Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-TK1E681AM and how do they affect design selection?
The EEE-TK1E681AM offers 680 µF capacitance with a 25 V maximum voltage rating, making it appropriate for bulk energy storage on 12 V, 15 V, and lower rails in power converters. Designers typically select 25 V rated capacitors on 12 V rails to maintain a 2x derating margin for long-term reliability.
Which power supply topologies benefit most from the 680 µF EEE-TK1E681AM output capacitor?
Buck converters, linear regulators, and server voltage regulator modules benefit most from the 680 µF capacitance of EEE-TK1E681AM for output ripple attenuation. At switching frequencies of 100 kHz to 500 kHz, 680 µF capacitance significantly reduces output voltage ripple to below 50 mV in typical designs.
How does the Panasonic TK SMD package of EEE-TK1E681AM compare to through-hole electrolytic capacitors for PCB assembly?
The TK SMD package eliminates through-hole drilling and allows reflow soldering at up to 260°C, reducing PCB manufacturing steps compared to leaded through-hole capacitors. The SMD form factor also enables tighter component placement, supporting board designs with less than 5 mm component-free zones around the capacitor.
