## 2. Design Considerations
### Common Design Pitfalls and Solutions
Saturation Issues
- Pitfall : Operating near maximum saturation current causing inductance drop
- Solution : Derate current by 20-30% for margin, monitor temperature rise
Thermal Management
- Pitfall : Inadequate thermal relief in PCB design leading to overheating
- Solution : Use thermal vias, ensure proper copper area for heat dissipation
Mechanical Stress
- Pitfall : Board flexure causing mechanical damage to inductor
