I'm doing a soldering project for school and I need some info on certain components and how to find their polarities and such.
The parts we're using for the project are:

1uf Capacitor
.01 DIsc Capacitor (103)
555 Timer IC
10K ohm Trimmer
SP2655 Power Transistor
33K Resistor
1K Resistor
75K Resistor

Basically I need to know which of these parts have polarities and how to figure out which way they'd go on the circuit board.

Thanks
