ESD-R-38C-1

Overview

The KEMET ESD-R-38C-1 is a solid manganese-zinc (MnZn) ferrite toroidal core designed for electromagnetic interference suppression. It features an inner diameter of 17.50 mm, an outer diameter of 39.00 mm, and a length of 14.00 mm. The component operates within a temperature range of -20°C to +85°C and is rated for frequencies up to 10 MHz. It complies with RoHS standards and is classified under ECCN EAR99.

Feature Summary

• Solid construction provides mechanical stability for free-hanging installation on cables.
• Manganese-zinc material composition offers effective high-frequency noise attenuation.

Applications

• Suppression of electromagnetic interference on single-conductor cables
• Common-mode noise reduction in data transmission lines
• EMI filtering for power supply input/output wiring

Procurement Notes

Verify the specific suffix 'C-1' against the manufacturer datasheet to confirm dimensional tolerances and material grade. Ensure the selected variant matches the required cable aperture size of 17.50 mm. Confirm RoHS compliance status and packaging type directly with the supplier or authorized distributor prior to ordering.

Selection Notes

Select this component when a solid, non-split ferrite design is required for permanent cable installations. The 17.50 mm inner diameter dictates the maximum cable bundle size that can pass through the core. Evaluate the MnZn material properties against the specific frequency spectrum of the noise to be suppressed, ensuring compatibility with the 10 MHz operational rating.

Part Context

This part belongs to the KEMET ESD-R series of ferrite toroids. These components are engineered for EMI suppression in electronic assemblies. The series utilizes MnZn ferrite materials optimized for low-frequency noise absorption. The ESD-R-38C-1 represents a specific size configuration within this broader product family.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing cable diameters if considering alternative brands.
