ST5R014B

Overview

The Littelfuse ST5R014B is a leaded inrush current limiter (ICL) belonging to the ST Series. It features a nominal resistance of 5 Ohms with a tolerance of ±20%. The device supports a maximum steady-state current of 14 Amperes and has an axial lead diameter of 0.04 inches. The component body measures approximately 1.475 inches (37.47mm) in length. This thermistor-based component is designed for circuit protection applications requiring controlled current limiting.

Feature Summary

Provides effective inrush current limitation for sensitive electronic circuits
Utilizes positive temperature coefficient thermistor technology for self-resetting protection
Features axial leads for through-hole mounting configurations

Applications

Power supply input stages
Transformer primary side protection
Capacitive load switching circuits

Procurement Notes

Verify component availability status as distribution sources may list this part as obsolete or end-of-life. Confirm exact physical dimensions and lead specifications against schematic requirements. Ensure thermal management considerations align with the 14A current rating for the specific application environment.

Selection Notes

Select this component based on the required 5-ohm initial resistance and 14-ampere continuous current capacity. Evaluate the package size constraints regarding the 1.475-inch body length. Consider the operating temperature range and reset time characteristics relative to the system's duty cycle requirements.

Part Context

This part belongs to the ST Series of inrush current limiters manufactured by Littelfuse Inc. The series utilizes NTC/PTC thermistor materials to manage surge currents during power-up phases. These components are distinct from fuses as they do not require replacement after tripping, offering reusable circuit protection solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent ST Series variants or consult manufacturer guidelines for direct replacements.
