JCH1012S12 datasheet by XP Power

JCH1012S12 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  XP Power recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use the JCH1012S12 in a high-vibration environment?
  Yes, the JCH1012S12 is designed to withstand vibrations up to 10G peak acceleration, 10-2000 Hz frequency range, and 1 hour duration per axis. However, it's recommended to consult XP Power's application notes for specific vibration testing and mounting recommendations.
• How do I ensure the module's input filter meets my system's EMI requirements?
  The JCH1012S12 has an internal input filter that meets CISPR 22 Class B and FCC Part 15 Class B emissions standards. However, to ensure compliance with your system's specific EMI requirements, XP Power recommends adding external filtering components and consulting their application notes for guidance.
• What is the maximum cable length recommended for the output cables?
  XP Power recommends keeping the output cable length as short as possible (less than 6 inches) to minimize voltage drops and ensure reliable operation. If longer cables are necessary, consult XP Power's application notes for guidance on cable sizing and voltage drop calculations.
• Can I use the JCH1012S12 in a humid or wet environment?
  The JCH1012S12 has a conformal coating that provides some protection against humidity and moisture. However, it's not designed for immersion or exposure to water. If your application requires operation in a humid or wet environment, consult XP Power's application notes for guidance on environmental protection and sealing recommendations.
