CHS3002428 - Cosel

CHS3002428 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 the CHS3002428 in a high-vibration environment?
  Yes, the CHS3002428 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 rigid enough to prevent flexing or resonance that could affect the module's performance.
• What is the maximum capacitance derating for the input capacitors?
  Cosel recommends derating the input capacitors by 50% to ensure reliable operation. This means that if the datasheet specifies a 100uF input capacitor, you should use a 50uF capacitor instead.
• Can I use the CHS3002428 in a high-altitude application?
  Yes, the CHS3002428 is designed to operate up to 5,000 meters (16,400 feet) above sea level. However, it's essential to consider the derating of the module's power rating and efficiency at high altitudes.
• What is the recommended input fuse rating for the CHS3002428?
  Cosel recommends using a fuse with a rating of 5A to 10A, depending on the specific application and input voltage. The fuse should be able to handle the maximum inrush current of the module.
