Orientation and Polarity of the Components

Polarity of the BAT41 Diode

Note the polarity of the BAT41 diode. The Band on the diode must match up with the band printed on the circuit board:

Orientation of the MPSA13 Transistor

The Transistor must also be installed into the circuit the correct way around. Note the image of the transistor printed onto the

circuit board. This must be matched with the shape of the body of the transistor.

Orientation of the resistor and capacitors

The resistors and capacitors (film) are not polarized and can be inserted into the circuit board either way

Reference Designators

The reference designator (the letter followed by a number found on the bill of materials, see picture below) identifies the

component of an electrical schematic. This Reference Designator ("refdes" for short) also appears on the silkscreened printing

on the circuit board. See below an example of the reference designator for R1, a 10k resistor, found on the bill of materials

and the printed circuit board. So for R1, we would solder a 10k resistor into this position.
