What are thin-film inductors and how can they help with mobile design? Learn about a new inductor from TDK. According to TDK, their newest inductor, the TFM201208ALD, can handle 4% higher currents and 12% lower resistance than conventional products. This is a miniature thin-film power inductor designed with lightweight mobile devices in mind. The unit has a rated inductance of 1.0 µH. In 2017, TDK released the TFM160808ALC series of inductors, themselves an update to the previous TFM series. This newest series continues to demonstrate the industry trend of continually updating components through small improvements that collectively lead to more efficient, specialized components available on the market. As described in Inductor Out, Op-Amp In: An Introduction to Second-Order Active Filters by Robert Keim, inductors are often thought of as “nefarious.” Worse still, unlike resistors and capacitors, inductors are “not particularly compatible with integrated circuit manufacturing techniques.” This mandates more manufacturing steps, higher costs, and decreased reliability. Designers will often avoid using inductors if they can. This often looks like “simulating” inductors ...
