MF72-001.5D15

Inrush Current Limiters (ICL) Overview

The Cantherm MF72-001.5D15 is an inrush current limiter (ICL) from the MF72 series, designed for circuit protection against high initial current surges. It features a nominal resistance of 1.5 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 8 A and has a diameter of 17.50 mm (0.689 inches). It utilizes a lead spacing of 10.00 mm (0.394 inches) and exhibits a resistance of 0.052 Ohms at rated current.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of inrush currents during power-up sequences to protect sensitive electronic components.
• Constructed as a negative temperature coefficient (NTC) thermistor that transitions from high resistance to low resistance as it heats up.
• Designed for robust performance within power circuits, ensuring stable operation under continuous load conditions.

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 part number suffix to ensure correct resistance and dimensional specifications match the design requirements. Confirm RoHS compliance status and approval agency certifications such as UL or CSA if required by the target market regulations. Check manufacturer datasheets for thermal derating curves and maximum energy absorption ratings to validate suitability for the intended application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance value of 1.5 Ohms and the maximum steady-state current rating of 8 A. Ensure the physical dimensions, specifically the 17.50 mm diameter and 10.00 mm lead spacing, fit the available board space or mounting configuration. Consider the thermal characteristics and time constant to guarantee adequate inrush current limitation for the specific load profile.
