ICL155R007-01

Inrush Current Limiters (ICL) Overview

The Honeywell ICL155R007-01 is a Positive Temperature Coefficient (PTC) resettable fuse designed for inrush current limiting applications. It features a nominal resistance of 5 Ohms with a tolerance of ±20% and supports a continuous current rating of 7 A. The component operates within voltage ratings of 115 VAC and 230 VAC. Physically, it measures 15.00 mm (0.591 inches) in diameter and utilizes radial kinked leads for PCB mounting.

Inrush Current Limiters (ICL) Feature Summary

• Provides cost-effective protection against inrush currents that may damage switching power supply components
• Functions as a self-resetting device to restore circuit continuity after fault conditions clear
• Utilizes PTC thermistor technology for reliable thermal response in power devices

Inrush Current Limiters (ICL) Applications

• Switching power supplies
• HMI and display projects with external peripherals
• General power device protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the manufacturer designation carefully, as the ICL155R007-01 is identified as a Honeywell product in official listings but shares similar part numbers with Vishay/Ametherm NTC limiters. Confirm the specific package style and lead configuration matches the required PCB layout. Ensure the application voltage does not exceed the rated 230 VAC limit. Cross-reference datasheets to distinguish between PTC resettable fuses and standard NTC inrush limiters before procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a resettable solution is preferred over disposable fuses for managing initial surge currents. The 5 Ohm resistance value is suitable for limiting peak charging currents in capacitive loads. Consider the 7 A continuous current rating to ensure the device remains within its safe operating area during normal operation. Verify thermal dissipation requirements based on the ambient temperature and duty cycle of the target equipment.

Inrush Current Limiters (ICL) Part Context

This component belongs to the ICL series of inrush current limiters manufactured by Honeywell Sensing and Productivity Solutions. It serves as a protective element in electronic circuits where sudden current spikes upon power-up could compromise sensitive downstream components. The series offers various resistance and current ratings to accommodate different power supply designs.
