The flow rate of the glass discharge tube should be greater than the flow capacity of the lightning protection circuit design.
The flow rate of the glass discharge tube should be greater than the flow capacity of the lightning protection circuit design.
resulting in positioning (only for the large plate) or sporadic copper wire loss, but the stripping strength of copper foil near the stripping line will not be abnormal.
Using the principle of electroplating, through the current and voltage control of gold plating on the surface. Anti-oxidation: The use of chemical principles of an anti-oxidation chemical coated on the surface
The capacitor lead should not be too long, especially the high-frequency bypass capacitor should not have a lead.
The following are the main points and points for attention in selection of PTC self-restoring fuses of overcurrent devices arranged by Shuokai Electronics.
Low frequency oscillators are used to reduce energy consumption, such as in battery-powered systems, and high frequency oscillators are used to respond to events or to perform heavy calculations by the CPU.
installed on the Printed Circuit Board (PCB) surface or other substrate surface, through reflow welding or immersion welding and other methods to be welded and assembled circuit installation technology.
As we all know, circuit protection is mainly to protect the components of electronic circuits from damage under the circumstances of overvoltage, overcurrent, surge, electromagnetic interference, and so on, and the selection of appropriate circuit protect
It is characterized by surface mounting of components and reflow welding technology. It has become a new generation of assembly technology for electronic products manufacturing.
As the temperature increases, the holding current and trigger current will decrease, so it is important to know the temperature of the environment in which PPTC is applied.
This circuit directly led to the development of ADC and is now almost standard in all ADCs except Delta Σ, becoming one of the classic analog circuits in history. Of course, the circuitry is not easy to understand at first glance.
In addition, in many cases, due to the reaction and dissolution, in the printed circuit industry, residual film and copper may also form accumulation in the corrosion fluid and blocked in the nozzle of the corrosion machine and acid pump, have to stop pro
