SURFCOIL® PROFESSIONAL GRADE SMT INDUCTORS AND TRANSFORMERS
Engineering Bulletin SG-890
SMD Directional Coupler: GLSN Series
APPLICATIONS
- RF circuits
- Mobile Radio
- Satellite TV
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.
SPECIFICATIONS
- Operating Temperature Range: -40°C to +125°C
- Soldering Heat Resistance: 230°C, 5 s
