Q:How to select power adapter
if you look at symbol and laptops are not the same, it is absolutely impossible.
Q:How to test the power adapter
such as an adapter with 5V and 1A, then it is 5V * 1A = 5W, 5V = 5 and 5W 25 square in Europe, select 5 Euro 5 Watt dummy resistance test adapter performance, such as whether overheating after output voltage fluctuation phenomenon
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 power adapter
, this is because in real life, electronic devices are often not directly use household power
Q:What is the inductance component
Effect: resistance to the flow of DC, high frequency low frequency
Q:What are the two functions of the inductor in the circuit
The role is to impede the flow resistance current power consumption for the logo, change of inductance to impede current is purely to increase the current change
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:What is a power adapter, what is the use of
The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances,
Q:The role of inductance in the circuit
Any of the current in the circuit, will produce a magnetic field, the magnetic flux and the circuit.
Q:Laptop power adapter are AC-DC dual-use
l, a power transformer and rectifier circuit, the working power supply of AC (alternating current standard in China for the exchange of 220V),
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
