As those who’ve followed our insights on inductors already know, we’ve shared numerous articles on common-mode inductors—covering topics such as the careful selection of core materials for common-mode inductor cores, the latest UU‑style common-mode inductors, guidelines for collecting and keeping spare common-mode inductor datasheets, and even a brief overview titled “What Are the Key Characteristics of DC‑Coupled Common-Mode Inductors.” But do you know what types of inductors there are?
As those who’ve followed our insights on inductors already know, we’ve shared numerous articles on common-mode inductors—covering topics such as the careful selection of core materials for common-mode inductor cores, the latest UU‑style common-mode inductors, guidelines for collecting and keeping spare common-mode inductor datasheets, and an overview of the characteristics of DC‑bias‑compensated common-mode inductors. Have you ever considered the different types of inductors?
From the above introduction, we can see that common-mode inductors come in various types, such as toroidal inductors and U‑U‑type inductors. Beyond these, are you familiar with other kinds of common-mode inductors? Below is a summary of the most common types—be sure to read carefully.
Common types of common-mode inductors include: ① surface-mount common-mode inductors.
② Differential-mode inductor
③ Ferrite bead inductor
④GUU common-mode inductor
Do you know what characteristics they all have?
There are two types of chip common-mode inductors: one is the GCDM series, which typically features a relatively low inductance value. The other type is the toroidal‑core chip common-mode inductor; compared with the former, it can achieve much higher inductance values. Moreover, this latter category is well suited for automated machine assembly, significantly reducing labor costs, though at a comparatively higher price.
Common-mode inductors with magnetic cores feature high inductance and high current ratings; during manufacturing, they should be manually inserted.
The GUU common-mode inductor series is a standard type of common-mode inductor; it can achieve a high inductance value, but its current rating is lower than that of toroidal inductors.
A differential-mode inductor is a conventional single‑windings inductor.
