28B0137-3

Overview

The Leader Tech Inc. 28B0137-3 is a solid ferrite core designed for electromagnetic interference suppression. It features a material composition optimized for high impedance characteristics, providing a nominal impedance of 153 Ohms. The component has a solid cylindrical geometry with an internal diameter of 1.30 mm, allowing it to be installed directly onto single conductors or small cable bundles. This design facilitates effective noise attenuation in compact electronic assemblies where space constraints limit the use of larger clamp-on cores.

Feature Summary

• Solid construction provides secure mounting on cables without requiring snap-fit mechanisms
• High impedance material composition enhances electromagnetic interference suppression capabilities
• Compact cylindrical form factor enables integration into space-constrained designs

Applications

• Embedded systems requiring localized noise reduction
• Industrial automation signal line filtering
• Consumer electronics power and data cable protection

Procurement Notes

Verify the specific impedance tolerance and frequency response curve against your application requirements before procurement. Confirm that the 1.30 mm inner diameter accommodates the target conductor size with appropriate clearance. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your manufacturing process.

Selection Notes

Select this component when a fixed, non-split ferrite solution is required for permanent installation on small gauge wires. Compare its 153 Ohm impedance rating against competing materials to ensure adequate attenuation at the target noise frequencies. Consider mechanical stability and thermal limits during selection.

Part Context

This part belongs to the ferrite core category from Leader Tech Inc., specifically within their solid core offerings. It is distinct from clamp-on or split-core variants due to its monolithic structure. The product line focuses on providing reliable EMI suppression solutions for various industrial and commercial electronic applications.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, verify that any alternative offers equivalent impedance (153 Ohms) and compatible physical dimensions (1.30 mm ID). Material compatibility and frequency performance must match the original design intent.
