with the development of science and technology, all industries are inseparable from intelligent industry, intelligent agriculture, intelligent transportation, to intelligent logistics, intelligent security and other fields. the demand for intelligence in various fields, in essence, is the increasing...
new sensitive materials are the technical basis of sensors, and material technology research and development is an important means to improve performance, reduce cost and upgrade technology. in addition to the traditional semiconductor materials, optical fiber and so on
the substrate material is usually 96% alumina ceramic. the substrate should not only have good electrical insulation, but also have excellent thermal conductivity, electrical properties and mechanical strength at high temperature
capacitors are almost indispensable energy storage components in electronic circuits. they have the characteristics of isolating dc, connecting ac and preventing low frequency. it is widely used in coupling, isolation, bypass, filtering, tuning, energy conversion and automatic control circuits.
triode, also known as bipolar junction triode, is equivalent to two back-to-back diode pn junction. in the forward biased eb junction, holes are injected into the base region from the emitter, and most of the holes can reach the boundary of the collector junction, and reach the collector area under ...
schottky diode is a kind of schottky barrier diode based on the barrier formed by the contact between metal and semiconductor. schottky diodes are low-power, ultra-high-speed semiconductor devices. the reverse recovery time can be as small as a few nanoseconds (2-10ns nanoseconds), and the forward v...
