TDK-Lambda’s Testing Procedures - Examples:

PROCEDURE: Component Derating PURPOSE: To define the real operational terms of each component WHAT WE DO: Verifying data provided by component suppliers + conducting a series of additional tests

PROCEDURE: Ab Normal PURPOSE: To make sure that a rare fall, if occurs, will have a minor impact on the application WHAT WE DO: Initiated faults - for example, power circuits are disconnected and undergo short

PROCEDURE: E. CAP LIFE PURPOSE: To monitor each and every capacitor in the product WHAT WE DO: Thermal tests; Ripple calculations; exposing capacitors to extreme temperatures in order to predict durability

PROCEDURE: Thermal Shock Test (TST) PURPOSE: To verify functional reliability under severe temperature conditions WHAT WE DO: Exposing each component to cycles of extreme temperatures, either high or low

PROCEDURE: LIFE TEST PURPOSE: The final test that a product undergoes WHAT WE DO: Running the device non-stop for 8 months in a laboratory cabinet under harsh conditions - and taking periodic samples
