MF72-001.3D13

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-001.3D13 is an NTC thermistor inrush current limiter (ICL) designed for power circuit protection. It features a nominal resistance of 1.3 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 7 A and exhibits a hot resistance of 0.062 Ohms. It has a cylindrical body diameter of 0.610 inches (15.50 mm) and a lead spacing of 0.295 inches (7.50 mm). The device is rated for a maximum operating temperature of 60°C and withstands peak surge currents up to 880 A.

Inrush Current Limiters (ICL) Feature Summary

• Utilizes negative temperature coefficient technology to limit high initial charging currents during power-up.
• Provides automatic reset functionality, returning to high resistance state after the circuit stabilizes.
• Constructed with axial leads for through-hole mounting on printed circuit boards.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify that the ordering suffix D13 corresponds to the specific lead configuration and packaging format required for your assembly process. Confirm that the 1.3 Ohm resistance value aligns with the calculated inrush current requirements of the target application. Ensure the 7 A steady-state current rating exceeds the operational load to prevent thermal failure. Check RoHS compliance status if environmental regulations apply to the final product.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required resistance value to achieve the desired inrush current limitation ratio. Ensure the physical dimensions fit within the available PCB area and enclosure constraints. Verify that the maximum surge current capability matches the energy levels present in the input stage. Consider the thermal dissipation characteristics and ambient temperature conditions during continuous operation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MF72 series of power NTC thermistors manufactured by Cantherm. The series offers various resistance values and package sizes to accommodate different power ratings. These components are specifically engineered for protecting sensitive electronic circuits from damage caused by high transient currents during startup phases.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 1.3 Ohm nominal resistance, 7 A current rating, and 15.50 mm diameter. Verify that alternative manufacturers provide equivalent surge current capabilities and thermal characteristics. Ensure the replacement part maintains the same axial lead spacing for board compatibility without redesigning the footprint.
