MF72-001.5D25

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-001.5D25 is a negative temperature coefficient (NTC) thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 1.5 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 10 A and exhibits a low hot resistance of 40 mOhms. Its physical dimensions include a diameter of 1.083 inches (27.50 mm) and a lead spacing of 0.307 inches (7.80 mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides effective protection against high initial surge currents during power-up sequences.
• Utilizes self-heating properties to rapidly reduce resistance after the initial transient phase.
• Constructed for robust performance in demanding electrical environments.

Inrush Current Limiters (ICL) Applications

• Transformer inrush current suppression
• Switching power supply input protection
• Motor circuit surge limitation

Inrush Current Limiters (ICL) Procurement Notes

Verify that the replacement part matches the original 1.5 Ohm resistance value and 10 A current rating. Confirm dimensional compatibility, specifically the 27.50 mm diameter and 7.80 mm lead spacing, to ensure proper mounting. Check for required safety certifications such as UL or CSA if applicable to the end equipment.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the application requires limiting high inrush currents up to 10 Amperes. Ensure the system voltage and thermal environment are compatible with the device's operating characteristics. Consider the specific resistance value needed to balance surge suppression effectiveness with steady-state power loss.
