SW-312 Frequently Asked Questions (FAQ)

  • A good PCB layout for the SW-312 should prioritize minimal inductance and capacitance in the power supply lines, with a solid ground plane and short, direct connections to the input and output capacitors. Stancor recommends following a star-configuration for the power supply lines and using a common ground point for all components.

  • To ensure the SW-312 operates within its specified temperature range, provide adequate heat sinking and airflow around the device. Stancor recommends mounting the SW-312 on a heat sink with a thermal resistance of 1°C/W or less, and ensuring a minimum of 1 inch of clearance around the device for airflow.

  • Exceeding the maximum input voltage rating of the SW-312 can result in permanent damage to the device, including breakdown of the internal components and potentially leading to a short circuit. It is essential to ensure the input voltage remains within the specified range to prevent damage and ensure reliable operation.

  • While the SW-312 is a high-quality power supply, it is not specifically designed for high-reliability or military applications. Stancor recommends using their military-grade power supplies, such as the M-312, which are designed to meet the stringent requirements of MIL-STD-810 and MIL-STD-883.

  • To troubleshoot common issues with the SW-312, start by verifying the input voltage and ensuring it is within the specified range. Check the output voltage and current to ensure they are within the specified limits. Verify the PCB layout and ensure it meets the recommended guidelines. If issues persist, consult the Stancor application notes and technical support resources for further guidance.
