. Under the action of alternating electric field, capacitor losses are not only related to leakage loss, it is also related to the periodic polarization establishment process.
Film CapacitorAt present, a large number of plastic film capacitors are made of polystyrene, polyethylene, polypropylene, PTFE, polyester (polyester), polycarbonate, composite film, etc.1. cl21/cbb21 Metallic Film Capacitor (CL21-B/CBB21-B metallic film box type), the use of metallic polyester/polypropylene film as the

How to understand the termination voltage requirements are relatively high? For example, some high-end cameras, microphones, car remote control, typical of some of Canon's camera and car rem
simple experiment demonstrates the presence of bone conduction, which also shows that gas conduction is more sensitive than bone conduction in normal cases. It can be considered that bone conduction has little effect on normal hearing. However, clinically, we often determine the locations and causes of auditory abnormalities by examining the patient's gas and bone conduction damage.

Principle and Application of Photoelectric Coupler
I. Principle and composition of Photoelectric Coupler
1. Principle. Photoelectric Coupler, usually referred to as photocoupler. The basic principle is to transmit electrical signals using light as a media. In some special application scenarios, the input/output end is required to achieve
The complete set of electrical appliances are mostly non-standard products that vary according to different requirements of users. The design workload is heavy, traditional manual design is prone to errors, and the product return rate is high. Therefore, how to shorten the product production cycle and improve the design quality becomes a key issue in the production of complete sets of electrical appliances.

1. RS-232-C
RS-232-C is the Electronic Industry Association (EIA)A standard for serial physical interfaces. RS is the abbreviation of the English "Recommendation Standard". 232 indicates the ID number, and C indicates the number of modifications. The RS-232-C bus standard has 25 signal lines, including a main channel and a secondary channel.
In most cases, the main channel is used. For general duplex communication, only a few signal lines are required, such as a transmission line, a receiving li

In the optimization of the structure, the boss attaches great importance to the optimization of
The year before, I found an e-book on the Internet that introduced the development of the CAD industry, "the enginnering Design Revolution", at http://www.cadhistory.net /. I think the content is wonderful. The author David E. Weisberg has been working in the CAD industry for many years. Based on his own work experience, he has read a lot of materials before writing this book.
Last year I re-read some chapters and came up with the idea of translating them to attract more readers. With the autho
