SURFCOIL® PROFESSIONAL GRADE SMT INDUCTORS AND TRANSFORMERS
Engineering Bulletin SG-890
Wideband Balun Transformer: 4.5 x 4.5 x 2.8 mm - GLSU Series
APPLICATIONS
- RF circuits
- Mobile radio
- Satellite TV
- Cordless phones
FEATURES
- Compact design
- Suitable for automatic insertion
- For reflow and vapor phase soldering
- Ceramic 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.
