CS25B4000

Overview

The CS25B4000 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. Designed for electromagnetic interference suppression, this component features a square shape with an inside diameter of 19.6 mm and an outside length of 49.8 mm. It provides an impedance of 590 Ohms at 700 MHz. The unit is RoHS compliant and utilizes a snap-spring grip mechanism to secure cables.

Feature Summary

• Hinged design allows installation on existing cable assemblies without disconnection
• Provides high impedance attenuation in the 100 MHz to 1 GHz frequency range
• Snap-spring grip secures the core around cables of varying diameters

Applications

• Suppression of EMI/RFI noise on interconnect cables
• Shielding of electronic enclosure wiring harnesses
• Circuit board interface cable noise reduction

Procurement Notes

Verify the specific part number suffix against official Leader Tech documentation to confirm exact impedance characteristics and physical dimensions. Ensure the selected variant matches the required cable diameter range for effective clamping. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select based on the target cable diameter to ensure proper fit within the 19.6 mm internal dimension. Consider the operating frequency range, as peak attenuation occurs near 700 MHz. Verify that the hinged mechanical design accommodates the spatial constraints of the installation environment compared to sleeve-type alternatives.

Part Context

Leader Tech Inc. specializes in EMI shielding solutions for circuit boards and enclosures. This ferrite core belongs to their line of clamp-on components designed for rapid deployment on interconnect cables. The product series offers various impedance values and sizes to address different noise frequencies and cable geometries.

Replacement Considerations

Cross-reference with other Leader Tech hinged ferrite cores such as CS25B1500 or CS25B2032 if dimensional or impedance requirements differ. Ensure substitute parts maintain the same hinged mechanism and voltage ratings.
