ICL251D15MIC

Inrush Current Limiters (ICL) Overview

The ICL251D15MIC is an NTC thermistor from the Eaton ICL family, functioning as an inrush current limiter. It features a nominal resistance of 25 Ohms with a tolerance of ±20%. The component has a B-parameter of 3200 K and utilizes I-leads with a body size of 15 mm (0.630 inches). It is rated for a steady-state current of 3.5 A. The device employs J Beta tolerance and B1 Beta definition standards. Packaging is provided in bulk quantities.

Inrush Current Limiters (ICL) Feature Summary

• Negative temperature coefficient characteristic for inrush current limiting
• I-lead configuration for through-hole mounting
• B1 Beta definition standard for thermal modeling

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet revision to confirm electrical ratings and mechanical dimensions match design requirements. Ensure the I-lead style and 15 mm body size are compatible with the target PCB layout. Confirm compliance with RoHS directives if required by the end product specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 25 Ohm initial resistance and 3.5 A steady-state current rating are required. The 3200 K B-parameter indicates specific thermal sensitivity suitable for general inrush limiting. Consider the bulk packaging format for assembly processes that do not require tape and reel.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors designed specifically for managing high initial currents. The series offers various resistance values and lead styles to accommodate different circuit power levels and physical constraints within electronic equipment.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other ICL family parts such as ICL151D15MIC or ICL801D13MIC only if resistance and current ratings align with the application needs. Verify lead type and body dimensions before substitution.
