MF72-012D13

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-012D13 is a negative temperature coefficient (NTC) thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 12 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 3 A and has a stabilized resistance of 92 mOhms. Physical dimensions include a diameter of 0.610 inches (15.50mm) and a lead spacing of 0.295 inches (7.50mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high inrush currents during power-up sequences.
• Utilizes NTC thermistor technology for automatic resistance adjustment based on temperature.
• Designed for through-hole mounting with radial wire leads.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'D13' to confirm the 15.50mm diameter and 7.50mm lead spacing match the design requirements. Confirm that the 12 Ohm nominal resistance and 3 A steady-state current rating are sufficient for the target application's peak load conditions. Ensure the operating temperature range aligns with the system environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 12 Ohm initial resistance is required to limit surge current. The 3 A steady-state rating must exceed the circuit's normal operating current. Consider the physical size constraints, as the 15.50mm diameter requires adequate board space. Verify compatibility with the assembly process for through-hole components.
