ESD-R-57A-1

Overview

The KEMET ESD-R-57A-1 is a solid manganese zinc (MnZn) ferrite core designed for electromagnetic interference suppression. It features a circular geometry with an inner diameter of 32.40 mm, an outer diameter of 61.00 mm, and a length of 24.00 mm. The component operates at a frequency of 10 MHz and supports a maximum operating temperature of +85°C. It is rated for a maximum DC current of 1 A and complies with RoHS3 standards.

Feature Summary

• Solid MnZn ferrite construction for effective high-frequency noise attenuation
• Free-hanging installation design suitable for round cable wrapping
• RoHS3 compliant manufacturing process

Applications

• Electromagnetic interference suppression on round cables
• Common mode noise filtering in electronic assemblies
• Cable harness protection in industrial equipment

Procurement Notes

Verify the specific suffix 'A-1' to ensure correct MnZn material composition and dimensional accuracy. Confirm RoHS3 compliance status if required by project specifications. Check standard lead times as availability may vary. Ensure the selected distributor provides official datasheets for final technical validation before integration.

Selection Notes

Select this component when a solid toroidal core with a 32.40 mm inner diameter is required for round cable applications. The MnZn material is appropriate for frequencies around 10 MHz. Consider thermal limits of +85°C during system design. Verify that the 1 A current rating meets the operational requirements of the target cable assembly.

Part Context

This part belongs to the KEMET ESD-R series of commercial grade EMI cores. The series offers various sizes and materials to address different cable diameters and frequency ranges. The ESD-R-57A-1 specifically utilizes MnZn material, distinguishing it from NiZn variants like the ESD-R-57D which offer different magnetic properties.

Replacement Considerations

The ESD-R-57D is a similar size but uses NiZn material and has different dimensions (ID 36.00mm, OD 57.00mm). Direct substitution requires verifying dimensional fit and magnetic performance differences between MnZn and NiZn materials.
