Several circuit protection technologies – including metal-oxide varistors (MOVs), TVS diodes, LED protectors, and fuses – are needed to provide overvoltage, overcurrent, and high-temperature circuit protection for commercial LED lighting systems.To protect LEDs from too much current, you can use a current-limiting resistor in series with the LED.
What is the purpose of using a filter in a circuit?A filter is a circuit capable of passing certain frequencies while attenuating (to reduce or block) other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant frequencies. In the field of electronics, there are many practical applications for […]

Today qihe smt pick and place machine sharing what’s the embossed tape vs paper tape difference
Lunar new year isn’t far off now, and whether you’re celebrating it or not, you may well have started seeing decoration lights starting to appear adorning houses .
In an enhancement mode MOSFET, voltage applied to the gate terminal increases the conductivity of the device.Today qihe smt pick and place machine sharing what is the difference between a transistor and a MOSFET.
The capacitance of a capacitor is affected by the area of the plates, the distance between the plates, and the ability of the dielectric to support electrostatic forces. This post qihe smt pick and place machine explores how varying these parameters affects the capacitance of a capacitor.
Hello .Merry Christmas to everyone. today we will learn about a customer case which qihe engineers worked on last week of operating Smart home appliance control module on the customized modules completed by TVM802B plus mini desktop pick and place machine .
These typical power supply designs contain a large mains transformer (which also provides isolation between the input and output) and a series regulator circuit. The regulator circuit could consist of a single zener diode or a three-terminal linear series regulator to produce the required output voltage.Today qihe smt pick and place machine sharing General design method of switching power supply. ,pick and place machine,,pick and place machine,smt pick and place machine,pick and place machines,pcb handling,led smt machine,used pick and place machine,smt line equipment,qihe,smt machine cost,how pick and place machine works,desktop smt pick and place machine,pick and place machine diy,
Input resistance is a performance indicator used to measure the impact of an amplifier on a signal source. The larger the input resistance, the smaller the current the amplifier draws from the signal smt ,SMT pick and place machine,smt machine,smd machine,
