CUI 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 should be connected to a heat sink or a thermal management system.
To ensure reliable operation in high-vibration environments, CUI recommends securing the device using a screw or adhesive that meets the specified torque or bonding requirements. Additionally, the PCB should be designed to minimize flexure and vibration transmission to the device.
CUI recommends derating the input voltage by 10% to ensure reliable operation and to account for voltage tolerances. For example, if the rated input voltage is 12V, the maximum allowable voltage derating would be 10.8V.
Yes, the PSK-S5B-12 can be used in a redundant or parallel configuration, but it's essential to ensure that the devices are properly synchronized and that the output voltages are matched to prevent current imbalances. CUI recommends consulting with their application engineers for specific guidance on implementing redundant or parallel configurations.
CUI estimates the MTBF for the PSK-S5B-12 to be around 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F. However, this value may vary depending on the specific application, operating conditions, and environmental factors.
