DSC250100L - Panasonic

DSC250100L Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the DSC250100L?
  Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the capacitor. The capacitor should be placed close to the power source and the PCB should have a low impedance path for the high-frequency current.
• How do I ensure the reliability of the DSC250100L in high-temperature applications?
  To ensure reliability, Panasonic recommends following the derating guidelines for temperature and voltage. The capacitor should be operated within the specified temperature range, and the voltage should be derated by 1.25% per degree Celsius above 85°C. Additionally, the capacitor should be stored in a dry environment to prevent moisture absorption.
• What is the equivalent series resistance (ESR) of the DSC250100L?
  The ESR of the DSC250100L is not explicitly stated in the datasheet, but it can be estimated based on the impedance characteristics. According to Panasonic, the ESR is typically around 10-20 mΩ at 100 kHz.
• Can the DSC250100L be used in high-frequency applications above 1 MHz?
  While the DSC250100L is rated for frequencies up to 1 MHz, it can be used in higher-frequency applications with some caution. However, the capacitor's impedance will increase significantly above 1 MHz, and the self-resonant frequency should be considered. Panasonic recommends consulting with their application engineers for specific guidance.
• What is the recommended soldering profile for the DSC250100L?
  Panasonic recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-30 seconds. The soldering process should be done in a nitrogen atmosphere to prevent oxidation.
