UPS1E471MPD - Nichicon

UPS1E471MPD Frequently Asked Questions (FAQs)

• What is the recommended derating for this capacitor?
  Nichicon recommends derating the voltage rating of the UPS1E471MPD by 10-20% to ensure reliable operation and to account for any voltage spikes or surges in the circuit.
• How does the capacitor's ESR affect its performance?
  The Equivalent Series Resistance (ESR) of the UPS1E471MPD affects its performance by increasing the overall impedance of the capacitor, which can lead to reduced filtering effectiveness and increased heat generation. Nichicon's datasheet provides ESR values at different frequencies to help designers optimize their circuits.
• Can I use this capacitor in a high-temperature environment?
  The UPS1E471MPD is rated for operation up to 105°C, but its capacitance and ESR values may change significantly at high temperatures. Nichicon recommends consulting their temperature derating charts to ensure the capacitor meets the required specifications in the target application.
• How do I handle the capacitor's polarity?
  The UPS1E471MPD is a polarized capacitor, and its polarity must be observed to prevent damage or malfunction. The positive leg is marked on the capacitor, and it should be connected to the more positive voltage in the circuit.
• What is the recommended soldering profile for this capacitor?
  Nichicon recommends following the J-STD-020D.1 standard for soldering the UPS1E471MPD, with a peak temperature of 260°C and a dwell time of 10-30 seconds. This ensures reliable solder joints and prevents damage to the capacitor.
