Ceramic Filter for Communications Equipment

Series

CFWS455

Resin Molded, High Selectivity Low Profile Type

Ceramic Filter (6-Element)

Ceramic filter CFWS455- series are low profile high

selectivity ceramic filters which use 6 elements in ladder

form. They have the same electric characteristics as

CFW455- series, best suitable to high-class transceivers,

cordless telephones and amateur radios.

!FEATURES

1. Low profile, high selectivity.

2. Available bandwidths B to I as standard.

3. Easily mountable on an any PC boards.

4.Operating temperature range : Y20D to W80D

Storage temperature range : Y40D to W85D

Note : To take best advantage of safety feature of ceramic filters, connect the output to an IF amplifier through a DC cut capacitor.

Avoid directly applying a direct current to output of ceramic filters (between 5 and 2,3,4).
