!Note
!Note
The CFWCA series comprises small, high performance,
thin (3.0mm) filters consisting of 6 ceramic elements.
The filters are recommend for pager or hand held
cellular phones.
1. The filters are mountable by automatic placers.
2. The filters can be reflow soldered and withstand
3. They are slim, at only 3.0mm maximum thickness.
4. The filters are wide bandwidth, flat GDT within
5. Operating temperature range : -20 to +80 (degree C)
