ESD-R-38SA

Overview

The KEMET ESD-R-38SA is a cylindrical ferrite core constructed from Manganese-Zinc (Mn-Zn) material, designed for electromagnetic interference suppression on round cables. It features an inner diameter of 17.9 mm and an outer diameter of 42.4 mm. The component has a height of 16 mm and a depth of 17.5 mm. It provides an impedance of 40 ohms at 25 MHz and 80 ohms at 100 MHz. The device operates within a temperature range of -40°C to +110°C and complies with RoHS standards.

Feature Summary

• Constructed from Manganese-Zinc (Mn-Zn) material for effective high-frequency noise attenuation
• Solid toroidal design specifically engineered for clamping around round cables
• Provides defined impedance characteristics across standard test frequencies

Applications

• Electromagnetic interference (EMI) suppression in cable assemblies
• Noise filtering for round cables in electronic equipment
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific suffix 'SA' against official KEMET documentation to confirm dimensional tolerances and material batch specifications. Ensure the selected variant matches the required impedance profile for your frequency range. Confirm compliance status with current regulatory requirements such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when dealing with round cables requiring a 17.9 mm inner diameter clearance. The Mn-Zn composition makes it suitable for lower frequency EMI applications compared to Ni-Zn alternatives. Verify that the operating environment stays within the specified -40°C to +110°C thermal limits to maintain magnetic performance stability.

Part Context

This part belongs to the KEMET ESD-R series of solid toroidal ferrite cores. The series offers various dimensions and material compositions, including both Manganese-Zinc and Nickel-Zn options, to address different EMI suppression needs. These cores are widely used in industrial and consumer electronics for cable noise reduction.

Replacement Considerations

Direct substitutes must match the 17.9 mm inner diameter and Mn-Zn material properties. Check equivalent parts from other manufacturers offering similar cylindrical ferrite cores with comparable impedance values at 25 MHz and 100 MHz.
