NOTE:  Components that are supplied on a "carrier" paper should have their leads cut from the 
carrier near the edge of the paper.  Don't try to pull the component away from the carrier 
otherwise you could damage it.

NOTE: Some components have pre-bent leads and they'll need to be reformed to allow 
the part to fully seat on the surface of the circuit board.

NOTE:  Polarized capacitor locations include a "+" (plus sign) silkscreened where the positive 
lead orients.
