PTCEL13R102SBE

Inrush Current Limiters (ICL) Overview

The PTCEL13R102SBE is a Positive Temperature Coefficient (PTC) thermistor inrush current limiter manufactured by Vishay Beyschlag/Draloric/BC Components. It features a nominal resistance of 1 kOhms with a tolerance of ±30%. The device has a cylindrical body diameter of 0.531 inches (13.50mm). It is designed for axial lead mounting and operates within standard electronic environments.

Inrush Current Limiters (ICL) Feature Summary

• Positive temperature coefficient behavior for automatic resistance increase during thermal events
• Designed specifically to limit inrush current during power-up cycles
• Robust axial leaded construction for through-hole PCB integration

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Electronic equipment protection circuits
• Consumer appliance power entry modules

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for precise maximum voltage and current ratings before finalizing the design. Confirm that the physical dimensions align with the target PCB footprint. Ensure the application environment does not exceed the component's thermal limits to maintain reliable operation over the product lifecycle.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a robust, cost-effective solution for limiting initial surge currents is required. The 1 kOhm nominal value provides significant impedance at startup, which decreases as the device heats up. Consider the thermal mass and ambient temperature conditions to ensure proper trip characteristics are achieved without nuisance tripping during normal operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the PTCEL series of PTC thermistors from Vishay BC Components. These devices are widely used in general-purpose electronics to protect sensitive components from high initial charging currents. The series offers various resistance values and package sizes to suit different power requirements and board space constraints.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 1 kOhm nominal resistance, ±30% tolerance, and 13.50mm diameter. Verify that alternative parts support the same axial lead configuration and meet equivalent electrical safety standards for inrush limiting applications.
