LGG2G471MELA50 - Nichicon

LGG2G471MELA50 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for LGG2G471MELA50?
  The recommended PCB layout for LGG2G471MELA50 is to have a solid ground plane underneath the capacitor, with vias connecting to the inner layers to reduce inductance. The capacitor pads should be at least 2mm x 2mm in size, with a 1mm gap between them.
• How do I handle the ESR (Equivalent Series Resistance) of LGG2G471MELA50?
  The ESR of LGG2G471MELA50 is typically around 10-20mΩ. To minimize the impact of ESR, use a low-ESR capacitor, and consider using a capacitor with a higher voltage rating to reduce the ESR. Additionally, use a capacitor with a high ripple current rating to handle high-frequency switching.
• What is the derating curve for LGG2G471MELA50?
  The derating curve for LGG2G471MELA50 is typically provided by Nichicon Corporation upon request. However, as a general guideline, the capacitor's capacitance and voltage rating decrease as the temperature increases. For example, at 105°C, the capacitance may be derated by 20-30% and the voltage rating may be derated by 10-20%.
• Can I use LGG2G471MELA50 in a high-vibration environment?
  Yes, LGG2G471MELA50 is designed to withstand high-vibration environments. However, it's essential to ensure that the capacitor is properly mounted and secured to the PCB to prevent mechanical stress. Additionally, consider using a capacitor with a higher vibration rating, such as 20G or higher, depending on the specific application requirements.
• How do I handle the moisture sensitivity of LGG2G471MELA50?
  LGG2G471MELA50 is a moisture-sensitive device. To handle it safely, follow the recommended storage and handling procedures, such as storing the capacitors in a dry, nitrogen-filled environment, and avoiding exposure to high humidity or moisture. Additionally, consider using a moisture-resistant coating or conformal coating to protect the capacitor from moisture.
