Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
CERAFILr Plastic Case General Use CFWLA Series
Ceramic filter CFWLA 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 (degrees C)
Storage temperature range: -40 to +85 (degrees C)
