Ferrite Filter Sleeve ROLINE 6.5 mm — noise suppression choke, white

ROLINE ferrite filter sleeve with a 6.5 mm inner diameter is a compact noise suppression choke designed to reduce electromagnetic interference (EMI/RFI) on cables and wires. The cylindrical white ferrite bead is housed in a nylon clip casing that provides mechanical protection and allows simple slip-on or clip-on assembly, improving signal integrity on power, signal and data lines in computer and peripheral setups.

Advantages

The split design and clip-style nylon casing enable quick retrofitting without disconnecting cables, while the secure clamp prevents accidental detachment and protects the ferrite core from damage. The sleeve is rated with a flame-retardant casing material (UL 94-V-0), ensuring stable performance in typical electronics environments. Its universal inner diameter suits a wide range of single-core cables and cords used for PC, peripherals and general data applications.

Suitable for

• Suppression of high-frequency noise on USB, HDMI, Ethernet and audio cables
• Use on power leads to reduce conducted interference to and from devices
• Retrofit on existing PC, monitor and peripheral cabling
• General cable noise reduction in home and office electronics

Key specifications

• Inner diameter: 6.5 mm
• Form factor: cylindrical split ferrite bead (clip-on/slip-on)
• Color: white casing
• Casing material: nylon, flame-retardant (UL 94-V-0)
• Application: EMI/RFI suppression for single-core data, signal and power cables
• Mechanical protection: enclosed ferrite core with secure clamp

How to use

Open the split casing and position the cable inside the ferrite sleeve so the conductor passes through the ferrite core. Close the clip until it snaps into place; the casing clamps securely around the cable. For improved suppression, place the sleeve as close as possible to the connector or the noise source. Multiple sleeves can be installed along the cable for additional attenuation of high-frequency interference.

Usage recommendations

Use this ferrite filter sleeve on single-core cables with diameters close to 6.5 mm; for thicker multi-conductor or shielded cables consider alternative ferrite sizes or split-core solutions. Avoid forcing cables with significantly larger diameters into the sleeve to prevent casing damage and compromised EMI performance.
