Nichicon recommends a PCB layout with a large copper area for the capacitor pads, and a short and wide connection to the capacitor to minimize ESR. A detailed layout guide can be found in Nichicon's application notes.
The LAR2D391MELZ25 is designed for high-frequency applications, but its impedance characteristics may vary depending on the frequency. Nichicon provides a frequency characteristics graph in the datasheet, and recommends consulting their application notes for more information on high-frequency behavior.
The maximum ripple current rating for LAR2D391MELZ25 is not explicitly stated in the datasheet, but it can be calculated using the formula provided in Nichicon's application notes. The calculation takes into account the capacitor's ESR, voltage rating, and operating temperature.
Yes, the LAR2D391MELZ25 is compatible with lead-free soldering processes. Nichicon ensures that their products meet the requirements of the RoHS directive and are compatible with lead-free soldering temperatures up to 260°C.
The shelf life of LAR2D391MELZ25 is 2 years from the date of manufacture, as long as the capacitors are stored in their original packaging and under recommended storage conditions (temperature, humidity, etc.).
