Accu-L®
SMD High-Q RF Inductor
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.
FEATURES
• High Q
• RF Power Capability
• High SRF
• Low DC Resistance
• Ultra-Tight Tolerance on Inductance
• Standard 0603 and 0805 Chip Size
• Low Profile
• Rugged Construction
• Taped and Reeled
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.
APPLICATIONS
• Mobile Communications
• Satellite TV Receivers
• GPS
• Vehicle Locations Systems
• Filters
• Matching Networks
