Small circuit board transformers

Postby michael3065 » Mon Dec 06, 2010 8:15 pm

Before I ask my local yard I was wondering if small circuit board transformers like these pictured have the same "per pound" value as larger ones.

The thing on the top, I believe is an inductor, not a transformer. But most yards buy them at the same price as electric motors.

They usually will be bought at a single price, unless you try to trike up a deal with the boss. The truth is, if you have a big enough inductor/transformer for them to change their price, then you are better of breaking it apart and selling the copper.

The top pic is an inductor. You will see a certain type of inductor called a toroid coil on the power boards of electronic devices. I remove them from the board by cutting them at the board surface and unwinding them from the core = copper wire!
