ESD-R-19D

Overview

The KEMET ESD-R-19D is a cylindrical 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 utilizes nickel zinc material composition to provide effective noise attenuation in the frequency range up to 300 MHz. It supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Constructed from nickel zinc material for high-frequency noise suppression
• Cylindrical solid design suitable for round cable applications
• Operates reliably within a wide temperature range of -40°C to +85°C

Applications

• Consumer electronics cable filtering
• General-purpose electromagnetic interference suppression
• Round cable noise attenuation

Procurement Notes

Verify the specific suffix or variant when ordering, as some sources indicate different maximum operating temperatures (e.g., +60°C vs +85°C) for similar part numbers. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 9 mm inner diameter fits the target cable assembly. Ensure the application environment remains within the specified -40°C to +85°C thermal limits. Verify that the nickel zinc material properties align with the required impedance characteristics for the specific noise frequencies encountered in the circuit design.

Part Context

This component belongs to the KEMET ESD-R series of ferrite cores, which are widely used for common-mode noise reduction on cables. The ESD-R series offers various dimensions and materials to accommodate different cable sizes and frequency requirements across industrial and consumer electronic applications.
