General Specifications
Feature Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions. See the Feature Descriptions section for additional information.
* These are manufacturing test limits. In some situations, results may differ.
Solder, Cleaning, and Drying Considerations
Post solder cleaning is usually the final circuit-board assembly process prior to electrical testing. The result of inad-
equate circuit-board cleaning and drying can affect both the reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on appropriate soldering, cleaning, and drying procedures, refer to
Lineage Power Board-Mounted Power Modules Soldering and Cleaning Application Note (AP97-021EPS).
