Würth Elektronik 2022 3 FOREWORD STEFFEN MUETSCH Head of Product Management EMC & Inductive Solutions JORGE VICTORIA Senior Product Manager EMC Shielding & Thermal Materials In 1892, only 4 years after Heinrich Rudolf Hertz demonstrated experimentally the existence of the electromagnetic waves, the German Parliament issued the first EMC regulation in order to protect telegraph communications from electromagnetic disturbances. Since then, technology and regulation have grown in importance and complexity, and today we cannot live without technology and technology, cannot function properly without EMC and its latest derivations: Signal Integrity (SI) and Power Integrity (PI). Electronic designs today combine or need to coexist with high-speed data lines and processors, 5G, wireless power transfer, near field communication, power inverters, smart battery management… all working in the same electromagnetic environment with a high risk of interference. At Würth Elektonik eiSos (electromagnetic and inductive Solutions) we have been dealing the last 40 years with that environment, facing one by one the impact of every new technology and in switching and communication frequencies. We have developed the right components for every application together with the most important IC manufacturers and EMC certification laboratories worldwide, participating in the regulatory committees and, above all, working day by day with the designers in every version of their prototypes. Education is the best tool to face these new challenges, and this ebook will provide you with a collection of articles dedicated to improving the electromagnetic behavior of your design. Reducing the noise with chip bead ferrites even at high frequencies, optimizing the electromagnetic impact of your switching power supply, or selecting the right capacitor are some examples of the practical content that our engineers want to share with you in the next pages. ■ Education is the best tool to face the new challenges.
