ESD-R-25SH

Overview

The KEMET ESD-R-25SH is a solid, free-hanging ferrite core designed for electromagnetic interference suppression on round cables. Constructed from nickel-zinc (NiZn) material, it features an inner diameter of 15.00mm (0.591 inches), an outer diameter of 25.00mm (0.984 inches), and a length of 12.00mm (0.472 inches). The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 10 MHz.

Feature Summary

• Solid toroidal construction eliminates the need for assembly hardware or snap-on mechanisms.
• Nickel-zinc magnetic material provides effective high-frequency noise attenuation.
• Free-hanging design allows for flexible installation on existing cable assemblies.

Applications

• Suppression of electromagnetic interference on round power and signal cables
• Common-mode noise reduction in electronic equipment wiring
• Cable harness filtering in industrial control systems

Procurement Notes

Verify the specific operating temperature requirements against the -25°C to +85°C rating before procurement. Confirm that the cable diameter falls within the 15.00mm inner diameter specification to ensure proper fit. Check for RoHS compliance status if required by your manufacturing standards. Ensure the frequency range of application aligns with the component's 10 MHz rating.

Selection Notes

Select this model when a non-split, solid ferrite core is required for permanent cable installations. The NiZn composition is suitable for higher frequency applications compared to MnZn alternatives. Consider the free-hanging form factor for ease of retrofitting onto cables without disassembly. Verify that the physical dimensions accommodate the available space in the enclosure.

Part Context

This component belongs to the ESD-R series of solid ferrite cores manufactured by KEMET. It is distinct from split-core or snap-on variants like the ESD-SR series, offering a continuous magnetic path. The series is widely used for EMI suppression in various electronic applications requiring robust, passive filtering solutions.

Replacement Considerations

Direct substitutes include other solid NiZn ferrite cores with matching dimensions, such as the ESD-R-25SD, though the latter may have different temperature ratings. Verify compatibility with any alternative part number regarding inner diameter, material composition, and thermal limits.
