64 valiant - identify this electrical part?
and unless you listen to AM radio, you don't need any of them.
Well actually that might not be true. Any electronics is (can be) sensitive to RF and pulse noise on a system, so having it filtered is a good thing.
As a now somewhat inactive amateur radio operator, I HATE the modern world and what it has become. What some call the "RF noise floor" has increased tremendously in the last 20 years. This is akin to sitting in a very large room full of people, who start talking, whispering, and then slowly get louder and louder, until you cannot hear the person you are actually trying to talk with.
The FCC is no help at all. There was a so called program that "officially" was supposed to be involved to bring broadband internet to rural areas by transmitting data over ............get this..........power lines.
ANY decent RF engineer knows that idea is pure bullshit. What you are trying to do, there, is to use power lines for an RF feedline which was never designed for the purpose. Sort of like using a garden hose for your natural gas or LP furnace. It just doesn't work.
What "BPL" DID do was radiate all kinds of nasty noise. And the FCC just looked the other way, and no longer does the FCC have the staff, the money, nor the will to enforce much of anything.
So you add up, all the appliances with microprocessors, your washer, dryer, microwave, all the switching power supplies for your cell charger, your ethernet hub and modem, your plasma TV, your this and your that and pretty soon "radio" just doesn't work, anymore.
If you made it through this rant, THE SAME THING occurs in your car electrical system. Various "stuff" makes noise. Any switch, relay, regulator, ECU makes noise. And these caps help filter that out.
