Appendix DStandard Composition Resistor ValuesThe most commonly used type of resistor is the carbon ﬁlm resistor with a ± 5 percent tolerance and either a 1/4 or 1/2 watt power rating. The standard resistance values for this type of resistor are listed in the following table (in ohms). You should purchase resistors at any of these values through the online distributors listed in Appendix E, “Supplemen-tal Resources.” Power resistors are available with fewer resistance values, which you can ﬁnd in the catalogs of various suppliers.NOTEIn the following table, “k” represents kilo-ohms, so 7.5 k translates into 7,500 ohms. Similarly, “M” stands for megohms, so a value of 3.6 M represents 3,600,000 ohms.2.2242703.0 k33 k360 k2.4273003.3 k36 k390 k2.7303303.6 k39 k430 k3333603.9 k43 k470 k3.3363904.3 k47 k510 k3.6394304.7 k51 k560 kContinuedbapp04.indd 5196/14/2012 5:10:48 PM
