ESD-R-17S-1

Overview

The KEMET ESD-R-17S-1 is a solid Nickel Zinc ferrite toroidal core designed for electromagnetic interference (EMI) suppression. It features an inner diameter of 9.4 mm, an outer diameter of 17.7 mm, and an external length of 28.8 mm. The component operates within a temperature range of -25°C to +85°C and is rated for a frequency of 300 MHz. This part belongs to the ESD-R series and is supplied in bulk packaging.

Feature Summary

• Constructed from Nickel Zinc ferrite material for effective high-frequency noise attenuation
• Solid toroidal geometry allows for easy cable threading without disconnection
• Designed specifically for suppressing electromagnetic interference on cables

Applications

• Electromagnetic interference suppression on electronic cables
• Common mode noise reduction in signal lines
• High-frequency noise filtering in consumer electronics

Procurement Notes

Verify current availability status as the component is listed with an end-of-life designation. Confirm that the Nickel Zinc material composition meets specific frequency requirements for the target application. Ensure the physical dimensions are compatible with the cable bundle diameter before integration into the design.

Selection Notes

Select this component when a solid toroid is preferred over snap-on types for permanent cable installations. The Nickel Zinc material offers superior performance at higher frequencies compared to Manganese Zinc alternatives. Verify that the 9.4 mm inner diameter accommodates the maximum cable thickness including insulation.

Part Context

This component is part of the KEMET ESD-R series of solid ferrite rings. Unlike split cores, these require the cable end to be threaded through the center hole during assembly. They provide consistent magnetic properties and are widely used in standard EMI mitigation strategies for wiring harnesses.

Replacement Considerations
