# Common Resistor and Capacitor Values

#1

Standards are set in place that help determine common resistor and capacitor values. The values are calculated using some math magic (see: Renard Series & E series of Preferred Numbers). This process helps simplify inventory and purchasing needs.

This explains why you find more resistor options in a common value such as 4.99k ohms rather than values like 5k ohms. Because of this, common values are typically less expensive and more readily available (aka “stocking”) than non-common values.

Keep in mind too that tolerances play a part in common values. In the example given above for 4.99k ohms, let’s take a look at a 1% tolerance. This means that the actual resistance value can be as low as 4940 ohms or as high as 5039.9 ohms and still be deemed acceptable. Offering a 5k resistor would be redundant for a product offering.

The tightest tolerance I have ever seen on a resistor is 0.001%, so it feels safe to say that you will never encounter a perfect resistor with no tolerance at all. And since we’re discussing common instances in this post, it may be warranted to note that most commercial tolerances fall in the 1% to 10% range.

Here’s an example of resistor kit # 541-1420-ND based off of E96 values:
