BASIC Desktop Computer RFI Kit - AC Powered

This RFI kit is specifically selected to suppress most household computer device RFI problems. It contains a large ferrite ring for AC power supply protection and Snap On ferrite split bead filters selected to eliminate RFI from 1 to 300 MHz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.

The RFI-Desktop kit is meant to be used with a AC powered computer (desktop type) with up to 6 input/output signal lines and an AC power cord line coming into the device. Included are one large ferrite ring filter and six, 3/8” inner diameter snap on split ferrite bead filters for the input/output lines.

Installation is easy. AC power cord through ring filter multiple times and snap on filters on I/O cables nearest computer - problem cured!

For additional devices like a printer and AC powered speakers, consider the Deluxe Desktop RFI Kit with additional filters.

These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
