EEUFC1C472 - Panasonic

EEUFC1C472 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for EEUFC1C472 to minimize ESR?
  Panasonic recommends a PCB layout with a large copper area under the capacitor to reduce ESR. A minimum of 2oz copper thickness is recommended. Additionally, vias should be placed under the capacitor to connect to the internal planes to further reduce ESR.
• How does the EEUFC1C472 behave under high-frequency conditions?
  The EEUFC1C472 is designed to operate at high frequencies, but its impedance increases with frequency. Panasonic provides a impedance vs frequency graph in the datasheet, which shows that the capacitor's impedance increases above 100 kHz. Engineers should consider this when designing high-frequency circuits.
• What is the derating curve for EEUFC1C472 at high temperatures?
  Panasonic provides a derating curve in the datasheet, which shows that the capacitor's capacitance decreases with increasing temperature. Engineers should derate the capacitor's capacitance by 10% for every 10°C above 85°C to ensure reliable operation.
• Can I use EEUFC1C472 in a high-vibration environment?
  Yes, the EEUFC1C472 is designed to withstand vibrations up to 10G (IEC 60068-2-6). However, engineers should ensure that the capacitor is properly mounted and secured to the PCB to prevent mechanical stress.
• What is the recommended soldering profile for EEUFC1C472?
  Panasonic recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-30 seconds. Engineers should ensure that the soldering process does not exceed these parameters to prevent damage to the capacitor.
