MF72-016D15

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-016D15 is a power NTC thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 16 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 4 A and has a diameter of 0.689 inches (17.50mm). Its low-resistance state under operating current is specified as 276 mOhms.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting for power supply circuits
• Utilizes negative temperature coefficient characteristics for self-regulating protection
• Designed for robust performance in high-current applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• General electronic equipment surge suppression

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific lead times and availability directly with authorized distributors, as stock levels fluctuate. Confirm that the 17.50mm diameter and axial lead spacing match the target PCB layout requirements before finalizing orders to ensure mechanical compatibility.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 16 Ohm initial resistance and 4 A steady-state current rating are required. Ensure the application environment stays within the specified operating temperature range. Verify that the 276 mOhms hot resistance meets the system's power dissipation constraints during normal operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MF72 series of power NTC thermistors manufactured by Cantherm. The series is engineered for circuit protection against high initial charging currents. The MF72-016D15 variant specifically targets applications requiring higher initial impedance compared to lower ohmic counterparts in the same family.
