Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads. Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function.

I just re-did all the R's and C's in the preamp section of an aged Dynaco SCA-80. It was interesting to measure the resistors to see how they had changed.
The design has mostly half-watt 5% carbon comp resistors, with a few 10% resistors. I measured them all, and in comparison to their original values, they all had gone high. It ranged from 4% to 14% high. On average, the resistors were 8.24% higher than their nominal values. I measured 34 resistors.
