Q:How to select power adapter
The polarity of your notebook symbol is in the negative, the adapter of my pictures is not clear what is marked polarity
Q:How to test the power adapter
if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance
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
Q:What is the power adapter
The power adapter (also called the external power switch power adapter)
Q:Linear adapter and switching power adapter
But the linear power supply EMI is low, but the switching power supply EMI is higher, especially the small power.
Q:Is Australia's power adapter the same as Europe?
Japan is 100V, most of Europe is also 220V, but for example France is 127V and 220V dual voltage.
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:Inductance is the sensor?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"
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),
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.
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
