ESD-SR-120

Overview

The KEMET ESD-SR-120 is a snap-on ferrite core designed for electromagnetic interference suppression on round cables. It features a 6 mm inner diameter and measures 16 mm x 16.4 mm x 33 mm externally. The component exhibits an impedance of 28 Ω at 25 MHz and 100 Ω at 100 MHz. Constructed from ferrite material, it belongs to the ESD-SR Snap-on Cores series and complies with RoHS standards.

Feature Summary

• Snap-on design enables rapid installation without cable disconnection
• Split core structure facilitates easy mounting on existing wiring
• Ferrite composition provides effective high-frequency noise attenuation

Applications

• Consumer electronics cable shielding
• Round cable EMI suppression

Procurement Notes

Verify the specific impedance requirements against application frequency ranges before ordering. Confirm that the 6 mm inner diameter accommodates the target cable bundle size. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the datasheet for thermal operating limits.

Selection Notes

Select this model when a split-core solution is necessary for retrofitting or assembly line efficiency. The 6 mm aperture suits moderate cable diameters. Compare impedance curves at relevant frequencies against alternative materials like NiZn if higher temperature stability is needed. Ensure physical dimensions fit within the available enclosure space.
