ESD-SR-190736X-R1

Overview

The KEMET ESD-SR-190736X-R1 is a round snap-on ferrite core designed for electromagnetic interference (EMI) suppression. It features a manganese-zinc (Mn-Zn) material composition optimized for high-frequency applications up to 500MHz. The component has an inner diameter of 7mm and external dimensions of 37.4mm length, 19.6mm width, and 20.3mm height. It operates within a temperature range of -25°C to +85°C and complies with RoHS standards.

Feature Summary

• Snap-on design allows for rapid installation on cables without disconnection
• Round shape provides uniform magnetic field distribution around the conductor
• Hinged construction facilitates easy placement over existing wiring harnesses

Applications

• Electromagnetic interference suppression in consumer electronics
• Noise reduction in automotive cable assemblies
• Signal integrity enhancement in industrial control systems

Procurement Notes

Verify the exact part number suffix against official KEMET documentation to ensure correct material grade and dimensional tolerances. Confirm that the Mn-Zn composition aligns with your specific frequency requirements. Check for RoHS compliance status if operating in regulated regions. Ensure the 7mm inner diameter accommodates the target cable bundle size without excessive clearance.

Selection Notes

Select this component when a round profile is required for uniform noise attenuation around cylindrical cables. The 7mm aperture suits moderate cable diameters. Consider the 500MHz performance limit for high-speed digital lines. Compare with split-core alternatives if frequent access is needed. Verify thermal stability meets the operational environment's maximum temperature constraints.
