PM28B0736

Overview

The PM28B0736 is a hinged round ferrite core manufactured by Leader Tech Inc. It features an internal diameter of 10.9 mm and an outer diameter of 19.7 mm, with a length of 60.5 mm. The component provides an impedance of 176 Ohms at a test frequency of 100 MHz. Designed for snap-on installation, it serves as a free-hanging cable ferrite bead for EMI suppression.

Feature Summary

• Hinged snap-on design enables rapid installation on cables without disconnection
• Round geometry accommodates cylindrical wire bundles
• Provides high impedance to suppress electromagnetic interference

Applications

• Cable EMI suppression in electronic assemblies
• Signal line noise filtering
• Power cable interference reduction

Procurement Notes

Verify the exact impedance value and physical dimensions against the official Leader Tech datasheet before integration. Confirm that the hinged mechanism remains secure during operation. Ensure the cable diameter falls within the specified 10.9 mm inner diameter range to guarantee proper fit and magnetic coupling effectiveness.

Selection Notes

Select this part when a reusable, snap-on ferrite solution is required for round cables. The 176 Ohm impedance at 100 MHz indicates suitability for specific high-frequency noise profiles. Compare the 10.9 mm ID against existing cable bundles to ensure mechanical compatibility without excessive strain on the connector or insulation.

Part Context

This component belongs to the Leader Tech cable ferrite category, specifically designed as a large bead type. It utilizes a hinged construction to facilitate easy mounting on pre-assembled wiring harnesses, distinguishing it from split-core clamps that require adhesive or screw fastening methods.

Replacement Considerations

The PM28B0736 is listed as obsolete. Verify availability of active substitutes such as the 28B0736-0, which shares similar dimensional characteristics and manufacturer lineage, ensuring impedance and material properties match the original design requirements.
