ESD-SR-S57M

Overview

The KEMET ESD-SR-S57M is a ferrite clamp-on core designed for electromagnetic interference (EMI) suppression. It features a split-core snap-on design for rapid installation on cables without disconnection. The component utilizes Mn-Zn ferrite material, rated for operation up to +85°C. Its physical dimensions are 64 mm in length and 24 mm in width. This device is part of the ESD-SR Snap-on Cores series, intended for high-frequency noise reduction in electronic circuits.

Feature Summary

• Snap-on split-core design enables quick installation on existing cables
• Utilizes Mn-Zn ferrite material for effective high-frequency noise attenuation
• Rated for continuous operation at temperatures up to +85°C

Applications

• Electromagnetic interference suppression in electronic circuits
• High-frequency noise reduction on signal and power cables
• Consumer electronics cable protection

Procurement Notes

Verify the specific impedance characteristics and frequency response curves against the official KEMET datasheet for ESD-SR-S57M before integration. Confirm that the internal diameter accommodates the target cable bundle size. Ensure compliance with RoHS standards if required by the end application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a non-invasive, snap-on solution is required for cable shielding. The Mn-Zn material offers high permeability suitable for lower frequency EMI ranges compared to Ni-Zn alternatives. Verify that the 64x24mm form factor fits within the available spatial constraints of the assembly. Consider the +85°C temperature rating relative to the operating environment.

Part Context

This component belongs to the KEMET ESD-SR Snap-on Cores series, which specializes in ferrite clamps for EMI suppression. These cores are engineered for easy retrofitting onto cables. The ESD-SR-S57M specifically uses Mn-Zn material, distinguishing it from Ni-Zn variants like the ESD-SR-160. The series targets consumer electronics and general industrial applications requiring compact noise filtering.
