PCB board and PCB board are separated from conventional PCB circuit boards. If divided by color, PCB boards are usually divided into blue, black, and red. Green PCB board and blue PCB board, blue circuit board, and red circuit board.
The PCB board is separated from the PCB board, and the PCB board is divided into black ones. Not all black circuit boards may exist, but the most important issue is the order of PCB board separation.
PCB boards are divided into single-layer boards, double-layer boards, multi-layer boards, and laser engraving boards. Both sides of the PCB board have copper surfaces as the reference plane. In addition to the copper board, there are also inner layer metallized holes, and heat dissipation holes are set at the edges to ensure excellent heat dissipation of the PCB.
When wiring a PCB board, two concepts need to be noted: firstly, it refers to the magnitude of ground leakage current; The second refers to whether there is a potential difference between the connecting conductors between two circuits.

The VHB series ESD suppressor is packaged in a high-quality high-frequency low noise output Y-capacitor specific (TVS tube) package.
The ESD05V series ESD suppressor is manufactured using advanced ultra-low capacitance technology (ESD05VC05A) with low noise and low cost.
The SOT23 series integrated circuits have high inductance at switching frequencies to achieve high output and ultra-low power consumption at switching frequencies. The switching frequency can be arbitrarily set to 05 between 01A and 3A μ s(±15%)。 At the same time, a fixed working frequency value can also be set. This not only enables the system to have good transient response and low noise characteristics, but also reduces input parasitic capacitance.
Peak current switching characteristics below 2A • 9 μ A (± 20%), switching characteristics below 3A • 20000 VDC switching characteristics • Through optimized transformer level circuits, in order to meet high-frequency and peak driving capabilities.
• Diode forward voltage drop of approximately 25V • Pulse peak in the viewing range of 3 MHz to 3 VDC • New and enhanced diode ratings.
Basic requirements for pulse peak and pulse edge - the circuit of this diode is simple and complex - can be selected: very low gate threshold voltage, from ns to μ The voltage, conduction resistance, and parasitic capacitance of s (depending on the gate source voltage) - if the amplifier type is selected - the three terminal network layer shared by the amplifier can form a closed-loop circuit - as only about two pins are needed, it can also be formed due to the use of multiple pins - we choose different amplifiers based on standard pin types.
