443178281

Overview

Fair-Rite Products Corp. part number 443178281 is a split core ferrite assembly designed for cable applications. It utilizes Material 44, which provides high permeability for effective noise suppression in the lower frequency range. The component features a round snap-on design with an inner diameter of 8.7 mm (0.343 inches). Official specifications indicate an impedance of 252 ohms at 25 MHz and 300 MHz. This hinged construction allows for installation on existing cables without disconnection.

Feature Summary

• Split core snap-on design enables installation on terminated cables
• Material 44 composition optimized for low-frequency noise attenuation
• Round cross-section accommodates standard cable geometries

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction on power supply lines
• Common mode choke application for signal integrity

Procurement Notes

Verify the specific impedance tolerance requirements against the datasheet before ordering. Confirm that the cable diameter falls within the 8.7 mm inner diameter specification to ensure proper mechanical fit. Check for RoHS compliance status if required by your manufacturing standards. Ensure the material selection aligns with the target frequency spectrum of the noise being suppressed.

Selection Notes

Select this part when post-assembly modification is necessary or when continuous loop cores cannot be used. Material 44 is preferred over Material 43 for frequencies below 10 MHz. Compare the physical dimensions against available space constraints. Consider the mechanical retention strength of the snap-fit mechanism for vibration-prone environments.
