Q:What is the difference between the ballast and the adapter
but the ballast is the special power supply of fluorescent lamp (electrical characteristics of fluorescent lamp special)
Q:Linear adapter and switching power adapter
Linear adapter and switching power adapter is also known as linear power supply and switching power supply
Q:Is the inductor inductor
However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.
Q:How to choose the high quality inductor?
The so-called performance parameters generally refers to: inductance, rated current, quality factor and the size of the shape is in line with the requirements, etc.
Q:What is the inductor
. Inductor has a certain inductance, it only hinder the current changes.
Q:Inductance is what concept?
Inductance inductance of the size, mainly depends on the number of coils (turns), winding method, with or without the core and core materials, etc.
Q:Inductance has no direction?
To discuss the situation: in the general filter circuit, the direction is not large; but if used in the PWM output inductance, this direction is too critical.
Q:What is the substitution principle of inductance?
If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current constant when the circuit is disconnected.
Q:How to classify inductors
Fixed inductors are divided into hollow inductors, inductance, iron core inductor, according to its structure and shape of pin mode can be divided into vertical to horizontal axial pin pin inductors
Q:What are the main parameters of inductance?
A quantity of inductance, also known as a physical quantity, which produces self inductance.
We are a focus on the production of switching power supplies and power adapters and other power products for high-tech enterprises. Shenzhen power adapter, power adapter manufacturers, switching power adapter, switching power supply manufacturers, charger manufacturers, USB power adapter, 12V power adapter
