TOKO

TYPE 4FW

LC Filters for TV, VCR and Video Camera

TYPE

4FW

Features

l

Ultra-compact LC block filters based on 4mm square coil

units. Suitable for surface mounting.

l

Basic units will take up to 2 built-in capacitors.

l

Adjustable and non-adjustable types available. Up to three

units may be used in combination.

l

Highly adaptable – suitable for highpass, lowpass, and

bandpass filters, delay lines, equalizers, etc.

l

Shield case minimizes interference with other components,

allowing high-density layout.

l

Suitable for surface mounting (reflow soldering).

Low Pass Filters for Video Camera
