Nichicon recommends a PCB layout with a large copper area for the capacitor pads, and a via connection to the internal GND plane to reduce ESR. A minimum of 2mm clearance around the capacitor is also recommended.
While UFW2A470MPD is a general-purpose aluminum electrolytic capacitor, it is not suitable for high-frequency applications (>100kHz) due to its high ESR and ESL. For high-frequency applications, consider using film capacitors or ceramic capacitors instead.
The UFW2A470MPD is rated for operation up to 105°C, but its capacitance and ESR will degrade with increasing temperature. Nichicon recommends derating the capacitor's voltage and current ratings by 20% for every 10°C above 85°C.
While the UFW2A470MPD meets the basic requirements for automotive applications, it is not AEC-Q200 qualified. For automotive applications, consider using AEC-Q200 qualified capacitors that meet the specific requirements for temperature, vibration, and reliability.
Yes, the UFW2A470MPD can be used in series or parallel configurations, but care must be taken to ensure that the total voltage and current ratings are not exceeded. Additionally, the capacitors should be matched in terms of capacitance, ESR, and ESL to minimize uneven stress and ensure reliable operation.
