RAC10E-12SK/277 - RECOM Power

RAC10E-12SK/277 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  The recommended PCB layout for optimal thermal performance involves placing the module on a multi-layer PCB with a large copper area for heat dissipation. The copper area should be connected to a heat sink or a metal plate to further improve heat dissipation.
• How do I ensure the module is properly soldered to the PCB?
  To ensure proper soldering, use a soldering iron with a temperature of 250°C to 270°C. Apply a small amount of solder paste to the PCB pads and place the module on top. Use a reflow oven or a hot air gun to melt the solder paste. Inspect the solder joints for any defects or cold joints.
• What are the precautions to take when handling the module to prevent ESD damage?
  To prevent ESD damage, handle the module in an ESD-protected environment. Wear an ESD wrist strap or use an ESD mat. Avoid touching the module's pins or components. Use ESD-safe packaging and storage materials. Ground yourself before handling the module.
• How do I calculate the power derating for high ambient temperatures?
  To calculate the power derating for high ambient temperatures, use the following formula: Power Derating (%) = (Tambient - 25°C) / (Tmax - 25°C) * 100%. Where Tambient is the ambient temperature and Tmax is the maximum operating temperature specified in the datasheet.
• What are the recommended input and output capacitors for this module?
  The recommended input capacitors are X7R or X5R ceramic capacitors with a voltage rating of 50V or higher. The recommended output capacitors are also X7R or X5R ceramic capacitors with a voltage rating of 25V or higher. The capacitor values depend on the specific application and should be selected based on the output voltage and current requirements.
