We all know that there are many types of inductors, such as SMD inductors, color ring inductors, drum inductors, and so on. Today, let’s talk about the difference between color ring inductors and drum inductors.
Drum inductors are generally composed of magnetic or iron cores, frameworks, winding groups, bushings, packaging materials, etc . We wrap the coil according to the different parameter requirements of the customer and lead out two pins. Drum inductors generally have two pins, but according to customer requirements, some drum inductors also have three pins. The drum inductor is a plug-in inductor. We can distinguish it well from its appearance. It looks like a drum shape. The color ring inductor has obvious shape characteristics. Its two ends are pointed, and the large one is in the middle.

Product features of Drum inductors:

1、 It has high power and high magnetic saturation
2、 It has low impedance, small size, and occupies small space
3、 High Q coefficient and small distributed capacitance
4、 High self resonance frequency; Special guide needle structure, difficult to generate closed loops
5、 PVC or UL heat shrink sleeves are usually used to protect the external I-shaped inductor. It is suitable for computers, power devices, DC/DC conversion, etc.
The color ring inductor has the following five characteristics:
1. Sturdy structure, low cost, and is suitable for automated production
2. Special iron core material, high Q value, self resonant frequency
3. The outer layer is treated with high reliability epoxy resin
4. Large inductance range and automatic plug-in
5. Lead free and environmentally friendly

Color ring inductor usually is used for choke coil, RF applications, peak coil.
In short, the presence of color ring inductance can broaden the sensing range, increase the Q value and SRF value, and extend the service life of the product. The application fields include baivcr, tv.crt, audio, radio Du, disk drives, industrial electronics, LED lighting, smart home, etc.
