Country CodeTwo irf3205 inverter circuit diagrams
irf3205 inverter circuit diagram oneIRF is an inverter. The drawings are similar. Put the two IRF pins down, one on the front and one on the back. The two outermost pins are connected to negative elec
The difference between lm393 and lm339
What is LM393?LM393 is a dual voltage comparator integrated circuit. The output load resistance can be connected to any power supply voltage within the allowable power supply voltage range, and is not
TL072 Dual Low Noise JFET Input General Operational Amplifier
Description:The TL07xx JFET input operational amplifier integrates well-matched high-voltage JFET and bipolar transistors in a monolithic integrated circuit. These devices have high slew rate, low inp
1N4148 is a small high-speed switching diode, which switches quickly. It is widely used for unidirectional isolation of circuits with higher signal frequencies, such as communications, computer boards
The function of the capacitor on the graphics card and the reason for the burst? What is the funct
What is the function of the capacitor on the graphics card?There are various types of capacitors on graphics cards, nothing more than filtering, energy storage, bypassing, and decoupling. These are al
What is the invisible killer of integrated circuits?
On August 24, 1998, a professor successfully implanted the chip into his arm. Speaking of chips, everyone knows that chips contain integrated circuits. So, what are integrated circuits afraid of?We ma
Repair of power capacitor failure
The handling of the faulty capacitor should be done after disconnecting the circuit breaker of the capacitor, opening the two isolation switches of the circuit breaker, and discharging the capacitor b
How to judge the quality of a capacitor
The R×10, R×100, and R×1K gears of the multimeter are usually used for test judgment. The red and black test leads are respectively connected to the negative pole of the capacitor (the capacitor needs
What is the difference between 1N4007 and SM4007 series diodes
1N4007 and SM4007 are actually diodes of the same model series. The difference lies in the model prefix, so the final difference is reflected in the package form. 4007 is a commonly used rectifier dio
How to measure whether the Zener diode is leaking?
What is the normal working state of the Zener diode?The Zener diode works in reverse breakdown during normal operation. The normal working state of the Zener diode is related to the diode voltage regu
Sensor fault diagnosis and maintenance technology
1. Diagnose by voltage signal. Before testing the oxygen sensor, the engine must be within the normal operating temperature range.As for the diagnosis method, I wont repeat it here, I believe you are
Solutions for IGBT protection circuit defects
IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (ins
What are the technical characteristics of electrolytic capacitors?
Regarding electrolytic capacitors, I believe you dont know much about it, except that what you have talked about before is only the core material of the product, the electrolyte. So today I want to ta
The difference between tantalum capacitors and ordinary capacitors
The full name of tantalum capacitor is tantalum electrolytic capacitor, which is also a kind of electrolytic capacitor. It uses metal tantalum as the medium. Unlike ordinary electrolytic capacitors, i
IGBT structure diagram_where is the IGBT used?
IGBT, the CPU of power electronics! Small and low-power semiconductor devices play a huge role in many power electronics-related fields. In recent years, IGBT has developed rapidly. Infineon and Japan
