About Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors offer the most capacitance for the cost of any common capacitor type, which makes them the standard choice for bulk energy storage and filtering in power circuits. An etched aluminum foil with a thin oxide layer and an electrolyte packs high capacitance into a compact can, at voltages from low-voltage logic rails to high-voltage power stages.
Because they are polarized and their electrolyte ages with heat, the ratings that matter most are capacitance, voltage, ripple current, temperature and rated lifetime. Series differ mainly in how they balance these: long-life series for equipment that runs hot around the clock, low-ESR series for switching power supplies, and automotive-grade and audio-grade series for their specialized requirements. Suntsu sources these capacitors alongside our timing devices and integrated circuits for automotive, industrial and power applications.
Common Applications of Aluminum Electrolytic Capacitors
- Power supply filtering: smoothing rectified DC and holding up output rails in AC-DC and DC-DC converters
- DC link and bulk storage: snap-in and screw-terminal capacitors in inverters, motor drives, UPS and solar systems
- Automotive electronics: automotive-grade series for engine control units, lighting and infotainment
- Audio equipment: audio-grade capacitors for amplifier power supplies and signal coupling
- Industrial and lighting: LED drivers, welding equipment and industrial controls that need high capacitance at high voltage
How to Choose the Right Aluminum Electrolytic Capacitor
Selecting the right aluminum electrolytic capacitor comes down to four key specifications:
Capacitance and Voltage: Match the µF value to your filtering or hold-up needs, and choose a rated voltage with headroom above your circuit’s maximum voltage, including ripple peaks.
Ripple Current and ESR: Make sure the rated ripple current covers the AC current the capacitor will carry. Low-ESR series run cooler in switching power supplies.
Temperature and Lifetime: Lifetime roughly doubles for every 10°C below the rated temperature, so pick a temperature rating and hour rating that suit how hot and how long your product will run.
Mounting Type and Size: Choose SMD or radial lead for board-level designs, snap-in for higher-power boards and screw terminal for chassis-mounted power equipment. Confirm the diameter and height fit your layout.
Check each product’s datasheet to confirm these specs align with your design before ordering.
