NF13AA0330M--

Inrush Current Limiters (ICL) Overview

The KYOCERA AVX NF13AA0330M-- is a leaded inrush current limiter (ICL) designed to protect electronic circuits from high initial charging currents. This component features a nominal resistance of 33 Ohms with a tolerance of ±20%. It supports a continuous current rating of 2.2 Amperes and utilizes a 0.512-inch (13.00mm) body size for standard through-hole mounting applications.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective protection against high inrush currents during power-up sequences
• Features self-resetting behavior after thermal cooling following overload events
• Constructed with a robust ceramic element housed in a shrink tube package

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• Motor drive circuit inputs
• General consumer electronics power entry

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix codes on the physical component against the manufacturer's official datasheet to confirm exact electrical ratings and packaging specifications. Ensure that the selected variant matches the required continuous current and peak surge capabilities for the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the steady-state operating current not exceeding the 2.2A rating. Consider the thermal dissipation requirements in the final assembly, as the device operates by heating up to limit current flow. Ensure adequate spacing is maintained around the component to allow for proper heat dissipation.

Inrush Current Limiters (ICL) Part Context

This part belongs to the family of positive temperature coefficient (PTC) thermistors used for overcurrent and inrush protection. Unlike fuses, these devices do not require replacement after tripping, offering a reusable solution for transient current limiting in various industrial and commercial power systems.

Inrush Current Limiters (ICL) Replacement Considerations

Confirm that any substitute part maintains the same 33 Ohm resistance at room temperature and meets or exceeds the 2.2A continuous current rating. Verify that the physical footprint and lead configuration are compatible with the existing PCB layout.
