Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-1VA220AP and what applications fit these specs?
The EEE-1VA220AP is rated at 22 µF capacitance and 35 V working voltage, making it suitable for bulk decoupling on 5 V, 12 V, and 24 V supply rails in switching power supplies, motor controllers, and industrial control boards. At 22 µF, it provides adequate energy storage for transient load demands in DC-DC converter output stages.
How does the VS series low-ESR characteristic of EEE-1VA220AP improve switching power supply performance?
The VS series construction of the EEE-1VA220AP delivers reduced equivalent series resistance (ESR) compared to standard electrolytic capacitors, which lowers power dissipation and reduces output voltage ripple in switching power supply designs operating at switching frequencies up to several hundred kHz. Lower ESR also improves phase margin in feedback-compensated DC-DC converter control loops, enhancing stability at full load conditions with 22 µF output filtering.
What is the package style of the EEE-1VA220AP and how does it compare to through-hole electrolytic capacitors for PCB assembly?
The EEE-1VA220AP uses a surface mount device (SMD) package, enabling automated pick-and-place and reflow soldering assembly with no through-hole drilling requirements. This reduces PCB fabrication cost and assembly time compared to radial through-hole electrolytic capacitors of the same 22 µF 35 V rating, while maintaining compatibility with standard SMT reflow profiles used in consumer and industrial electronics manufacturing.
