Key Features
- 22 µF / 35 V rating with ±20% tolerance in a compact SMD aluminum electrolytic form factor for high-density boards
- Low ESR characteristic extends service life in switching power supply output filter and bulk decoupling roles
- SMD termination compatible with standard reflow soldering at 260°C peak for automated assembly lines
Applications
The EEE-1VA220WR is used as an output filter capacitor in DC-DC converters, as a bulk decoupling reservoir on 24 V and 28 V power rails in industrial equipment, and as a hold-up capacitor in low-power embedded systems. Its 35 V rating provides adequate margin on 24 V bus designs while the 22 µF capacitance smooths ripple current in switching regulator output stages. Engineers use it in consumer electronics, PLC modules, and communication hardware where compact SMD electrolytics are preferred over larger leaded cans.

Frequently Asked Questions
What voltage and capacitance ratings does the EEE-1VA220WR provide for power supply filtering?
The EEE-1VA220WR is rated at 35 V working voltage with a 22 µF capacitance at ±20% tolerance, giving designers adequate margin above typical 24 V or 28 V bus rails while providing sufficient bulk capacitance to smooth switching regulator output ripple at frequencies up to several hundred kHz.
In which circuit positions does the EEE-1VA220WR deliver the best performance compared to ceramic alternatives?
The EEE-1VA220WR outperforms ceramics in low-frequency bulk decoupling and hold-up applications where 22 µF of capacitance is needed at 35 V, because a comparable 22 µF X5R ceramic capacitor at 35 V would occupy a much larger footprint or require a 1210 case with significant DC-bias capacitance derating that reduces effective capacitance to below 10 µF at rated voltage.
How does the SMD package of EEE-1VA220WR simplify manufacturing compared with radial leaded aluminum electrolytics of equivalent capacitance?
The SMD package eliminates through-hole drilling and manual insertion, reducing per-board assembly time by approximately 5–10 seconds per placement, and allows reflow soldering at 260°C peak alongside other surface-mount components in a single-pass process — versus radial leaded capacitors that require a separate wave-solder or hand-solder step adding cost and cycle time.
