RECOM recommends a PCB layout with a large copper area connected to the tab of the R-78K9.0-2.0, and a thermal via connecting the top and bottom layers to dissipate heat efficiently.
Yes, the R-78K9.0-2.0 is designed to withstand high vibrations and can operate in environments with vibrations up to 10g acceleration.
RECOM recommends using a soldering iron with a temperature of 350°C to 380°C, and a soldering time of 2-3 seconds. The component should be soldered to the PCB using a solder with a melting point of 220°C to 240°C.
RECOM recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, and a voltage rating of 25V or higher, as close to the input pins of the R-78K9.0-2.0 as possible.
Yes, the R-78K9.0-2.0 can be used in a redundant power supply configuration, but it's essential to ensure that the input voltage and current ratings are not exceeded, and that the output voltage is properly monitored and controlled.
