Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment

CERAFILr Plastic Case Miniaturized Type CFWLA_A Series

Ceramic filter CFWLA_A series are low profile high

selectivity ceramic filters which use 6 elements in

ladder form.

They are best suitable to high-class transceivers,

cordless telephones and amateur radios.

s Features

1. Low profile, high selectivity.

2. Available bandwidths are B to J as standard.

3. Easily mountable on any PC board.

4. Operating temperature range : -20 to +80 (degree C)

Storage temperature range : -40 to +85 (degree C)

For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic filters.

The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
