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.
We specify impedance ratios as an output to input ratio where the output (or load) is given first and the input is given second (e.g. 100:50 (2:1) would mean a 100 ohm output and a 50 ohm input; a 25:50 (1:2) would mean a 25 ohm load and a 50 ohm input). Most all products use a 50 ohm input unless otherwise specified.
We have products that are available as kits for the do-it-yourself (DIY) person or fully assembled and tested units for the “Plug & Play” crowd.
Our impedance transformers are available using two different topologies: Binocular cores or toroid cores with multiple turns for increased effectiveness and wide band frequency transformations. We utilize single and multiple core transformers using high order windings when needed to extend product performance.
We rate the power ratings as watts PEP (Peak Envelop Power) with standard duty cycles for various modes. To determine the PEP rating required for your needs, see: Choke & Transformer Power Ratings
