An overview of inductance and capacitance and each current| GETWELL

It is easy to understand the difference between chip inductor and chip capacitor, but it is difficult for most people to distinguish, because there are many similarities between chip inductor and chip capacitor. Here's how to tell you about the difference between chip inductor and chip capacitor and the kinds of currents of chip inductor.

The difference between patch inductance and patch capacitance

1. Packaging differences

Generally, if it is installed on a disk, we can see the label above, the unit of capacitance is uf,pf,nf, on the contrary, the unit of inductance is nh,uh,mh.

2. Appearance difference

If it is bulk, we can go through the difference in appearance, the color of the patch inductor is lighter, not very black, and there is no yellowish color, the color of the patch capacitor is generally darker, there are two kinds of black and yellowish, if it is not confirmed, the following method can be used for higher accuracy.

3. Multimeter quiz

The simplest way is to test with a multimeter and test both ends with the turn-on file of the multimeter. If the buzzer rings, it is the inductor, but if you don't want to, it is the capacitance.

Various kinds of current of patch inductor

Patch inductor is a kind of inductor which distinguishes more types of inductors in inductor components, and it is also widely used in daily life, such as sharing bicycles and cars, and some household appliances such as televisions, refrigerators, air conditioners and so on. The use of inductors depends on many parameters, such as inductance, current, scale and so on, but do you know which types of inductors have relatively small current? What kind of inductor has a relatively large current?

Friends who know about inductors all know that chip inductors have the characteristics of small size, high quality, high energy storage, and can be applied to highly automatic placement.

There are many relatively small currents in the chip inductors, such as some ferrite chip inductors, including small volume GCN and GCD chip inductors, the current of these inductors is relatively small current, since it is a small current, then these chip inductors are basically used in a category where the current is not very large, such as relatively small power DC to DC category, or relatively small power supply category.

Patch inductor large current inductor, some are used in step-down above, such as GCDB inductor, its current is relatively large, this kind of inductor is more used in smart home, LED lights, cars and other areas. There are many types of high current patch inductors, such as GCDH, integrated molding inductors and so on. These inductors are relatively large because of the current.
