ESD-R-12M-H

Overview

The KEMET ESD-R-12M-H is a commercial-grade ferrite toroid core designed for electromagnetic interference (EMI) suppression. It features an inner diameter of 12 mm, an outer diameter of 19 mm, and a height of 9 mm. Constructed from Mn-Zn material, it operates effectively at frequencies around 10 MHz with a maximum operating temperature of +120°C.

Feature Summary

• Snap-on design allows for rapid installation onto cables without disconnection
• Utilizes Mn-Zn ferrite material for effective high-frequency noise attenuation
• Commercial grade construction suitable for standard electronic applications

Applications

• Electromagnetic interference suppression on round cables
• Noise filtering in consumer electronics assemblies
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific suffix 'H' against official KEMET documentation to confirm commercial grade classification and temperature ratings. Ensure the Mn-Zn material composition matches the intended frequency range requirements. Cross-reference dimensions with mechanical constraints before integration.

Selection Notes

Select this component when a snap-on solution is required for cable noise reduction. The 12 mm inner diameter accommodates specific cable bundles. Consider the 120°C thermal limit for environmental compatibility. Mn-Zn material offers optimal performance for the targeted frequency spectrum compared to NiZn alternatives.

Part Context

This part belongs to the ESD-R-H series of EMI cores from KEMET. The series provides solid toroidal designs for general-purpose noise suppression. The ESD-R-12M-H represents a specific size variant within this commercial-grade lineup, balancing physical footprint with magnetic performance.

Replacement Considerations

Consult KEMET datasheets for direct substitutes within the ESD-R-H series. Verify dimensional compatibility and impedance characteristics before substituting with other manufacturers' toroids.
