ICL501D15MIC

Inrush Current Limiters (ICL) Overview

The ICL501D15MIC is an NTC thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 50 ohms at standard reference temperature and utilizes lead (I) leads for mounting. The component has a physical size of 15 mm and employs a B1 beta definition with a beta parameter of 3400 K. Beta tolerance is specified as J class. This device functions by exhibiting high initial resistance to limit surge currents, which decreases as self-heating occurs during operation.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter using negative temperature coefficient characteristics
• Features lead-mounted construction for direct circuit integration
• Provides high initial resistance that drops significantly upon thermal activation

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Transformer primary side current limiting
• Capacitor charging circuit protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the ICL501D15MIC to confirm electrical ratings and mechanical dimensions. Ensure compatibility with the target application's voltage and current requirements. Check for RoHS compliance status if required by project specifications. Confirm package type and lead configuration match the design layout.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current and peak inrush current limits. The 50-ohm resistance value determines the initial surge limitation capability. Consider the 15 mm size constraint for PCB or chassis mounting. Evaluate the 3400 K beta value for thermal response characteristics relative to the operating environment.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current control. These components are widely used in electronic power supplies and industrial equipment to protect sensitive downstream components from high startup currents. The series offers various resistance values and sizes to suit different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 50-ohm resistance, 15 mm size, and leaded package style. Verify equivalent beta parameters and current ratings. Consult Eaton documentation for cross-reference lists.
