MF72-010D25

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-010D25 is an NTC thermistor inrush current limiter (ICL) designed for power circuit protection. It features a nominal resistance of 10 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 7 A and exhibits a low hot resistance of 30 mOhms. Its physical dimensions include a diameter of 1.083 inches (27.50mm) and a lead spacing of 0.295 inches (7.50mm).

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting during power-up phases to protect downstream components.
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature rises.
• Features robust construction suitable for high-energy switching applications.

Inrush Current Limiters (ICL) Applications

• Power supplies and inverters
• Uninterruptible Power Supplies (UPS)
• Energy saving lamps

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix D25 corresponds to the required 27.50mm diameter and 7A rating, as the MF72 series contains variants with different physical sizes and current capacities. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the lead spacing matches the PCB footprint requirements before ordering.

Inrush Current Limiters (ICL) Selection Notes

Select this model when the application requires a 10 Ohm initial resistance to limit surge currents up to 7 Amperes. The larger 27.50mm diameter indicates higher energy absorption capability compared to smaller variants. Verify that the operating environment remains within the specified thermal limits to ensure reliable long-term performance in the target circuit.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Cantherm MF72 series of power NTC thermistors. These devices are specifically engineered for inrush current limiting in AC/DC power circuits. The series offers various resistance values and physical sizes to accommodate different current ratings and energy dissipation needs across industrial and consumer electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires matching the 10 Ohm resistance, 7A steady-state current, and 27.50mm diameter specifications precisely.
