A Brief Introduction to the Structure and Types of Neoprene Velcro Cable Sleeves

Neoprene Velcro Cable Sleeve, semiconductor material is basically one of the electronic devices, with the function of increasing the amount of current, the main part of the electronic circuit. The braided network tube is made of two PN junctions with close distances on a semiconductor material silicon wafer. The two PN junctions divide the positive semiconductor material into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. , There are two types of arrangement, PNP and NPN. The corresponding electric levels are drawn from the three regions, each of which is the base b emitter e and the collector junction c. The PN junction between the emitter region and the base region is called the emitter junction. The electrical base area is very thin, while the emission area is thicker and the impurity.

concentration is large. The PNP type braided network tube launch area "sends" cavitation, and its movement angle is consistent with the direction of the current, so the arrow symbol of the emitter is inward; the NPN type braided network tube emits The region "sends" a free charge whose angle of motion is opposite to the direction of the current, so the emitter arrow symbol points outward. The emitter arrow symbol points outward. The emitter arrow points to the on-off orientation of the PN junction under forward voltage. There are two types of silicone neoprene velcro cable sleeves and germanium neoprene velcro cable sleeves, PNP type and NPN type.

The package types of common braided network pipes include metal package and plastic package. The arrangement of the pins has certain regularity. On the right is ebc. For small output power plastic braided network management pipes, according to the picture, make the house face itself, and place the three pins downwards. From left to right, it is the current stage of ebc.
There are many kinds of neoprene Velcro cable sleeves in our country, and the arrangement of the pins is different. For the braided network pipe with uncertain pin arrangement in use, it is necessary to carry out measurement to determine the correct position of each pin. , or search the operation manual of the transistor to establish the performance of the braided network management and the corresponding main parameters and materials.
The neoprene Velcro Cable Sleeve has the function of increasing the AC current. The neoprene Velcro cable sleeve has the function of increasing the current. The essence is that the braided network tube can control the collector junction with a slight change in the base AC. The current is relatively large. amount of change.
