10 nH Inductor (Top View)
ACCU-L
®
TECHNOLOGY
The Accu-L
®
SMD Inductor is based on thin-film multilayer
technology. This technology provides a level of control on the
electrical and physical characteristics of the component which
gives consistent characteristics within a lot and lot-to-lot.
The original design provides small size, excellent high-
frequency performance and rugged construction for reliable
automatic assembly.
The Accu-L
®
inductor is particularly suited for the telecom-
munications industry where there is a continuing trend
towards miniaturization and increasing frequencies. The
Accu-L
®
inductor meets both the performance and tolerance
requirements of present cellular frequencies 450MHz and
900MHz and of future frequencies, such as 1700MHz,
1900MHz and 2400MHz.
