ACCU-L TECHNOLOGY
The Accu-L SMD Inductor is based on thin-film mul ti lay er
The Accu-L inductor is particularly suited for the tele com -
technology. This technology provides a level of control on the
mu ni ca tions industry where there is a continuing trend
elec tri cal and physical characteristics of the com po nent which
towards miniaturization and in creas ing frequencies. The
gives consistent characteristics within a lot and lot-to-lot.
Accu-L inductor meets both the per for mance and tolerance
requirements of present cellular frequencies 450MHz and
The original design provides small size, excellent high-
900MHz and of future fre quen cies, such as 1700MHz,
frequency performance and rugged construction for re li able
1900MHz and 2400MHz.
