3dB bandwidth of "F" signifies the frequency difference (both + and -)
from reference frequency which is nominal center frequency.
p
is expressed "A" or subsequent code, which indicates the
structure/size.
Radial taping is applied to lead type and embossed taping to chip
type. With non-standard products, two-digit alphanumerics indicating
"Individual Specification" are added between "
