B57237S0600M051

Inrush Current Limiters (ICL) Overview

The B57237S0600M051 is an NTC thermistor inrush current limiter from the S237 series, designed for PCB mounting. It features a nominal resistance of 60 Ohms with a tolerance of ±20%. The component has a maximum continuous current rating of 2 A and voltage ratings of 115 VAC or 230 VAC. Physical dimensions include a diameter of 15 mm, width of 7 mm, lead spacing of 7.5 mm, and lead diameter of 0.8 mm. It operates within a temperature range of -55°C to +170°C, with a power rating of 3.1 W and a dissipation factor of 17 mW/K.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient (NTC) characteristics to limit high initial charging currents during power-up.
• Provides radial through-hole termination for secure PCB integration.
• Engineered for robust performance across wide industrial operating temperatures.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Switch-mode power supplies (SMPS)

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix M051 against official TDK documentation to confirm packaging configuration. Ensure that the selected variant matches the required reel or cut tape specifications for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 60 Ohm cold resistance and 2 A steady-state current capability. Confirm that the 15 mm diameter fits the available board space and that the 7.5 mm lead spacing aligns with the PCB footprint design. Validate thermal management requirements against the 3.1 W power rating and ensure the application voltage does not exceed the 230 VAC limit.
