RAC03-12SK/SMT-R - RECOM Power

RAC03-12SK/SMT-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  RECOM Power Inc recommends a PCB layout with a large copper area for heat dissipation, and a thermal via under the module to improve heat transfer. A thermal interface material (TIM) can also be used to enhance heat transfer between the module and the heat sink.
• How do I ensure the module's reliability and longevity in high-temperature environments?
  To ensure reliability and longevity, it's essential to operate the module within its specified temperature range (up to 85°C for RAC03-12SK/SMT-R). Additionally, consider using a heat sink, thermal interface material, and ensuring good airflow to keep the module temperature below 80°C.
• What are the recommended input and output capacitors for this module?
  RECOM Power Inc recommends using X7R or X5R ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. For the output, use a capacitor with a voltage rating of at least 1.5 times the output voltage. The capacitor values should be chosen based on the specific application's requirements.
• How do I protect the module from input voltage transients and surges?
  To protect the module from input voltage transients and surges, consider adding a TVS (Transient Voltage Suppressor) diode or a varistor at the input. This will help absorb or clamp voltage spikes and ensure the module operates within its specified input voltage range.
• What is the module's behavior during input voltage brownout or dropout?
  The RAC03-12SK/SMT-R module will typically shut down or enter an undervoltage lockout (UVLO) state during an input voltage brownout or dropout. Once the input voltage returns to a safe level, the module will automatically restart.
