This guide should allow you to quickly find components. There are 3 parts :
This document should print successfully, but larger versions of the component overlay can be obtained by clicking on the smaller image and either printing directly or saving the GIF image and scaling it using some image software (newer browsers will do this automatically).
Resistors are shown in ohms, and a 2k2 designation means 2.2 k ohm (ie. 2,200 ohms). Resistors in brown have a tolerance of 5%, and resistors in light blue have a tolerance of 1% and the two types should not be mixed. Capacitors are shown in uF (micro Farad) and nF (nano Farad). Dark blue capacitors are block monolithic (decoupling). The yellow capacitors are polyester (higher tolerance). The purple capacitors are electrolytic, so note their orientation shown with a (+) and a black bar for (-)ve (although the actual capacitor will probably have a white line to denote (-)ve).
Note 1 : The parts kit contains everything for a wideband unit, and the two connectors to make up the cable to the sensor, but does NOT contain the wire to make the cable to the sensor.
