ESD-R-19D-B

Overview

The KEMET ESD-R-19D-B is a cylindrical ferrite core designed for electromagnetic interference suppression. It features a nickel zinc material composition and an internal diameter of 8.8 mm, with an outer diameter of 21.5 mm and a height of 13 mm. The component operates within a temperature range up to +60°C and supports frequencies up to 300 MHz.

Feature Summary

• Cylindrical solid ferrite construction
• Nickel zinc magnetic material
• Free-hanging installation design

Applications

• Consumer electronics EMI suppression
• Round cable noise filtering
• General purpose electromagnetic interference reduction

Procurement Notes

Verify the specific operating temperature limit of +60°C against application requirements, as this differs from standard industrial ratings. Confirm physical dimensions match the target cable bundle size. Check RoHS compliance status in the official datasheet before finalizing procurement specifications.

Selection Notes

Select this model when a compact cylindrical form factor is required for round cables. Ensure the 8.8 mm inner diameter accommodates the cable assembly. Consider the +60°C maximum operating temperature constraint during thermal analysis. Verify that the nickel zinc material properties align with the target frequency spectrum.

Part Context

This component belongs to the KEMET ESD-R series of ferrite cores. These components are engineered for suppressing high-frequency noise on cables. The ESD-R-19D-B variant specifically utilizes a nickel zinc formulation optimized for its designated frequency range and physical constraints.

Replacement Considerations

Cross-reference with other KEMET ESD-R series parts for dimensional compatibility. Verify material composition matches if frequency response characteristics are critical. Ensure substitute components meet the same temperature rating.
