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).
