SURFCOIL® PROFESSIONAL GRADE SMT INDUCTORS AND TRANSFORMERS
Engineering Bulletin SG-890
SMD Current Compensated Toroidal-Core
Choke:
10.8 x 8.8 x 5.5 mm - GLSC Series
APPLICATIONS
- Pulse Transformers
- Electrical Isolation
- Voltage Converter
- RF Transformers
- Filtering for switching mode power supplies
FEATURES
- Toroidal core
- Compact design
- Suitable for automatic insertion
- For reflow and vapor phase soldering
- 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
| Inductance of each winding at 1 kHz (µH) (+30%, -40%) |
Rated Current (A) max |
DC Resistance (20°C) Typical (milliohms) |
