ESD-R-47

Overview

The KEMET ESD-R-47 is a solid MnZn ferrite toroid core designed for electromagnetic interference suppression. It features an inner diameter of 25.50 mm, an outer diameter of 48.00 mm, and a length of 16.00 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 100 MHz. Packaged in bulk with a standard quantity of 20 units per package, it serves as a free-hanging cable filter.

Feature Summary

• Solid MnZn ferrite construction for effective EMI suppression
• Round-shaped design suitable for free-hanging installation
• Engineered for high-frequency noise attenuation

Applications

• Cable filtering for electronic equipment
• Electromagnetic interference suppression on wiring harnesses
• Signal integrity protection in industrial electronics

Procurement Notes

Verify the specific material grade and frequency response characteristics against your application requirements before procurement. Confirm that the physical dimensions align with your cable assembly constraints. Ensure compliance with RoHS3 standards if required by your manufacturing process. Check for any specific handling instructions regarding the solid ferrite structure during assembly.

Selection Notes

Select this component when a robust, solid-core solution is needed for broadband noise reduction. Consider the inner diameter to ensure proper fit over the target cables. Evaluate the operating temperature range to confirm suitability for the intended environmental conditions. Compare performance metrics with other ESD-R series variants if space or electrical constraints differ.

Part Context

This part belongs to the KEMET ESD-R series of cable ferrites, which are widely used for common-mode noise suppression. The series offers various sizes and materials to address different frequency ranges and current capacities. The ESD-R-47 specifically utilizes MnZn material, optimized for lower frequency applications compared to NiZn alternatives.

Replacement Considerations

Direct substitutes may include other KEMET ESD-R series parts with similar dimensions, such as ESD-R-47B or ESD-R-47SRH, though material composition and exact dimensions should be verified. Cross-brand replacements require matching inner/outer diameters and material permeability characteristics.
