28R1953-000

Overview

The 28R1953-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 127 ohms at 100 MHz and utilizes material grade 28. The component features a ribbon design with an internal slot measuring 44.00 mm in width and 1.45 mm in height, while the external dimensions are 49.53 mm in width and 7.62 mm in height.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• High impedance performance at 100 MHz for effective noise suppression
• Wide internal slot accommodates large diameter cables and wiring harnesses

Applications

• Cable and wiring harness noise suppression
• Electromagnetic interference filtering for power lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify that the cable diameter fits within the 44.00 mm x 1.45 mm internal slot dimensions before procurement. Confirm compliance with RoHS3 specifications and REACH status requirements for your specific manufacturing region. Ensure the material grade 28 aligns with your frequency response needs. Check standard lead times as availability may vary by distributor.

Selection Notes

Select this component when high-capacity cable filtering is required due to its wide slot geometry. The 127 ohm impedance at 100 MHz suits applications targeting specific radio frequency noise bands. Consider the solid ribbon form factor for environments where snap-on cores are impractical. Evaluate thermal constraints as the component operates without active cooling mechanisms.

Part Context

This part belongs to the cable ferrite category within Laird-Signal Integrity Products' portfolio. It serves as a passive electromagnetic interference filter component. The product is distinct from bead types or surface-mount solutions, offering a mechanical solution for existing wire bundles rather than integrated circuit protection.
