28R1141-010

Overview

The Laird-Signal Integrity Products 28R1141-010 is a solid, free-hanging ferrite core designed for cable filtering applications. It utilizes Material 28 to provide an impedance of 168 Ohms at 100 MHz. The component features a flat design with specific dimensional constraints: an inner dimension of 27.00mm width by 1.50mm height and an outer dimension of 37.00mm width by 8.00mm height. The total length measures 18.26mm (0.719 inches). This part is classified as a cable ferrite intended for electromagnetic interference suppression.

Feature Summary

• Solid construction provides mechanical stability for cable mounting
• Material 28 composition offers high impedance characteristics at 100 MHz
• Free-hanging installation type allows flexible integration onto cables

Applications

• Electromagnetic interference filtering on signal cables
• Common mode noise suppression in electronic assemblies
• Cable protection in industrial control systems

Procurement Notes

Verify the exact material grade and impedance tolerance against the official manufacturer datasheet before procurement. Confirm that the physical dimensions match the receiving equipment's cable clearance requirements. Ensure compliance with relevant environmental regulations such as RoHS status as specified in the latest product documentation. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a flat-profile ferrite core is required for larger diameter cables or specific mounting geometries. The 168 Ohm impedance at 100 MHz suits applications targeting noise frequencies in the high-frequency range. Consider the solid design for durability in environments where vibration resistance is necessary. Evaluate the internal slot dimensions to ensure compatibility with the target cable bundle size.

Part Context

This component belongs to the Laird Signal Integrity Products ferrite core family, specifically engineered for cable-based EMI mitigation. The '28' designation indicates the use of Nickel-Zinc ferrite material known for high resistivity and permeability at higher frequencies. The 'R' series typically denotes specific shape or mounting variations within the product line, distinguishing it from standard cylindrical cores.

Replacement Considerations

Direct substitutes must match the 168 Ohm @ 100 MHz impedance and similar physical dimensions. Verify that alternative parts support the same Material 28 specification for comparable frequency response. Check if the replacement maintains the flat, solid design for identical mounting compatibility.
