Features
Applications
l Ultra-compact LC block filters based on 4mm square coil
units. Suitable for surface mounting.
l Developed for use in the increasingly compact world of
video equipment.
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.
