B57153S0100M051

Overview

The B57153S0100M051 is an NTC thermistor designed for inrush current limiting, manufactured by TDK. It features a nominal resistance of 10 Ohms with a tolerance of ±20%. The component supports steady-state currents up to 2 A and operates at voltage ratings of 110 VAC and 230 VAC. Physical dimensions include an 8.5 mm diameter and 6 mm width, with a lead spacing of 5 mm. It functions within a temperature range of -55°C to +170°C and has a power rating of 1.4 W.

Feature Summary

• Passive inrush current limitation without control signals or bias power
• Radial leaded construction for PCB mounting
• High thermal stability across wide operating temperatures

Applications

• Switching power supply input stages
• Consumer electronics power circuits
• Industrial equipment protection

Procurement Notes

Verify the manufacturer part number against official TDK documentation to ensure accuracy, as legacy EPCOS designations may vary. Confirm that the specific suffix matches the required electrical parameters and packaging format. Cross-reference datasheet revisions to avoid obsolete variants. Ensure compliance with RoHS standards if required by the application environment.

Selection Notes

Select this component based on the 10 Ohm resistance value and 2 A current rating requirements. Consider the 8.5 mm radial package size for board layout constraints. Evaluate the thermal dissipation characteristics relative to the ambient operating conditions. Compare against alternative resistances in the S153 series if different limiting profiles are needed.

Part Context

This component belongs to the B57153S series of NTC thermistors originally developed by EPCOS, now under TDK Electronics. These devices are specifically engineered for circuit protection applications where passive surge suppression is required. The series offers standardized dimensions and electrical characteristics for consistent integration into various electronic systems.

Replacement Considerations

Compatible substitutes within the same family include B57153S0200M051 and B57153S0330M051V9. Verify that the replacement part meets the specific resistance and current handling requirements of the original design before implementation.
