Frequently Asked Questions
What voltage and capacitance ratings does the EEE-TK1K221AM provide?
The EEE-TK1K221AM is rated at 220µF capacitance with an 80V working voltage. This combination makes it suitable for high-voltage bulk storage and output filtering in industrial power supplies and motor drive circuits where stable energy reserve above 50V is required.
Which power supply topologies benefit most from this 220µF 80V electrolytic capacitor?
Boost converters, flyback power supplies, and PFC stages operating at output rails of 48V to 72V benefit significantly from the 220µF 80µF rating. The capacitor's SMD form factor and 80V tolerance allow it to handle transient inrush currents and smooth ripple in high-density board designs.
How does the TK series SMD package affect assembly and board layout for this capacitor?
The TK-series SMD package allows reflow soldering and automated pick-and-place, reducing assembly cost compared to through-hole alternatives. The compact surface-mount footprint supports a board height of approximately 16mm or less, saving vertical clearance in enclosed power modules or rack-mount units with tight thermal budgets.
When would an engineer choose the EEE-TK1K221AM over a film capacitor for a 48V bus filter?
An engineer would select the EEE-TK1K221AM when the application demands 220µF or higher capacitance at 48V to 80V on a budget-constrained BOM, since aluminum electrolytics deliver far higher capacitance per unit volume at this voltage than film types, typically at one-third the cost per µF in similar package sizes.
