MF72-050D11

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-050D11 is a negative temperature coefficient (NTC) thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 50 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 1.5 A and has a physical diameter of 0.512 inches (13.00 mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides effective surge current suppression to protect sensitive electronic components.
• Utilizes NTC characteristics for automatic resistance adjustment during operation.

Inrush Current Limiters (ICL) Applications

• Power supply input protection
• Surge current limiting in electronic circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific electrical parameters, particularly the 50 Ohm resistance and 1.5 A current rating, against the official manufacturer datasheet before integration. Confirm that the 13.00 mm diameter and lead spacing meet the mechanical constraints of the target PCB layout. Ensure compliance with relevant environmental directives such as RoHS if required by the end product specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the circuit requires a higher initial resistance value compared to standard low-resistance ICLs. The 50 Ohm rating is suitable for applications where peak inrush currents are moderate but require significant initial impedance. Evaluate the thermal dissipation requirements to ensure the 1.5 A steady-state limit is not exceeded under worst-case operating conditions.

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 cost-effective inrush current control. The MF72-050D11 represents a specific variant within this family, distinguished by its 50 Ohm resistance and 13 mm form factor, differentiating it from lower resistance or larger diameter models in the same line.
