ESD-R-421617H-NC23

Overview

The KEMET ESD-R-421617H-NC23 is a nanocrystal ferrite toroid designed for noise suppression on round cables. It features an inner diameter of 16.7 mm and an outer diameter of 42 mm, with a height of 17 mm. The component operates effectively up to 300 MHz and is rated for temperatures up to 120°C. Constructed from nanocrystalline material, it provides high impedance for electromagnetic interference reduction in electronic assemblies.

Feature Summary

• Utilizes nanocrystalline material for effective broadband noise suppression
• Solid toroidal geometry optimized for round cable applications
• High thermal stability supporting operation up to 120°C

Applications

• Electromagnetic interference filtering on signal and power cables
• Common mode noise suppression in electronic equipment
• Cable assembly protection against radio frequency interference

Procurement Notes

Verify the specific nanocrystal formulation and dimensional tolerances against the official KEMET datasheet before integration. Confirm that the 16.7 mm inner diameter accommodates the target cable bundle without excessive strain. Ensure the operating environment remains within the specified 120°C thermal limit to maintain material performance characteristics.

Selection Notes

Select this component when high-frequency noise attenuation is required on round cables where standard ferrites are insufficient. The nanocrystal composition offers superior permeability compared to traditional materials. Evaluate the physical space constraints against the 42x17 mm external dimensions to ensure proper fit within the enclosure or harness layout.

Part Context

This part belongs to the KEMET ESD-R-NC series of solid ferrite rings. The series utilizes advanced nanocrystalline technology to deliver enhanced magnetic properties in a compact form factor. These cores are distinct from powdered iron or manganese-zinc variants, offering specific advantages for high-frequency suppression tasks in modern electronics.

Replacement Considerations

Direct substitutes require matching the 16.7 mm inner diameter and nanocrystal material type. Verify that alternative components meet the same 120°C temperature rating and provide comparable impedance characteristics at 300 MHz to ensure equivalent noise suppression performance.
