EMI/RFI Suppressing Clips

Some of these suppressors can be mounted for a more secure hold. Mounting them protects the suppressor and the cable from damage due to unwanted movement. It’s also good for managing cable to keep it organized.

Clip these suppressors—also known as ferrite beads and ferrite chokes—around data, USB, video, and sensitive-equipment cable to curb electromagnetic and radio frequency interference. You can attach them anywhere along the cable, even if the cable is already terminated or plugged in.

Suppressors work best when they match or are sized as close as possible to the cable OD.

Rigid—Suppressors with a rigid grip have rigid plastic tabs that firmly hold specific cable ODs and keep the suppressors from sliding out of place. Use them when the position of the suppressor is vital to effectively reduce the interference.

Flexible—Suppressors with a flexible grip have flexible plastic tabs to hold a range of cable ODs. Use them when working with an assortment of cable sizes or if you don’t know the exact OD of a cable. They do not grip as tight as suppressors with a rigid grip. They also may not work as well when used with the smallest cable OD in the range.

Screw Mount—Secure screw-mount suppressors with flat-head screws.

Adhesive Mount—Use the adhesive pad to stick adhesive-mount suppressors in position.

Cable Tie Mount—Thread cable ties through the loops on the cable-tie-mount suppressors to hold them in place.

Press Fit—Push the button tab on the press-fit-mount suppressors into a 0.15" hole to mount them in place.

EMI/RFI-Shielding Cardboard Shipping Boxes

Safely ship circuit boards and other sensitive electronics with two layers of defense against EMI and RFI signals. These boxes have an outer conductive layer that shields your box’s items from electrical noise outside the box, preventing malfunctioning. The inner conductive foam lining dissipates charges inside the box created by handling or movement. The foam also creates a cushion for your items. All meet ANSI/ESD standards for controlling electrostatic discharge and packaging sensitive electronic components.
