Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
CERAFILr Plastic Case General Use CFULA_A Series
8.0±0.3
CFULA_A series are high selectivity ceramic filters,
which consist of 4 ceramic elements connected in a
ladder form.
Most suitable for digital communications and cellular
phones because of their improved GDT characteristics.
