Title: 1:1 Isolation transformer needed
Post by: nirvanas silence on April 29, 2004, 11:09:26 PM
I need one with primary and secondary resistances around 500 ohms, and I really can't find one with leads rather than PCB mount.  Anyone know where I can get a few besides radio shack (ick!).

Even if it works, $4 each is a bit too much and their products are junk.

Just curious. Why the need for 500 Ohms?

Mouser sells a line of inexpensive ($1.50-3.00) small signal audio transformers in a variety of windings.
