REDEXPERT was launched by Würth Elektronik eiSos in 2015 as the world's most accurate AC loss calculation tool for power inductors and has been continuously expanded ever since. The same principle applies to the LED, varistor, and PFC coil product groups, which were recently added to the simulation: REDEXPERT's calculation basis is developed from genuine measurement values obtained by the electronic and electromechanical component manufacturer from real-world circuits. Navigation has been improved in the latest version of the online platform, and numerous application models are available for better component selection. Parameter filters can be applied directly to the component curves.
New features
Varistors are important components for suppressing overvoltages and thus protecting circuits from transient voltage changes. At REDEXPERT, users can utilize a variety of diagrams, such as voltage-over-current or lifetime curves, to practically select varistors based on actual measured values. For LEDs – UV, IR, visible, and white – the luminous flux at a specified DC current can be accurately determined using the measurement data in the diagram and product table. For printed circuit boards, impedance curves at various DC currents can be visualized, and the expected attenuation in the circuit can be determined by considering the system's input and output impedance. A model based on actual measured values is included for calculating AC losses in power inductors, allowing for the precise determination of AC and DC losses for almost any topology.
