It is not easy to deal with car noise associated with vehicles. It is a noise generator that drives the car alternator. Grounding and shielding are important. That said, if you desire it to be effective you should loop the wire as many times as you can. In computing the filtering efficiency, square root of the number of turns is used. Thus, up to two turns increases filtration by 4x and up to four turns increases filtering by

Because of the larger inner diameter, I was excited to use only one choke on a speaker cable (using only one choke with four cable wraps instead of two smaller chokes with two Upon opening the package, it was obvious that the product had already been heavily used - it was disappointing. The case is scratched and chipped, and has several dents. In neither the description nor the specification was it stated that it was a used item or used, However, I didn't care about its condition, and decided that its used state wouldn't matter anyway. Sadly, however, this did not do a good job at dampening the extraneous noise caused by This choke worked better than two smaller chokes I had previously used (2 cable wraps each), which also dampened.
My refrigerator has a very large diameter cord, so I needed a choke with a large hole in the center. My experience tells me that I need to wrap the cord around the core four times to eliminate the popping noise. It was easy to do this because the 1" diameter center hole had enough space. With each loop of the choke I passed around, the pop became less loud, and by the fourth loop the fridge was quiet. The purchase was a great buy for me.
That was the exact information I had been About five to six rings will be required for the 1-inch ID hole Try to get 3- 4 turns AC cords. Filtering is proportional to the square of the number of turns, so try to get to at least six turns. The best results are achieved with 6 turns around the object.
The product is useful, it is attractively priced, and the opening is large so that it can handle large.
Around the , you can wrap the wire easily. In the event that the item did actually work, I would give a higher rating. There is a good finish on it as well as the way it holds together. By wrapping the wire around the core and securing it, it is very easy to do. It has not however been enough to eliminate the interference I am experiencing. It hasn't been long enough for the cord to cover the entire core of the object.
I was able to eliminate treadmill interference completely with this product. Just a few wraps of the cord, and the problem is.
In any case, these chokes are well suited to filtering RFI, but double turns through the choke will help to prevent the noise from getting through.
Instruments that use electricity are no longer affected by radio frequency. The one I dropped on the carpet broke when I dropped it from a short distance. This makes it not a long-term solution.
