PEM1-S15-S5-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A recommended PCB layout is to keep the input and output capacitors close to the module, and to use a solid ground plane to reduce noise and EMI. Additionally, it's recommended to keep the input and output traces separate to minimize cross-talk.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it's recommended to derate the output power according to the temperature derating curve provided in the datasheet. Additionally, ensure good airflow around the module and avoid blocking the ventilation holes.
• What is the recommended input capacitor type and value?
  A low-ESR ceramic capacitor with a value of 10-22uF is recommended for the input capacitor. This helps to filter out input noise and ensures stable operation.
• How do I protect the module from input voltage transients?
  To protect the module from input voltage transients, it's recommended to add a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. This helps to absorb or clamp voltage spikes and surges.
• What is the maximum cable length for the input and output connections?
  The maximum cable length for the input and output connections depends on the specific application and the type of cable used. As a general guideline, keep the cable length as short as possible (less than 6 inches) to minimize voltage drops and noise.
