Choosing the Right Capacitor
MLCC (Multi-Layer Ceramic)
Best for decoupling and filtering. Small, low cost, excellent high-frequency response. Voltage derating is critical.
Tantalum
Best for bulk capacitance in compact power designs. Higher density, stable vs voltage. Use 50% derating.
Electrolytic
Best for power supply bulk storage. Very high capacitance, limited lifespan, ESR increases with age.
Film Capacitors
Best for high-voltage and audio. Excellent stability, self-healing failure mode.
