MF72-010D15

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-010D15 is a negative temperature coefficient (NTC) thermistor designed as an inrush current limiter (ICL). 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 5 A and exhibits a low hot resistance of 275 mOhms. Its physical dimensions include a diameter of 0.689 inches (17.50mm), ensuring compatibility with standard through-hole mounting configurations.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high initial surge currents during power-up sequences
• Utilizes NTC material properties to automatically increase resistance as temperature rises
• Maintains low steady-state resistance to minimize power loss during normal operation

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Transformer primary winding protection
• Capacitor charging circuit limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix D15 against the official datasheet to confirm the lead length and package variant matches the design requirements. Ensure the thermal environment allows for adequate heat dissipation, as the component's performance depends on ambient temperature conditions. Cross-reference the manufacturer's latest RoHS compliance status before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 10 Ohm cold resistance and 5 A continuous current rating. Evaluate the peak energy absorption capability to ensure it withstands the specific application's surge profile without failure. Consider the physical size constraints imposed by the 17.50mm diameter when designing the PCB layout or enclosure space.
