B57153S0150M051

Overview

The B57153S0150M051 is a radial lead NTC thermistor designed for inrush current limiting. It features a nominal resistance of 15 Ω at 25°C with a tolerance of ±20%. The component has a maximum rated power of 1.4 W and withstands voltages up to 115 VAC or 230 VAC. Physical dimensions include an 8.5 mm diameter, 6 mm width, and 13 mm height. It operates within a temperature range of -55°C to +170°C and utilizes a 5 mm lead spacing.

Feature Summary

Provides effective protection against high surge currents during power-up phases
Utilizes negative temperature coefficient characteristics to reduce resistance as temperature increases
Supports PCB mounting with radial leads for straightforward integration

Applications

Inrush current protection in AC-DC power supplies
Surge limitation in LED driver circuits
Industrial electronics requiring component safeguarding

Procurement Notes

Verify the specific suffix M051 against official TDK documentation to confirm lead length and packaging specifications. Ensure the selected variant matches the required voltage rating and thermal time constant for the target application. Cross-reference the manufacturer part number to avoid confusion with similar series components that may have different physical or electrical constraints.

Selection Notes

Select this component based on the 15 Ω initial resistance and 1.4 W power rating requirements. Confirm compatibility with the system's operating voltage limits of 115 VAC or 230 VAC. Evaluate the thermal environment to ensure the -55°C to +170°C range meets operational needs. Consider the 5 mm lead spacing for appropriate PCB footprint design and mechanical stability.
