Getting Started: An Introduction to Inductor Specifications

There is more to selecting an inductor than determining its nominal inductance value. To ensure an inductor will perform as needed, you need to consider inductance tolerance, current ratings, DCR, maximum operating temperature and efficiency under your specific operating conditions. Whether you are a student or someone new to inductors, this paper provides an overview of the key performance ratings you will need to understand and analyze when specifying RF and Power Inductors.
