## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: DC Bias Voltage Effects
- Problem : Significant capacitance reduction (up to 70%) at maximum rated voltage
- Solution : Select higher voltage rating or use multiple capacitors in parallel
Pitfall 2: Mechanical Stress Cracking
- Problem : Board flexure during assembly or operation causing internal cracks
- Solution :
- Place capacitors away from board edges and mounting holes
- Orient capacitors parallel to expected bending forces
- Use stress-relief vias in high-stress areas
Pitfall 3: Thermal Shock Damage
- Problem : Rapid temperature changes during reflow causing delamination
- Solution : Follow recommended reflow profile with maximum ramp rate of 3°C/second
### Compatibility Issues with Other Components
Positive Compatibility:
- Switching Regulators : Excellent pairing with modern buck/boost converters
- Digital ICs : Ideal for decoupling high-speed processors and FPGAs
- RF Amplifiers : Stable performance with GaAs and SiGe RF devices
Potential Issues:
- High-ESR Capacitors : May create resonance issues when combined with electrolytic capacitors
- Precision Analog Circuits : DC bias effects may affect circuit accuracy in sensitive applications
- High-Vibration Systems : Microphonic effects may interfere with sensitive measurement circuits
### PCB Layout Recommendations
Placement Strategy:
- Position decoupling capacitors within 2mm of IC power pins
