Specification Brand : ezqnirk BulletPoint : Please select the model you need BulletPoint1 : The model and specifications are the same as those written in the title BulletPoint2 : Each of our packages is packaged in a reliable and secure manner. Please carefully check for any goods upon receipt. If there is any damage during transportation, please contact me. BulletPoint3 : There are multiple manufacturers for individual electronic component models, and the production dates may also vary. Therefore, the pictures we provide are for reference only. BulletPoint4 : The commonly used packaging forms for transistors include metal packaging and plastic packaging, and the arrangement of pins has a certain pattern BulletPoint5 : According to the different structures and working principles, transistors can be divided into two types: NPN type and PNP type. The collector and emitter of NPN type transistors are both N-type semiconductors, while the base is P-type semiconductors; On the contrary, The collector and emitter of PNP type transistor are both P-type semiconductors, while the base is N-type semiconductors.
