Transistors
25 – 1 x MPF102 transistor
–
Orientation is vital -
Ensure the flat face on the component
match
es the flat
face
on the PCB silkscreen.
Be careful to individually identify all the transistors, there are many different types to
separate, make sure what you have matches the label on the transistor bag.
