B57236S0259L002

Overview

The B57236S0259L002 is a leaded NTC thermistor from the EPCOS (TDK) B57236S0 series, designed for inrush current limiting. It features a cold resistance of 2.5 Ω at 25°C with a tolerance of ±15%. The component has a maximum steady-state current rating of 5.5 A and a power rating of 2.1 W. It utilizes an 11.5 mm diameter disk package with radial leads. The operating temperature range spans from -55°C to 170°C.

Feature Summary

• Provides effective inrush current limitation during power-up phases
• Features a robust coated disk construction for thermal stability
• Supports high steady-state current handling capabilities

Applications

• Power supply input stages
• Electronic ballast circuits
• Motor drive protection

Procurement Notes

Verify the specific suffix L002 against official TDK documentation to confirm the exact resistance tolerance and packaging configuration. Ensure the selected variant matches the required steady-state current and thermal dissipation parameters for the target application circuit design.

Selection Notes

Select this component based on the 2.5 Ω initial resistance and 5.5 A current capacity. Evaluate the thermal time constant and energy absorption limits to ensure compatibility with the system's power-up profile and ambient operating conditions.

Part Context

This part belongs to the B57236S0 series of leaded NTC thermistors manufactured by EPCOS, now part of the TDK Group. These components are specifically engineered for circuit protection applications where controlling surge currents is critical for maintaining system integrity.

Replacement Considerations

Consult official TDK substitution lists for compatible alternatives within the B57236S0 family. Verify that any substitute maintains identical electrical ratings, physical dimensions, and certification approvals.
