ESD-R-38SR

Overview

The KEMET ESD-R-38SR is a solid free-hanging ferrite core designed for round cable noise suppression. It features an inner diameter of 19.00 mm (0.748 inches) and an outer diameter of 38.00 mm (1.496 inches). The component has a length of 12.70 mm (0.500 inches). This toroidal core operates effectively at frequencies up to 300 MHz, providing impedance characteristics suitable for electromagnetic interference mitigation in electronic assemblies.

Feature Summary

• Solid toroidal construction for secure mounting on round cables
• Free-hanging design allows installation without additional hardware
• Optimized for high-frequency noise attenuation

Applications

• Electromagnetic interference suppression in consumer electronics
• Noise filtering for power and signal cables
• Cable assembly protection in industrial equipment

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESD-R-38SR-P may exist with different dimensional tolerances or material compositions. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected part matches the required inner diameter specifications for the target cable bundle to maintain effective magnetic coupling and physical fitment during assembly processes.

Selection Notes

Select this component based on the required cable diameter compatibility, specifically verifying that the conductor bundle fits within the 19.00 mm inner diameter aperture. Evaluate the frequency spectrum of the interference source against the core's impedance profile to ensure adequate attenuation. Consider the mechanical constraints of the enclosure to accommodate the 38.00 mm outer diameter and 12.70 mm length dimensions without interference from adjacent components.

Part Context

This component belongs to the ESD-R-SR series of snap-on and free-hanging ferrite cores manufactured by KEMET. These cores are engineered for rapid deployment in cable management systems where space constraints preclude the use of larger clamp-style cores. The series provides standardized dimensions to facilitate consistent design practices across various electronic product lines requiring passive EMI mitigation solutions.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model were not identified in available documentation. Verify dimensional equivalence if considering alternative manufacturers, particularly regarding the 19.00 mm inner diameter and 38.00 mm outer diameter constraints.
