Panasonic 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 4-layer PCB with a solid ground plane is also recommended.
The EEUED2W470 is designed to operate up to 100 kHz, but its impedance may increase at higher frequencies due to the ESL (Equivalent Series Inductance). Panasonic recommends using a capacitor with a lower ESL value for high-frequency applications.
Panasonic provides a derating curve in the datasheet, which shows that the capacitor's capacitance and voltage rating decrease as the temperature increases. For example, at 125°C, the capacitance is derated to 80% of its nominal value.
Yes, the EEUED2W470 is designed to withstand vibrations up to 10 Hz to 2000 Hz, 10 mm amplitude, and can be used in high-vibration environments. However, it's recommended to follow Panasonic's guidelines for vibration testing and to ensure proper mounting and soldering.
Panasonic recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 2-4°C/second. It's also recommended to use a solder with a melting point above 217°C.
