## 2. Design Considerations
### Common Design Pitfalls and Solutions
DC Bias Voltage Effects
- Problem : Capacitance reduction under DC bias can affect circuit performance
- Solution : Select higher voltage rating (50V) or use multiple capacitors in parallel
- Verification : Always measure capacitance under actual operating conditions
Temperature Dependency
- Problem : X7R dielectric shows ±15% capacitance variation across temperature range
- Solution : Use C0G/NP0 capacitors for critical temperature-sensitive applications
- Mitigation : Design circuits with sufficient margin for capacitance tolerance
Mechanical Stress Issues
- Problem : Board flexure can cause capacitance changes or cracking
- Solution : Avoid placement near board edges or mounting holes
- Prevention : Use proper soldering profiles and avoid mechanical stress during assembly
### Compatibility Issues with Other Components
Mixed Dielectric Systems
- Avoid mixing X7R with Y5V/Z5U capacitors in temperature-sensitive circuits
- Ensure consistent dielectric characteristics in matched capacitor pairs
High-Frequency Circuit Interactions
- Parasitic inductance can create resonance with other components
- Consider self-resonant frequency when designing filter networks
- Account for PCB trace inductance in high-speed designs
