B57236S0250M000

Overview

The B57236S0250M000 is a leaded NTC thermistor from the B57236S0 series manufactured by EPCOS (TDK). It features a coated disk package with radial tinned copper leads for through-hole mounting. The component has a nominal resistance of 25 ohms at 25 °C with a tolerance of ±20%. It supports a maximum rated AC voltage of 265 V and a power dissipation of 2.1 W. The operating temperature range spans from -55 °C to +170 °C, with a thermal time constant of approximately 70 seconds.

Feature Summary

• Coated thermistor disk construction for environmental protection
• Capable of use in series connections up to 265 VRMS
• Radial leads made of tinned copper wire

Applications

• Inrush current limiting
• Surge current suppression
• Temperature compensation

Procurement Notes

Verify that the specific part number matches the required resistance value and tolerance. Confirm compliance with RoHS and lead-free standards if applicable to your assembly process. Ensure the physical dimensions and lead spacing are compatible with the target PCB layout or wiring harness requirements before finalizing procurement.

Selection Notes

Select this component when a robust, high-power NTC thermistor is needed for industrial or consumer electronics applications. The 2.1 W rating and 265 VAC capability make it suitable for mains-connected devices. Consider the thermal time constant and steady-state resistance characteristics to ensure effective circuit protection against startup surges.

Part Context

This device belongs to the B57236S0 series of leaded and coated NTC thermistors designed primarily for inrush current limiting. The series offers a wide range of resistance values while maintaining consistent mechanical and electrical performance characteristics across different manufacturers within the TDK group.

Replacement Considerations

Compatible substitutes include other B57236S0 series variants with matching resistance and power ratings. Cross-reference with equivalent ICL components from other manufacturers ensuring identical voltage ratings, thermal characteristics, and physical footprint compatibility.
