!Note
!Note
The CFWCA_Y series comprises small, high performance,
thin (3.0mm) filters consisting of 6 ceramic elements.
The filters are recommend for digital communication
applications and are perfect in hand held cellular
phones.
1. The filters are mountable by automatic placers, and
2. They are slim, at only 3.0mm maximum thickness.
3. The filters are wide bandwidth, flat GDT within
4. Operating temperature range : -20 to +80 (degree C)
CFWCA450KBFY001-R0
For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic filters.
