ESD-R-19M-H

Overview

The KEMET ESD-R-19M-H is a solid Mn-Zn ferrite toroidal core designed for electromagnetic interference (EMI) suppression. It features an inner diameter of 7.7 mm, an outer diameter of 22.0 mm, and a length of 14.0 mm. The component operates within a temperature range of -40°C to +125°C and provides effective noise attenuation at frequencies up to 10 MHz.

Feature Summary

• Solid construction ensures mechanical stability during cable installation
• Manganese-zinc material composition optimized for low-frequency EMI suppression
• Free-hanging design allows flexible mounting on round cables

Applications

• Suppression of electromagnetic interference on power supply cables
• Noise reduction in automotive wiring harnesses
• Signal integrity enhancement in industrial control equipment

Procurement Notes

Verify the specific suffix 'H' against official KEMET documentation to confirm dimensional tolerances and material specifications. Ensure the requested quantity matches standard packaging formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to finalizing procurement orders.

Selection Notes

Select this component when targeting low-frequency noise attenuation below 10 MHz. The Mn-Zn material offers higher permeability than Ni-Zn variants, making it suitable for power line filtering. Verify that the cable diameter fits within the 7.7 mm inner diameter constraint before integration into the assembly design.

Part Context

This part belongs to the KEMET ESD-R-H series of commercial-grade EMI cores. The series provides standardized dimensions for common cable sizes. The ESD-R-19M-H specifically utilizes manganese-zinc ferrite, distinguishing it from nickel-zinc alternatives in the same physical footprint family.

Replacement Considerations

Cross-reference with ESD-R-19N-H for nickel-zinc applications requiring higher frequency performance. Verify compatibility with ESD-R-19D if legacy designs require equivalent physical dimensions.
