|---|---|---|
| Size | 0201 (0.6mm x 0.3mm) | Radial (5mm-50mm) |
| Voltage Range | 4V-1kV | 6.3V-550V |
| Key Strength | Low ESR at high frequencies | High capacitance density |
| Primary Use | Signal filtering | Energy buffering |
Powering Next-Generation Systems
Automotive electronics rely on both capacitor types. MLCCs manage ECU signals while aluminum units stabilize battery outputs. Recent designs integrate hybrid solutions for better thermal management in electric vehicles.
Consumer devices push MLCC innovation further. New high-quality capacitors now achieve 22μF in 0402 packages – 30% smaller than previous models. This miniaturization enables slimmer laptops and AR glasses.
