CHS4002428 - Cosel

CHS4002428 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Cosel recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure efficient heat dissipation. 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 this module in a high-vibration environment?
  Yes, the CHS4002428 is designed to withstand high-vibration environments. However, it's essential to ensure that the module is properly secured to the PCB and that the PCB is designed to withstand the vibration levels. Cosel recommends following the IPC-9592 standard for vibration testing.
• What is the maximum capacitance derating for this module?
  Cosel recommends derating the output capacitance by 20% to ensure reliable operation and to prevent overvoltage stress on the capacitors.
• Can I use this module in a humid or wet environment?
  The CHS4002428 is designed to operate in a dry environment. If you need to use it in a humid or wet environment, you should consider adding conformal coating or potting to protect the module from moisture. However, this should be done in accordance with Cosel's guidelines and with proper testing to ensure reliability.
• What is the recommended input fuse rating for this module?
  Cosel recommends using a fuse with a rating of 5A to 10A, depending on the input voltage and current requirements. The fuse should be able to handle the maximum input current and voltage of the module.
