Sprague-Goodman: SURFCOIL® Professional Grade SMT Inductors and Transformers

SURFCOIL® PROFESSIONAL GRADE SMT INDUCTORS AND TRANSFORMERS

Engineering Bulletin SG-890

Surface Mount Inductor: GLST Series

APPLICATIONS

Mobile radio
Satellite TV
Decoupling in RF circuits

FEATURES

Flat Design
Suitable for reflow and vapor phase soldering
Molded ferrite bobbin is integral with base
Terminals are formed from the ends of the coil windings, eliminating solder joints between the coil and the terminals which could open from the heat of circuit assembly.
