Capacitor values

[old_tv_nut]

Another thing to note about resistors - most modern resistors are made to the tolerance stated. The carbon composition resistors, however, could not really be made to 5% or tighter tolerance, and therefore 5% resistors were picked out by testing at the end of the process line. This means that the 10% tolerance resistors of the same nominal value would be the leftovers, and would have a bimodal distribution, at least plus or minus 5% off from the nominal value.
