B57235S0100M000

Overview

The B57235S0100M000 is a radial lead NTC thermistor designed for inrush current limiting applications. It features a nominal resistance of 10 Ω at 25°C with a tolerance of ±20%. The component has a maximum steady-state current rating of 3 A and a power dissipation of 1800 mW. Dimensions include a diameter of 9.5 mm, height of 6 mm, and lead length of 39 mm. It operates within a temperature range of -55°C to 170°C and exhibits a thermal time constant of 60 seconds.

Feature Summary

• Negative temperature coefficient design for effective inrush current suppression
• Radial leaded construction suitable for PCB mounting
• High long-term stability under high temperature and humidity conditions

Applications

• Inrush current limiting in electronic circuits
• Power supply input protection
• Industrial equipment surge suppression

Procurement Notes

Verify the specific part number suffix against official TDK documentation to confirm exact electrical tolerances and package dimensions. Ensure that the selected variant meets the required steady-state current and power dissipation ratings for the target application. Cross-reference certification standards such as IEC 60068-2-78 if environmental testing compliance is mandatory for the project.

Selection Notes

Select this component based on the required nominal resistance value of 10 Ω and the maximum steady-state current capacity of 3 A. Consider the physical dimensions, specifically the 9.5 mm diameter and 6 mm height, to ensure compatibility with the printed circuit board layout. Evaluate the thermal time constant of 60 seconds to determine the response speed relative to the system's operational requirements.

Part Context

This component belongs to the B57235S0M0 series manufactured by EPCOS, now operating under TDK Electronics. The series is specialized for inrush current limiting tasks. EPCOS was integrated into the TDK group, with its operations managed under TDK Electronics AG since 2018. This product line utilizes NTC technology to protect sensitive electronic components from initial power surges.
