PAC CSS12 Passive Noise Filter, 12 Amp, Choke And Capacitor Design

It'd be nice if some bit of documentation somewhere said which wire is which since you can't see inside the heatshrink to get a look at the circuit, but guessing that red and black go to the power supply and ground worked out well enough. It does work exactly as advertised, though, so I can't really complain. I did not test it at currents anywhere near 12 A, but judging by the size of the components, it can probably get pretty close to that.

Was bought to stop interference on a reversing camera, although it did stop the image totally disappearing it still had considerable interference. Ended up removing the noise filter and disconnecting the earth from the camera as the problem appears to be due to earth loop interference. Image is now clear and stable.

I am very impressed and satisfied by this product. It works perfectly, you need to understand the schematics and where to put it. I comes between camera and power source and only there. Easy and fast. I recommend it 100%.

Cleared up 95% of the interference I was getting on my screen

I put it on the yellow wire constant power and it totally removed all alternator noise from my car stereo
