Imagine you have two metal plates that are very close together, almost touching. If you were to send electricity through them, there would be a tiny amount of electricity that leaks out from the plates and travels through the air between them. This is called "electrical leakage".
The eia class 1 dielectric is a special material that is placed between those two metal plates to stop that electrical leakage. It does this because it is a very strong and sturdy material that doesn't allow electricity to pass through it easily. Think of it like a very thick wall that stops water from leaking through.
This eia class 1 dielectric material is used in electronic devices like cell phones and computers to make sure that the electricity stays exactly where it's supposed to be - on the metal plates and not leaking out all over the place. It's like putting up a strong fence to keep your pets in your backyard instead of them running around the neighborhood.
Overall, the eia class 1 dielectric is a really important material in electronics because it helps keep electrical signals strong and clear, without any interference or leaking.
