CL13270130

Inrush Current Limiters (ICL) Overview

The CL13270130 is a Positive Temperature Coefficient (PTC) Inrush Current Limiter manufactured by Vishay Ametherm. It features a nominal resistance of 27 Ohms with a tolerance of ±25%. The device is designed for operation at a maximum temperature of 130°C and has a physical diameter of 12mm. This component serves as an NTC thermistor alternative in specific thermal management applications, providing high initial resistance that drops as current flows.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes PTC technology to limit inrush current during power-up sequences
• Provides automatic reset functionality after fault conditions clear
• Designed for through-hole mounting on printed circuit boards

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• Capacitor charging circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the CL13270130 to confirm thermal characteristics and mechanical dimensions. Ensure the application environment does not exceed the 130°C maximum operating temperature rating. Cross-reference the 27 Ohm resistance value against circuit requirements to ensure adequate inrush limiting performance without excessive steady-state voltage drop.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a PTC response is required rather than standard NTC behavior. Verify that the 12mm package size fits within the available PCB area. Confirm that the 27 Ohm initial resistance aligns with the target inrush current limits for the specific load being protected.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Vishay Ametherm thermistor portfolio, specifically categorized under PTC inrush current limiters. It differs from the company's NTC series by offering positive temperature coefficient characteristics suitable for distinct overcurrent protection strategies.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other Vishay Ametherm PTC devices or generic equivalents only if they match the 27 Ohm resistance, 12mm diameter, and 130°C temperature ratings.
