MD-40J Frequently Asked Questions (FAQ)
-
CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of 1 W/m-K or higher is suggested to improve heat transfer between the module and the heat sink.
-
To ensure reliable operation in high-vibration environments, CUI recommends securing the module to the PCB using screws or adhesive, and using a conformal coating to protect the module from moisture and contaminants. Additionally, the PCB should be designed to minimize flexure and vibration transmission to the module.
-
The maximum allowable capacitance for the output filter is 10 μF. Exceeding this value may cause instability or oscillation in the converter. CUI recommends using a low-ESR capacitor with a capacitance value of 4.7 μF to 10 μF for optimal performance.
-
Yes, the MD-40J can be used in a redundant or parallel configuration to achieve higher power or redundancy. However, CUI recommends consulting with their application engineers to ensure proper design and implementation to avoid any potential issues or instability.
-
CUI recommends using a fuse with a rating of 5 A to 10 A, depending on the input voltage and current requirements. A slow-blow fuse type is recommended to ensure reliable operation and to prevent nuisance tripping.
