MF72-030D15

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-030D15 is a power NTC thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 30 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 3.5 Amperes and has a disc diameter of 0.689 inches (17.50mm). It operates within a temperature range of -55°C to 200°C, providing reliable circuit protection against high initial surge currents during power-up phases.

Inrush Current Limiters (ICL) Feature Summary

• Functions as a non-linear resistor to suppress high inrush currents upon power application
• Utilizes negative temperature coefficient characteristics for automatic resistance adjustment
• Designed for robust thermal stability across wide operating temperature ranges

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Motor drive protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix D15 corresponds to the required 17.5mm diameter and 3.5A rating. Confirm lead times as these components are often manufactured to order. Ensure compatibility with peak pulse energy requirements for the target application.

Inrush Current Limiters (ICL) Selection Notes

Select based on the required steady-state current handling and initial resistance value. Verify that the physical dimensions fit the PCB layout or mounting constraints. Consider the thermal dissipation capabilities relative to the ambient environment and duty cycle.
