ESD-SR-150

Overview

The KEMET ESD-SR-150 is a snap-on ferrite core designed for electromagnetic interference suppression on round cables. It features a single opening with a 7 mm inner diameter to accommodate cable bundles. The component measures 19.6 mm in width, 20.3 mm in height, and 37.4 mm in depth. It provides an impedance of 180 Ω at 25 MHz and 350 Ω at 100 MHz. Constructed from ferrite material, it operates within a temperature range suitable for consumer electronics applications.

Feature Summary

• Snap-on design allows for rapid installation onto existing cable assemblies without disconnection.
• High impedance characteristics effectively suppress electromagnetic interference across specified frequency bands.
• Single-opening geometry accommodates round cables up to the specified inner diameter.

Applications

• Consumer electronics
• Cable assembly EMI suppression

Procurement Notes

Verify the specific impedance requirements against application frequency spectra before procurement. Confirm that the cable bundle diameter fits within the 7 mm inner aperture. Ensure compliance with RoHS standards if required by the end product regulations. Cross-reference the manufacturer part number to distinguish between similar series variants.

Selection Notes

Select this component when high attenuation is required at 100 MHz for round cable configurations. The snap-on form factor is preferred over split cores for speed of assembly. Evaluate the thermal environment to ensure operation remains within standard limits. Compare impedance curves against competing ferrite materials to determine optimal noise reduction performance.

Part Context

This component belongs to the ESD-SR Snap-on Cores series manufactured by KEMET. The series focuses on quick-installation solutions for electromagnetic compatibility. Ferrite rings in this line are engineered for general-purpose noise suppression in electronic interconnects.
