Specification Brand : SEIWEI BulletPoint1 : ❤These are standard To-92 NPN 2N2222 transistors for general purposes. The pin layout is that of any NPN transistor, with the middle being the base, one of the legs being the collector and the other emitter BulletPoint2 : ❤Good transistor for your "Bench Stock".2N2222 transistors are one of the most commonly used types.If you want to be able to prototype circuits, having a supply of these little guys is a necessity BulletPoint3 : ❤This is a good general-purpose transformer for switching.Handy to have in the parts bins BulletPoint4 : ❤Excelent transistors. Very good to prototyping using boards like Arduino,Raspberry Pi or any other microcontroler BulletPoint5 : ❤The 2N2222 is extremely common in DIY projects. If you need a small signal NPN transistor, this one is a safe bet ExternallyAssignedProductIdentifier1 : 0713806666652 ExternallyAssignedProductIdentifier2 : 713806666652 ItemName : 100PCS 2N2222 TO-92 PNP Transistor, TO-92 Power General Transistor Kit ItemPackageDimensions_Height : 6 centimeters ItemPackageDimensions_Length : 16 centimeters ItemPackageDimensions_Width : 15 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : bjt-transistors Manufacturer : SEIWEI Material : lead Material1 : Metal Material2 : Plastic Material3 : Aluminum Material4 : Aluminum Material5 : Aluminum Material6 : Aluminum Material7 : Aluminum Material8 : Aluminum Material9 : Aluminum ModelNumber : Fydunre8wtf3ngo NumberOfBoxes : 1 NumberOfItems : 20 NumberOfPieces : 1 PartNumber : rewr ProductDescription : Description Feature:
