MF72-006D20

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-006D20 is a power NTC thermistor designed for inrush current limiting. It features a resistance of 6 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 6 A and has a diameter of 0.886 inches (22.50 mm). It operates within a temperature range of -55°C to 200°C and utilizes through-hole mounting with radial wire leads.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of surge currents to protect sensitive electronic components from damage during power-up.
• Constructed as a negative temperature coefficient thermistor that reduces resistance as it heats up, allowing efficient steady-state operation.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes
