B57153S0160M054

Overview

The B57153S0160M054 is a negative temperature coefficient (NTC) thermistor inrush current limiter manufactured by TDK Electronics. It features a nominal resistance of 16 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 2.9 A and operates within voltage ratings of 115 VAC or 230 VAC. It has a radial package with an 8.5 mm diameter, 5.0 mm lead spacing, and 0.6 mm lead diameter. The device functions across a temperature range of -55°C to +170°C.

Feature Summary

• Provides effective suppression of high inrush currents during power-up cycles
• Utilizes NTC thermistor technology for automatic resistance adjustment based on temperature
• Designed for robust PCB mounting with standardized radial lead configuration

Applications

• Power supply input stages
• Consumer electronic devices
• Industrial control systems

Procurement Notes

Verify the specific ordering code against official TDK Electronics documentation to ensure correct resistance and tolerance specifications. Confirm that the component status aligns with design requirements, as availability may vary. Cross-reference the datasheet for thermal characteristics and mechanical dimensions to guarantee compatibility with the target printed circuit board layout and operational environment.

Selection Notes

Select this component based on the required peak inrush current magnitude and the operating voltage levels of the application circuit. Ensure the steady-state current rating exceeds the maximum continuous load current. Evaluate the thermal management capabilities of the system to accommodate the self-heating effects inherent to NTC limiters during normal operation.

Part Context

This part belongs to the S153 series of NTC thermistors produced by TDK Electronics, formerly EPCOS. The series is engineered for circuit protection applications requiring reliable surge current limitation. TDK Electronics continues the legacy of passive component manufacturing established by its predecessor entities.

Replacement Considerations

Consult official TDK Electronics substitution guides for verified alternative part numbers. Direct replacements must match electrical parameters including resistance, current rating, and physical dimensions.
