Introduction to RF inductors

RF inductors are used in a wide variety of industry sectors, from consumer products to highly specialized scientific applications. The range of applications for RF inductors includes resonance tuning, impedance matching, filtering, and even damping of high-frequency transients in electronic switching operations. A large market today is their use in wireless devices such as tablets, as well as in new products such as IoT devices. More specialized applications include radar, GPS and test equipment. Würth Elektronik eiSos offers a full range of RF inductors as part of its extensive portfolio of electronic components suitable for a wide range of frequencies and applications. AppNote ANP074 explains the key characteristics of RF inductors, the different types and features of Würth Elektronik's RF inductor series, and their potential applications.
