Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-1VA470P?
The EEE-1VA470P is rated at 47 µF capacitance and 35 V working voltage with a 20% tolerance. This capacitance-voltage combination is commonly used for output bulk storage in 24 V and 28 V DC power supplies, providing adequate energy reserve during transient load steps.
How does EEE-1VA470P perform in ripple current filtering for switching regulators?
As an aluminum electrolytic SMD capacitor, the EEE-1VA470P handles ripple currents generated by switching regulators at frequencies from DC to hundreds of kilohertz. Its 47 µF capacitance combined with the 35 V rating makes it suitable for output filter stages in 12 V to 24 V buck converters, smoothing voltage ripple to levels below 50 mV peak-to-peak under typical loads.
When should a designer choose EEE-1VA470P over a ceramic capacitor for a 35 V rail?
When PCB cost and capacitance density matter more than ESR, the 47 µF EEE-1VA470P offers substantially higher capacitance than a single 35 V X5R ceramic capacitor, which typically peaks at 10 µF in the same package size. The aluminum electrolytic is the economical choice for bulk output filtering where switching frequency is below 500 kHz and ripple current stays within rated limits.
