28B0138-7

Overview

The Leader Tech Inc. 28B0138-7 is a solid round ferrite bead designed for cable bundle applications. It features an inner diameter of 0.9 mm (0.034 inches) and an outer length of 14.0 mm (0.550 inches). The component utilizes Material 28, providing an impedance of 234 Ohms at 100 MHz. It is manufactured by Leader Tech Inc. and complies with RoHS standards.

Feature Summary

• Solid round ferrite construction for direct cable clamping
• High impedance performance using Material 28 composition
• Designed for single cable or small bundle suppression

Applications

• Suppression of high-frequency noise on individual cables
• EMI filtering in compact electronic assemblies
• Cable harness noise reduction in industrial equipment

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the 0.9 mm inner diameter accommodates the target cable insulation thickness without excessive force. Ensure compliance requirements match the project specifications.

Selection Notes

Select this component when a solid, non-split ferrite design is required for permanent installation. The Material 28 formulation offers high impedance suitable for broadband noise suppression. Consider the fixed inner diameter constraint during cable selection to ensure proper fit and magnetic coupling efficiency.

Part Context

This part belongs to the Leader Tech Ferrite Beads category, specifically within the solid round style. It is distinct from snap-on cores or split beads, offering a fixed geometry for consistent magnetic properties. The product line focuses on EMI/RFI suppression components for various industrial and commercial applications.
