Q:The role of inductance in the circuit
DC: the so-called direct current refers to the DC circuit, the role of inductance is equivalent to a wire, can not play any role
Q:What is inductance effect
An inductive device is called an inductor (inductor, which is generally referred to as an inductor in Chinese), and the inductor is usually a coil, which can gather the magnetic field.
Q:Why use inductance
through DC, AC resistance" refined commentary: in electronic circuits, inductance coil of AC current limiting effect
Q:What is the inductor
An inductor (Inductor) is a device capable of converting electrical energy into magnetic energy.
Q:Laptop power adapter is used to do
the production of 1.8V, 3.3V, 5V and many other groups, such as CPU voltage for the memory component operation
Q:Inductance is the sensor?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
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:The value of the inductance is determined by what
The quality factor of the inductor is related to the DC resistance of the coil conductor, the dielectric loss of the coil frame, and the loss caused by the iron core and the shield.
Q:How to choose the high quality inductor?
. Two inductance coil inductance at the same time, according to the definition of Q value (XL/R) selection of small scale values
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
