MF72-008D7

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-008D7 is a power NTC thermistor designed as an inrush current limiter (ICL). It features a nominal resistance of 8 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 1 A and has a diameter of 9.00 mm (0.354 inches). It belongs to the MF72 series, which utilizes negative temperature coefficient characteristics to effectively suppress surge currents during equipment startup.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of surge currents to protect sensitive electronic components from damage during power-up sequences.
• Utilizes negative temperature coefficient properties to transition from high initial resistance to low operating resistance.
• Offers a cost-effective solution for managing inrush energy in various electronic applications.

Inrush Current Limiters (ICL) Applications

• Surge current protection in power supply circuits
• Inrush current limiting for sensitive electronic devices
