HW28B2039

Overview

The HW28B2039 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression. It features a snap-on mechanism for easy installation around cables. The component has an impedance of 410 Ohms at 100 MHz. The inside diameter is approximately 11.00 mm (0.433 inches). The external dimensions are 50.80 mm in width, 43.20 mm in height, and 50.80 mm in length. The core material is classified as type 28.

Feature Summary

• Hinged design allows for quick installation on existing cables without disconnection
• Provides electromagnetic interference shielding with high impedance characteristics
• Free-hanging configuration suitable for various cable routing applications

Applications

• Suppression of common mode noise on data cables
• EMI reduction in electronic equipment interconnects
• Shielding of signal lines in industrial control systems

Procurement Notes

Verify the specific part number suffix to ensure correct impedance and dimensional specifications. Confirm that the hinged mechanism is intact and functional upon receipt. Check for any physical damage to the ferrite material or housing. Ensure compatibility with the target cable diameter before finalizing procurement orders.

Selection Notes

Select this component when a non-invasive EMI solution is required for installed cabling. Consider the 410 Ohm impedance profile for frequency ranges where this attenuation is optimal. Verify that the internal diameter accommodates the cable bundle size. Evaluate space constraints against the external dimensions provided in the datasheet.

Part Context

This ferrite core belongs to the Leader Tech Inc. line of EMI shielding products. The company specializes in magnetic components for circuit boards and enclosures. This specific model utilizes a hinged design distinct from split-core or clamp-on variants. It is part of their broader portfolio of cable management and noise suppression solutions.

Replacement Considerations

Cross-reference with HF28B2039 and HI28B2039 for similar hinged ferrite cores. Verify impedance values and physical dimensions match the original design requirements. Ensure the replacement maintains the same mounting style and material properties for equivalent performance.
