MF72-047D15

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-047D15 is a negative temperature coefficient (NTC) thermistor inrush current limiter designed for circuit protection. It features a nominal resistance of 47 Ohms with a tolerance of ±20% at 25°C. The component supports a steady-state maximum current of 3 A and operates within a temperature range of -55 °C to 200 °C. It utilizes a radial through-hole mount configuration with wire terminals, housed in a disk package measuring 0.689 inches (17.50mm) in diameter.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting during power-up phases to protect downstream components.
• Utilizes NTC thermistor technology to automatically reduce resistance as temperature increases.
• Supports through-hole mounting for reliable integration into industrial control circuits.

Inrush Current Limiters (ICL) Applications

• Overload protection in electronic circuits
• Inrush current suppression in power supplies

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific resistance value and physical dimensions against the official datasheet before implementation. Confirm that the steady-state current rating aligns with the application's operational requirements. Ensure the operating temperature range covers the expected environmental conditions. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 47 Ohm initial resistance is required to limit surge currents up to 3 Amperes. Consider the 17.50mm diameter for available board space and thermal dissipation needs. Evaluate the ±20% tolerance to ensure it meets the circuit's sensitivity constraints. Verify compatibility with the target voltage ratings and mechanical mounting style.
