B57153S100M54

Overview

The B57153S100M54 is an inrush current limiter (ICL) manufactured by TDK Electronics, formerly EPCOS. This component belongs to the S153 series and features a nominal resistance of 10 Ohms with a tolerance of ±20%. It is rated for a maximum steady-state current of 2 A and has a physical diameter of 8.50 mm (0.335 inches). The device is designed for circuit protection applications, offering reliable performance in limiting initial surge currents during power-up phases.

Feature Summary

• Provides effective inrush current limitation to protect sensitive electronic components from high initial surge currents.
• Features a compact radial leaded design suitable for through-hole mounting on printed circuit boards.
• Constructed with NTC thermistor technology that exhibits negative temperature coefficient characteristics.

Applications

• Power supply input stages requiring surge current suppression
• Consumer electronics circuits needing component protection
• Industrial control systems utilizing AC/DC conversion

Procurement Notes

Verify the specific ordering suffix matches the required resistance and current ratings. Confirm package type availability such as cut tape or tape and reel options. Ensure compliance with RoHS3 and REACH regulations for environmental standards. Check datasheet for thermal derating curves relevant to your operating environment.

Selection Notes

Select this component based on the required steady-state current handling capability of 2 A. Consider the initial resistance value of 10 Ohms for appropriate surge limiting. Evaluate the physical dimensions to ensure compatibility with PCB layout constraints. Review the thermal characteristics to maintain safe operating temperatures under continuous load conditions.

Part Context

This part is part of the TDK Electronics S153 series of NTC inrush current limiters. The brand was historically known as EPCOS before merging into TDK's component division. These components are widely used in various electronic applications for circuit protection against high inrush currents.

Replacement Considerations

Compatible substitutes include other NTC inrush current limiters with similar electrical specifications. Verify equivalent resistance, current rating, and physical footprint when selecting alternatives. Consult manufacturer cross-reference lists for direct replacements within the same product family.
