Product Overview

The 2643102002 is a Round Cable EMI Suppression Core made of 43-grade material. It is controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%. The actual DC H field in the application is this value of H times the actual NI (ampere-turn) product.

FAIR-RITE - 2643102002 - FERRITE CORE, CYLINDRICAL, 235OHM/100MHZ, 300MHZ 5 5 1 1
X-10 signal on 120KHZ, isolator/filter I fabricated a filter / isolator to isolate a 120Khz X-10 carrier that is used to send digital commands via a homes power distribution wiring, for home automation control. Specs on this component did not show high attenuation at 120Khz, however I had several on had and proceeded with a tryout. I needed to pass up to 20 amps on a 120 volt circuit, but isolate the 120Khz signal from the power line noise filtering within the appliance as it was coupling most of the 120Khz signal to nuetral (GND). I found that 3 to 4 turns of a 12AWG cable was initially suffcient , but ended up looping 7 turns of 12AWG through this cylindrical part. It could allso be used to isolate "device" generated noise from the power line that may otherwise interfere with the home automation signaling. Most applications would not require as large as 12AWG, so additional turns could be wound for greater attenuation. It performed great at isolating the 120Khz while passing the 60Hz power without noticible loss. No appreciable heat was noticed at the ferrite component from the 60Hz current draw passing through the ferrite inductor. Also, I suspect this series inductive component could be beneficial in dampening of spike components from lightning as an added benefit. This product allowed for a simple and safe and cost effective soloution to be implemented quickly with allmost no failure modes to be had and no complex assembly. Win - win situation. August 10, 2011
