CFUM/CFWM455 Y
Miniature, G.D.T. Flat Type Ceramic Filter
Ceramic filter CFUM/CFWM455-Y series are miniature and
high-performance filters.
These filters, with only 6.3mm high, are 60% the volume of
conventional types (CFUS/CFWS series).
Well suited for miniaturizing the communications equipment,
especially for a cellular phone.
!FEATURES
1. Miniature, flat G.D.T. characteristics.
2. Suitable for a cellular phone.
3. A variety of bandwidth are available.
