28B1225-000

Overview

The 28B1225-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 140 Ohms at 100 MHz. The component features an inner diameter of 0.750 inches (19.05 mm) and an outer diameter of 1.225 inches (31.12 mm). Its physical length measures 0.627 inches (15.93 mm). This core is designed for cable applications to suppress electromagnetic interference.

Feature Summary

• Solid construction for durable cable mounting
• Free-hanging design allows easy installation on existing cables
• Provides significant high-frequency noise attenuation

Applications

• Cable EMI suppression
• Signal integrity enhancement
• Electromagnetic interference filtering

Procurement Notes

Verify the specific impedance requirement of 140 Ohms at 100 MHz against your system's noise profile. Confirm that the cable diameter falls within the 0.750-inch inner diameter tolerance. Ensure the solid material composition meets your environmental and regulatory standards, such as RoHS compliance, before finalizing procurement.

Selection Notes

Select this component when a robust, non-split ferrite solution is required for larger gauge cables. The 140 Ohm impedance rating targets specific high-frequency noise bands. Consider the free-hanging form factor if snap-on or split-core alternatives are unsuitable for the mechanical constraints of the assembly.

Part Context

This part belongs to the cable ferrites category from Laird-Signal Integrity Products. It complements surface-mount chip beads like the MI series by addressing bulk cable shielding needs. The solid core design distinguishes it from split-core variants used during manufacturing or retrofitting where cable disconnection is not feasible.
