NF08AA0809MHB

Inrush Current Limiters (ICL) Overview

The KYOCERA AVX NF08AA0809MHB is a leaded inrush current limiter (ICL) designed for circuit protection. It features an initial resistance of 8 Ohms with a tolerance of ±20%. The device supports a maximum steady-state current of 2.3 A and exhibits a hot resistance of 300 mOhms at rated current. The component has a cylindrical body diameter of 8.00 mm (0.315 inches). It is supplied in bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Provides passive inrush current limiting to protect downstream components during power-up.
• Features low hot resistance to minimize power loss during normal operation.
• Utilizes a robust leaded package suitable for through-hole mounting applications.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary side protection
• Capacitor bank charging circuits

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific thermal derating curves and energy absorption capabilities against your application's peak inrush requirements. Confirm that the steady-state current rating of 2.3 A aligns with the continuous load conditions. Ensure the physical dimensions fit the designated PCB footprint, as this is a leaded component requiring through-hole placement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a simple, cost-effective solution for limiting initial surge currents is required. It is appropriate for applications where the inrush event duration is short and the steady-state current remains below 2.3 A. Consider thermal management on the PCB to dissipate heat generated during the high-current transient phase.

Inrush Current Limiters (ICL) Part Context

This part belongs to the family of inrush current limiters manufactured by KYOCERA AVX. These devices are distinct from active protection circuits, offering a passive approach to managing startup surges. They are commonly used in conjunction with fuses or circuit breakers to provide comprehensive overcurrent protection strategies.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 8 Ohm initial resistance, 2.3 A steady-state current rating, and 8 mm diameter. Verify that alternative manufacturers offer compatible thermal characteristics and lead configurations to ensure mechanical and electrical compatibility without redesigning the PCB layout.
