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.
Turns  ratio:                                                    1 : 1
Dims (Length x Width x Height above PCB (mm)):                   28 x 21 x 14 mm
