ESD-R-19

Overview

The KEMET ESD-R-19 is a solid nickel zinc ferrite toroid core designed for electromagnetic interference suppression. It features an inner diameter of 9 mm, an outer diameter of 19 mm, and an external length of 11 mm. The component operates within a temperature range of -25°C to +85°C and supports frequencies up to 300 MHz. It complies with RoHS standards and is supplied in bulk packaging.

Feature Summary

• Solid nickel zinc construction for effective high-frequency noise attenuation
• Free-hanging design suitable for direct cable wrapping applications
• RoHS compliant manufacturing process

Applications

• Electromagnetic interference suppression on round cables
• Common mode noise filtering in electronic assemblies
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific suffix (e.g., D, SRH) against project requirements as dimensions and materials vary across the series. Confirm RoHS compliance status via the official datasheet before integration. Ensure the selected variant matches the required operating temperature range and frequency characteristics for the intended application environment.

Selection Notes

Select based on cable diameter compatibility with the 9 mm inner diameter. Evaluate material properties such as nickel zinc composition for high-frequency performance needs. Consider thermal constraints relative to the specified maximum operating temperature. Verify physical dimensions against spatial limitations in the target assembly.
