MJ1-2502 - Same Sky

MJ1-2502 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  CUI Devices recommends a PCB layout with a solid ground plane, minimal trace lengths, and a decoupling capacitor (e.g., 10nF) between the input and ground pins to minimize noise and ensure stable operation.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, ensure proper heat sinking, keep the device away from heat sources, and consider derating the output current according to the temperature derating curve provided in the datasheet.
• What is the maximum cable length for the output voltage sense lines?
  The maximum cable length for the output voltage sense lines depends on the specific application, but as a general rule, keep the sense lines as short as possible (less than 10 inches) to minimize noise and voltage drops.
• Can I use the MJ1-2502 in a redundant power supply configuration?
  Yes, the MJ1-2502 can be used in a redundant power supply configuration, but ensure that the devices are properly synchronized and that the output voltage sense lines are connected correctly to prevent oscillations and ensure stable operation.
• What is the recommended input capacitor value and type?
  CUI Devices recommends using a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF, depending on the input voltage and ripple requirements, to ensure stable operation and minimize input voltage ripple.
