MD-40SGK Frequently Asked Questions (FAQs)

CUI Devices recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal pad on the bottom of the device can be used to improve heat dissipation.
To ensure reliable operation in high-vibration environments, CUI Devices recommends securing the device using a screw or adhesive, and using a PCB with a rigid design to minimize flexure. Additionally, conformal coating can be applied to protect the device from environmental factors.
While the datasheet specifies an operating temperature range of -40°C to 85°C, CUI Devices recommends derating the device's power output by 1.5% per degree Celsius above 70°C to ensure reliable operation.
Yes, the MD-40SGK can be used in a redundant or parallel configuration to increase power output or improve reliability. However, it's essential to ensure proper synchronization and current sharing between devices to prevent damage or instability.
CUI Devices recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and output. The capacitors should be rated for the maximum operating voltage and have a temperature rating of at least 105°C.
