ESD-SR-160H

Overview

The KEMET ESD-SR-160H is a hinged ferrite snap-on core designed for round cables. It features a nickel-zinc material composition and an internal diameter of 9 mm. The component measures 19.5 mm in width, 19.5 mm in height, and 38.5 mm in length. It provides an impedance of 270 Ω at 100 MHz and 151 Ω at 25 MHz. The device operates within a temperature range up to +85°C and complies with RoHS standards.

Feature Summary

• Hinged snap-on design enables rapid installation on existing cable assemblies without disconnection.
• Nickel-zinc material formulation provides effective high-frequency electromagnetic interference suppression.
• Round cross-section geometry ensures uniform magnetic flux distribution around circular conductors.

Applications

• Suppression of electromagnetic interference on round data and power cables
• Protection of electronic circuits from high-frequency noise disruption
• Signal integrity enhancement in consumer electronics wiring

Procurement Notes

Verify the specific suffix 'H' denotes the hinged configuration distinct from standard snap-on variants. Confirm dimensional tolerances match the 9 mm inner diameter requirement for target cable bundles. Ensure compliance with RoHS directives if required by the end application. Cross-reference impedance specifications against operational frequency ranges to validate performance suitability.

Selection Notes

Select this component when retrofitting cables where opening the loop is impractical due to fixed connectors. The 9 mm aperture accommodates specific cable bundle diameters; verify fitment before integration. Consider the hinged mechanism's durability for repeated access needs. Evaluate thermal constraints against the maximum operating temperature rating of +85°C.

Part Context

This part belongs to the ESD-SR Snap-on Cores series manufactured by KEMET. It serves as an EMI filtering solution for round cables. The product line includes various sizes and materials tailored for different frequency suppression requirements. The hinged variant facilitates maintenance and inspection of protected lines.

Replacement Considerations

Direct substitutes include other KEMET ESD-SR series parts with matching 9 mm inner diameters and similar impedance profiles. Verify that alternative hinged cores maintain comparable physical dimensions for enclosure compatibility. Ensure material composition aligns with required frequency response characteristics.
