ESD-R-22SD

Overview

The KEMET ESD-R-22SD is a nickel-zinc ferrite toroid designed for electromagnetic interference suppression. It features an inner diameter of 15 mm, an outer diameter of 25 mm, and an external length of 12 mm. The component operates within a temperature range up to +85 °C and is rated for frequencies up to 300 MHz.

Feature Summary

• Constructed from nickel-zinc ferrite material for effective high-frequency noise attenuation
• Toroidal geometry supports free-hanging mounting configurations
• Engineered for use as a cable ferrite ring in ESD protection applications

Applications

• Electrostatic discharge (ESD) suppression on cables
• High-frequency noise filtering in electronic assemblies
• EMI reduction in signal and power lines

Procurement Notes

Verify the specific part number against manufacturer documentation to confirm current production status. Note that related variants may be subject to obsolescence or discontinuation notices. Ensure the nickel-zinc composition and dimensional specifications align with the intended electromagnetic interference suppression requirements before procurement.

Selection Notes

Select this component when a 15 mm inner diameter toroid is required for cable wrapping. Confirm that the operating environment remains below +85 °C. Verify compatibility with the target frequency spectrum, as the material is optimized for performance up to 300 MHz. Ensure mechanical clearance allows for the specified outer dimensions.

Part Context

This component belongs to the ESD-R series of ferrite rings manufactured by KEMET. These passive components are utilized primarily for suppressing electromagnetic interference and electrostatic discharge events in wiring harnesses and electronic interconnects without introducing significant impedance to the desired signal path.
