sales representatives or product engineers before ordering.
!Note
CFWLB series ceramic filters are miniature, high
performance ceramic filters composed of piezoelectric
elements connected in a ladder form.
These filters, only 6.3mm high, are 67% the volume
of conventional types.
They are well suited for miniaturizing various kinds
of communications equipment, pocket pagers, pagers,
car radios, cordless telephones and mobile telephones.
1. Miniature and high selectivity
2. A variety of bandwidths are available.
3. Operating temperature range: -20 to +80 (degrees C)

CFWLB455K_series filters are 4-element ceramic filters and miniature versions of CFWLA455K_series.
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.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
