## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Grounding
- Issue : Poor chassis connection compromises common-mode attenuation
- Solution : Implement low-impedance ground path using multiple contact points
Pitfall 2: Input/Output Coupling
- Issue : Unfiltered bypass paths between input and output wiring
- Solution : Maintain minimum 25mm separation between input and output conductors
Pitfall 3: Thermal Overstress
- Issue : Insufficient airflow leading to temperature derating
- Solution : Provide adequate ventilation and consider ambient temperature in enclosure design
### Compatibility Issues with Other Components
Power Supply Integration:
- Ensure compatibility with switching frequency of connected power supplies
- Verify inrush current characteristics don't exceed filter ratings
- Check for resonance issues with power supply input capacitance
System-Level Considerations:
- Motor Drives : May require additional dv/dt filters for high-speed switching
- Sensitive Analog Circuits : Consider supplemental filtering for critical analog sections
- Digital Systems : Evaluate impact on power quality for sensitive digital components
### PCB Layout Recommendations
Placement Strategy:
- Position filter immediately at power entry point
- Maintain direct connection to chassis ground
- Avoid routing sensitive signals near filter components
Routing Guidelines:
- Use wide traces for high-current paths (minimum 2oz copper recommended)
- Implement guard traces around filter components
- Separate analog and digital ground planes with proper star-point connection
Thermal Management:
- Provide adequate copper pour for heat dissipation
- Consider thermal vias for improved heat transfer to inner layers
- Ensure minimum 3mm clearance from heat-sensitive components
