JZ500 - Knowles

JZ500 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for JZ500?
  The recommended land pattern for JZ500 is a rectangular pad with a size of 2.5mm x 1.25mm, with a non-solder mask defined (NSMD) pad and a solder mask opening of 2.2mm x 1.0mm.
• How do I handle the JZ500 during assembly to prevent damage?
  Handle the JZ500 by the edges or the body, avoiding touching the terminations or the capacitor body to prevent damage from electrostatic discharge (ESD). Use an ESD wrist strap or mat if possible.
• What is the maximum voltage derating for JZ500?
  The maximum voltage derating for JZ500 is 80% of the rated voltage. For example, if the rated voltage is 50V, the maximum operating voltage should be 40V or less.
• Can I use JZ500 in a high-temperature environment?
  JZ500 is rated for operation up to 125°C. However, the capacitance and ESR may degrade at high temperatures. Consult the datasheet for temperature derating curves and consider using a higher temperature-rated capacitor if necessary.
• How do I determine the equivalent series resistance (ESR) of JZ500?
  The ESR of JZ500 can be determined by measuring the impedance of the capacitor at a specific frequency (e.g., 100 kHz) using an impedance analyzer or a network analyzer. The ESR is typically specified in the datasheet as a maximum value.
