MF72-010D20

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-010D20 is a negative temperature coefficient (NTC) thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 10 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 6 A and exhibits a stabilized resistance of 92 mOhms under operating conditions. Physically, it utilizes a radial through-hole mounting configuration with a disk package shape. The unit measures 0.886 inches (22.50 mm) in diameter and has a lead spacing of 0.295 inches (7.50 mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high initial surge currents during power-up sequences.
• Automatically transitions to a low-resistance state after thermal activation to minimize operational power loss.
• Constructed for robust through-hole integration into printed circuit boards.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation against the manufacturer's datasheet to confirm physical dimensions and electrical ratings. Ensure the selected variant matches the required steady-state current capacity and ambient operating temperature range for the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Evaluate the peak inrush current magnitude and duration to ensure the component can absorb the energy without failure. Confirm that the steady-state current does not exceed the rated limit to prevent overheating. Check mechanical clearance requirements for the 22.50 mm diameter and verify lead spacing compatibility with the PCB layout.
