28R1339-000

Overview

The 28R1339-000 is a split snap-on ferrite core manufactured by Laird-Signal Integrity Products, designed for broadband EMI filtering on cables and wires. It features a lightweight plastic case housing solid ferrite material. The component exhibits an impedance of 152 Ohms at 100 MHz. Its physical dimensions include an inner diameter of 1.165 inches wide by 0.059 inches high (29.58mm x 1.50mm) and an outer diameter of 1.339 inches wide by 0.305 inches high (34.00mm x 7.75mm), with a total length of unspecified in the provided text but implied by the core structure.

Feature Summary

• Split snap-on design allows installation onto existing cables without disconnection
• Lightweight plastic case construction for easy handling
• Solid ferrite material provides broadband electromagnetic interference suppression

Applications

• Suppression of unintended signals on cables
• Filtering of signals being emitted from wires
• Broadband EMI filtering applications

Procurement Notes

Verify the specific impedance value and dimensional tolerances against the official manufacturer datasheet before integration. Confirm that the split-core geometry matches the target cable diameter to ensure proper magnetic coupling and effective noise attenuation performance.

Selection Notes

Select this component when retrofitting EMI suppression onto existing wiring harnesses is required. The split design facilitates assembly without breaking circuit continuity. Ensure the operating environment is compatible with the plastic casing material and that the 152 Ohm impedance profile aligns with the targeted noise frequency spectrum.

Part Context

This part belongs to the cable ferrite category within Laird-Signal Integrity Products' portfolio. It serves as a passive component for signal integrity management, specifically targeting conducted emissions on interconnects. The product is distinct from solid cores or bead filters due to its accessible split mechanism.
