Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment

CERAFILr Plastic Case Group Delay Flat Type CFWLA_Y Series

CFWLA_Y series are high selectivity ceramic filters,

which consist of 6 ceramic elements connected in a

ladder form.

Most suitable for digital communications and mobile

telephones because of their improved GDT

characteristics.

s Features

1. High selectivity.

2. A variety of bandwidths are available.

3. Excellent GDT characteristics are available within

pass bandwidth.

4. Easily mounted on a printed circuit board

5. 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.

(fn) means nominal center frequency 455kHz.

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