CF M455
Miniature High Selectivity Ceramic Filter
for Radio Equipment
CF-M455- 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 60% the volume of
conventional types, They are well suited for miniaturizing
various kinds of communications equipment, pocket pagers,
car radios, cordless telephones and Mobile telephones.
