ESD-R-19SD

Overview

The KEMET ESD-R-19SD is a solid free-hanging ferrite core designed for electromagnetic interference suppression on round cables. It features an inner diameter of 10.00 mm, an outer diameter of 18.50 mm, and a length of 10.00 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 300 MHz. Constructed from nickel-zinc material, it complies with RoHS standards.

Feature Summary

• Solid construction for secure mounting without snap-on mechanisms
• Nickel-zinc composition optimized for high-frequency noise attenuation
• Free-hanging design facilitates installation on various cable types

Applications

• Suppression of electromagnetic interference on round cables
• High-frequency noise filtering in electronic assemblies
• Cable protection in environments requiring operation up to 300 MHz

Procurement Notes

Verify the specific material composition and dimensional tolerances against the official KEMET datasheet prior to procurement. Confirm that the operating temperature range of -25°C to +85°C meets the environmental requirements of the target application. Ensure compliance with relevant regulatory standards such as RoHS for the intended market.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable attachment. The 10 mm inner diameter accommodates specific cable gauges, while the nickel-zinc material provides effective attenuation at higher frequencies compared to manganese-zinc alternatives. Consider the free-hanging form factor for applications where snap-on cores are unsuitable.

Part Context

This part belongs to the KEMET ESD-R series of ferrite toroids and rings. These components are engineered for EMI suppression in electronic circuits. The ESD-R-19SD specifically utilizes a solid geometry distinct from split or snap-on variants, offering a fixed aperture size for consistent magnetic coupling around conductors.

Replacement Considerations

Direct substitutes must match the 10 mm inner diameter, 18.50 mm outer diameter, and 10 mm length. Verify that any replacement uses nickel-zinc material to maintain performance at 300 MHz. Check for identical temperature ratings and RoHS compliance before integration.
