ESD-SR-311337X-R1

Overview

The KEMET ESD-SR-311337X-R1 is a snap-on ferrite core from the ESD-SR series, designed for electromagnetic interference suppression. It features a round Mn-Zn construction with an inner diameter of 13 mm and dimensions of 31.5 x 31.6 x 38 mm. The component provides an impedance of 176 Ω at 25 MHz and 321 Ω at 100 MHz. Rated for operation up to 85°C, it supports frequencies up to 500 MHz and complies with RoHS standards.

Feature Summary

Snap-on design enables rapid installation on cables without disconnection
Mn-Zn material composition ensures effective high-frequency noise attenuation
Round geometry accommodates various cable diameters within the aperture limit

Applications

Electrostatic discharge (ESD) protection in consumer electronics
Common mode noise suppression on signal and power cables
EMI mitigation in industrial equipment wiring harnesses

Procurement Notes

Verify the specific suffix 'X-R1' against official KEMET documentation to confirm exact dimensional tolerances and material grade. Ensure the selected variant matches the required operating temperature range of 85°C. Cross-reference the impedance values at 25 MHz and 100 MHz with system requirements to validate performance suitability.

Selection Notes

Select this component when a non-invasive solution for cable noise reduction is required. The 13 mm aperture must accommodate the target cable bundle diameter. Verify that the 85°C thermal rating meets the environmental conditions of the installation site. Confirm compatibility with the specific frequency spectrum of the interference being suppressed.

Part Context

This part belongs to the ESD-SR Snap-on Cores family, which specializes in easy-installation ferrite solutions. These cores are engineered for suppressing electrostatic discharge and common mode noise in compact spaces. The series offers a balance between physical robustness and high-frequency performance for portable and fixed electronic devices.
