PM28B1625

Overview

The PM28B1625 is a hinged, free-hanging ferrite core manufactured by Leader Tech Inc. It features an inside diameter of 0.311 inches (7.90 mm) and an outside diameter of 0.717 inches (18.20 mm). The component has a length of 2.382 inches (60.50 mm) and provides an impedance of 225 Ohms at 100 MHz.

Feature Summary

• Hinged snap-on design for easy installation on cables
• Free-hanging configuration eliminates need for mounting hardware
• Ferrite material construction for electromagnetic interference suppression

Applications

• Cable noise suppression in electronic assemblies
• EMI filtering for wire harnesses
• Alternative to cable over-molding or shrink tubing

Procurement Notes

Verify the specific impedance value and physical dimensions against your cable diameter requirements before ordering. Confirm RoHS compliance status with the supplier if restricted substances are a constraint for your application. Ensure the hinge mechanism is suitable for the intended installation environment.

Selection Notes

Select this component when a snap-on ferrite solution is preferred over permanent bonding methods. The 0.311-inch inner diameter accommodates cables within the specified range. Consider the 225-ohm impedance at 100 MHz for high-frequency noise attenuation needs.

Part Context

This part belongs to the Leader Tech FerriShield line of EMI suppression components. It is categorized as a clamp-on ferrite core designed to replace traditional cable management methods like taping or tie wraps while providing effective noise reduction.

Replacement Considerations

Check datasheets for compatible ferrite cores with similar impedance curves and inner diameters. Verify that any substitute maintains the hinged mechanical design if field installation is required.
