ESD-R-25D-B

Overview

The KEMET ESD-R-25D-B is a solid ferrite core designed for round cables, belonging to the ESD-R series. It features a nickel zinc (NiZn) composition suitable for high-frequency noise suppression. The component has an inner diameter of 13.90mm (0.547 inches), an outer diameter of 29.30mm (1.153 inches), and a length of 15.00mm (0.591 inches). It operates within a temperature range of -25°C to +60°C and supports frequencies up to 300 MHz.

Feature Summary

• Solid construction optimized for clamping onto circular cables
• Nickel zinc material composition for high-frequency performance
• Free-hanging installation capability without additional hardware

Applications

• High-frequency electromagnetic interference suppression on round cables
• Electrostatic discharge protection in electronic assemblies
• Noise filtering for signal and power lines operating above 300 MHz

Procurement Notes

Verify the specific suffix 'B' against official KEMET documentation to confirm dimensional tolerances and material specifications. Ensure the selected variant matches the required inner diameter for the target cable assembly. Cross-reference the RoHS status and lead times with authorized distributors prior to ordering.

Selection Notes

Select this component when a solid, non-split ferrite design is required for permanent cable mounting. The NiZn material is appropriate for applications requiring effective attenuation at higher frequencies compared to MnZn alternatives. Confirm that the physical dimensions accommodate the cable bundle while maintaining sufficient clearance for surrounding components.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. These components are engineered specifically for suppressing electromagnetic interference on round cables. The series offers various material options and sizes to address different frequency ranges and physical constraints in electronic designs.

Replacement Considerations

Direct substitutes include other KEMET ESD-R series parts with matching dimensions, such as the ESD-R-25M-H for MnZn applications or the ESD-R-25D. Verify compatibility by comparing inner diameter, outer diameter, and length specifications.
