ESD-R-220814XH-R1

Overview

The KEMET ESD-R-220814XH-R1 is a toroidal ferrite core designed for electromagnetic interference suppression. It features a Ni-Zn ferromagnetic material composition suitable for high-frequency applications up to 500 MHz. The component has an outer diameter of 22 mm, an inner diameter of 7.7 mm, and a length of 14 mm. It operates within a temperature range of -40°C to +120°C and meets UL94 V-0 flammability standards.

Feature Summary

• High heat resistance with UL94 V-0 rating
• Ni-Zn ferromagnetic material for effective EMI suppression
• Toroidal design for round cable integration

Applications

• Electromagnetic interference suppression for round cables
• High-frequency signal integrity protection
• Automotive electronics harness filtering

Procurement Notes

Verify the specific suffix 'R1' against official KEMET documentation to confirm packaging configuration and reel specifications. Ensure the Ni-Zn material grade matches the required frequency response for the target application. Cross-reference the physical dimensions (22mm OD, 7.7mm ID) with PCB or harness layout constraints to ensure proper fitment during assembly.

Selection Notes

Select this component when high-frequency noise attenuation is required for round cables in environments demanding thermal stability. The Ni-Zn composition offers superior performance at frequencies above 10 MHz compared to Mn-Zn alternatives. Consider the 14mm length and toroidal geometry for space-constrained routing where snap-on installation is preferred over soldered solutions.

Part Context

This part belongs to KEMET's ESD-R-H series of solid ferrite cores. These components are engineered for robust EMI/RFI suppression in automotive and industrial settings. The series utilizes specialized Ni-Zn formulations to maintain consistent impedance characteristics across varying temperatures and frequencies.

Replacement Considerations

Consult KEMET datasheets for direct substitutes within the ESD-R-H series. Verify that any alternative maintains the 22mm OD, 7.7mm ID, and 14mm length dimensions. Ensure the replacement also specifies Ni-Zn material and UL94 V-0 compliance for equivalent thermal and safety performance.
