REDEXPERT is Würth Elektronik’s advanced online simulation platform designed to streamline the design process of power electronics and EMC filtering. Built on real laboratory measurements—not theoretical models—it enables engineers to select, compare, and simulate components with the highest level of precision.

REDEXPERT covers over 36 component families with more than 20 real-time application simulations, all accessible without registration or installation. It allows interactive comparison of inductors by current vs. inductance, and temperature rise vs. DC current. Its EMI filter designer—a web-first innovation—helps users design custom filters by setting electrical and mechanical parameters to meet application-specific requirements.

Key highlights:

• No installation required; web-based and mobile-friendly
• 6 languages supported, ensuring global accessibility
• Accurate AC/DC loss simulation for inductors in DC/DC converters
• EMI filter simulation tool with recommendations based on user input
• Free sample ordering directly from the platform
• Continuously updated with new modules and application types


By integrating real-world data and intuitive design workflows, REDEXPERT not only accelerates product development but also enhances design confidence for engineers working on power integrity and EMC compliance.
