... If left open circuit the output voltage will default to 0.75 Vdc. The correct Rtrim value for a specific voltage can be calculated using the following equation: Rtrim = [10.5/(Vo-0.7525)-1] KΩ For example, to set the MX5A-12SA to 3.3 V the following Rtrim resistor must be used: Rtrim = [10.5/(3.3-0.7525)-1] KΩ ...

... MX5A-12SA SMT Non-Isolated Power Module Use in Manufacturing Environment (Continued) Soldering Requirements Bourns recommends the following temperature profile for use on tin lead solder (Sn-Pb Eutectic) and lead free solder. For lead free solder, the maximum temperature during the mounting process should not exceed 245 °C. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. However, the time above 230 ° ...
