm, and height of 14.0mm. Lead spacing is 5.0mm nominal, with lead diameter of 0.6mm and minimum lead length 25.0mm. The coating material is flame retardant to UL 94 V-0. This ICL is approved by CQC, UL, and VDE. Delivery is in reel pack (ordering code suffix 51).
