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
