Key Parameters for Selecting RF Inductors

July 15, 2020 by Coilcraft

Overview

RF inductor selection involves several key parameters: mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application. Inductance value and current rating are the chief determinants of size; other parameters can then be optimized.

Coilcraft, a global magnetic components manufacturer specializing in inductors and transformers, aids engineers who are looking for products that meet a wide range of requirements.
