The performance and application of raw materials for PET Self Wrap Braided Sleeve

When it comes to PET Self wrap braided sleeve, laymen may not be clear about it, but it only needs to talk about maintenance and cleaning of computer power lines, speaker monitoring video lines, lighting, central air conditioning, refrigerators, automatic You may have some knowledge about electrical products such as washing machines and their optical cables, motorcycles, and vehicles, but it is not comprehensive. Let us master the performance and application of PET Self Wrap Braided Sleeve raw materials.

The crystalline Pet Self Wrap Braided Sleeve sleeve is a p-n junction produced by a p-type semiconductor and an n-type semiconductor, and a space charge layer is generated on both sides of the page, and an electric field is built. When there is no additional operating voltage, because the p-n junction is two The spreading current caused by the difference in free electron concentration on the side is the same as the drift current caused by the construction electric field, and is in an electric balance state. When there is an external working voltage limiter in the positive direction, the mutual suppression effect of the external electric field and the construction electric field makes the free electrons The creeping current boost of the electrons results in a positive direction current.
When the external reverse working voltage is limited, the external electric field and the construction electric field are further strengthened, and the reverse saturation state current I0 which has no relationship with the reverse bias voltage value within the reverse working voltage range is generated when the additional reverse working When the voltage is high enough, the electric field strength in the space charge layer of the p-n junction reaches the critical point to form a growth process of free electrons, forming a large number of electronic oxygen vacancy pairs, and generating a large reverse penetration current. It is called the penetration condition of the PET Self Wrap Braided Sleeve.
According to the commonly used semiconductor materials, it can be divided into germanium PET Self Wrap Braided Sleeve sleeve and silicon PET Self Wrap Braided Sleeve sleeve. Tube, voltage regulator tube PET Self Wrap Braided Sleeve, power switch PET Self Wrap Braided Sleeve, etc., according to the core tube structure, can be divided into point contact type PET Self Wrap Braided Sleeve, surface contact type PET Self Wrap Braided Sleeve Type braided sleeve and horizontal PET Self Wrap Braided Sleeve, point-contact PET Self Wrap Braided Sleeve is pressed on the surface of the bright semiconductor material chip with a thin iron wire.
Through a single pulse current, one end of the contact wire and the chip are firmly calcined together to form a "PN junction". Because it is a point contact, it can only be used for high-frequency and low-current power circuits based on relatively small currents, such as the detection of tape recorders, etc. The surface-contact PET Self Wrap Braided Sleeve sleeve has a relatively large PN junction area, which allows the rectifier used to convert AC current into DC power through relatively large currents. In the power circuit, the planar PET Self Wrap Braided Sleeve The bushing is a different kind of siliconPET Self Wrap Braided Sleeve bushing. It not only supports relatively large current, but also has relatively stable and reliable performance. It is mostly used in power switches, single pulse and high-frequency circuits.
