JZ400HV Frequently Asked Questions (FAQs)

  • The recommended land pattern for the JZ400HV can be found in the Knowles Capacitors' application note AN-1101, which provides guidelines for PCB layout and land pattern design to ensure optimal performance and reliability.
  • The JZ400HV is designed for high-frequency applications and exhibits low equivalent series resistance (ESR) and equivalent series inductance (ESL), making it suitable for use in high-frequency circuits up to several hundred MHz. However, the actual performance may vary depending on the specific application and PCB design.
  • The JZ400HV is rated for operation up to 150°C, making it suitable for use in high-temperature environments. However, the capacitor's performance and reliability may degrade at elevated temperatures, and derating may be necessary to ensure long-term reliability.
  • The maximum voltage derating for the JZ400HV is typically 80% of the rated voltage, but this may vary depending on the specific application and operating conditions. It is recommended to consult with Knowles Capacitors' application engineers for specific guidance on voltage derating.
  • Yes, the JZ400HV can be used in DC-blocking applications due to its low DC resistance and high insulation resistance. However, the capacitor's performance and reliability may be affected by the DC voltage and current, and careful consideration should be given to the application's requirements and operating conditions.
