LC Filters for Video
K7 Series
OUTLINE
The K7 series comprise LC filters used for video
equipment like VCRs and video cameras.
Using a 7mm square coil as the base unit, one to
three coils can be used in conbination in order to
construct any optional filter desired.

FEATURES
1. These are block filters using a 7mm square coil as the base unit.
2. Designing of the low-pass filter, high-pass filter, band-pass filter, equalizer and such is possible.
3 Design latitude is wide, and the single, double and triple type is available to meet the desired characteristics.
4. The coil, which is the base unit, is available as adjusted type and adjustable type, and one to three coils can
be used freely in any combination.
5. All the 7mm square base coils are provided with shielding cases. Resin cases are used to achieve double
and triple construction.
6. Type K7, K17 and K25 capable of selfcontaining two capacitors and K17-A and K25-A capable of self-
containing 1 capacitor are used in accordance with the circuit construction.
