Lundahl Video transformer, LL1575

Video Isolation Transformer LL1575

LL1575 is a high bandwidth video isolation transformer for CCTV (closed circuit television). Due to the very wide bandwidth required in CCTV applications, the LL1575 is wound with a special, bifilar winding technique and uses our unique amorphous strip core.
