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)):

Pin layout (top view) and winding schematics:

28 x 21 x 14 mm

Spacing between rows of pins:

Weight:

5.08 mm (0.2")

22.86 mm (0.9")

22 g

Rec. PCB hole diameter:

1.5 mm

Static resistance of primary:

Static resistance of secondary :

Signal loss (source 75Ω , load 75Ω)

Primary no-load impedance (300 Hz, 7V rms)

Frequency response

4.5 Ω

0.5 dB

> 3.5 kΩ

(1V p-p sinus. Source 75Ω , load 75Ω):

Isolation between primary and secondary windings:

20 Hz - 11 MHz +0 /- 3 dB

2 kV rms

Suggested connection for galvanic isolation of video signal
