SMD transistor are one of the commonly used electronic component in the circuit board of all electronic products. There are also SMD diode, SMD transistor, MOS tube, etc. The simple ones are only divided into NPN and PNP, but in fact , If it is 2N3055 of NPN, then it may be TO-3 of iron shell, if it is 2N3054 of NPN, it may be TO-66 or TO-5 of iron shell, and CS9013 for learning has TO -92A, TO-92B, and TO-5, TO-46, TO-52, etc., are ever-changing.

There is also a patch resistor. In the DEVICE library, it simply calls them RES1 and RES2. It doesn’t matter whether it is 100Ω or 470KΩ. For the circuit board, it is not related to the ohms at all. The 1/4W and even 1/2W resistor we replace based on the power of the resistor can be packaged with AXIAL0.3 component, and if the power is a little larger, AXIAL0.4, AXIAL0.5, etc. can be used.
