CFWLB_A series ceramic filters are miniature, high

performance ceramic filters composed of piezoelectric

elements connected in a ladder form.

These filters, with only 6.3mm high, are 67% the

volume of conventional types. (CFWLB_A series)

They are well suited for miniaturizing various kinds

of communications equipment, pocket pagers, pagers,

car radios, cordless telephones and mobile telephones.

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.
