Resistor standard values 01. Standard resistor values in 1952 the iec international electrotechnical commission decided to define the resistance and tolerance values into a norm to ease the mass manufacturing of resistors. Tom brannon created date. Standard resistor values 5 10 10 100 10k 10k 100k 10m 11 11 110 11k 11k 110k 11m 12 12 120 12k 12k 120k 12m 13 13 130 13k 13k 130k 13m.

Standard base resistor values are given in the following tables for the most commonly used tolerances 1 2 5 10 along with typically available resistance ranges. To determine values other than the base multiply the base value by 1 10 100 1k or 10k. Round the results to the proper number of significant figures 3 for 1 and 2 2 for 5 and 10.

113 can be 113 113 113k 113k 113k or 113meg brannon electronics inc. Standard resistor values are calculated using the simple formula given below. Standard resistance value is obtained from the above chart by multiplying by powers of 10.

01 025 and 05 use e192. A more complicated task is to pick resistors to satisfy a ratio. For this task use the resistor value calculator.

As the chart at the right shows created in excel plotting the values on a logarithmic scale results in a straight line. These values are generally available in multiples of 01 1 10 100 1 k and 1 m. Standard resistor values are calculated using the simple formula given below.

Sometimes we need a resistor value more precice than what is offered in the standard series. Use of standard values is encouraged because stocking progr ams are designed around them. The e192 series of standard resistor values also exist but their use is much smaller than those in the other ranges given above.

This is often done to set the division ratio in a voltage divider for example. Resistance tolerance 01 resistors fixed manufactured by vishay a global leader for semiconductors and passive electronic components. Standard value decade for 1 resistors author.

Their tolerance is either 05 or 025 and this results in increased costs along with the fact that there is a much higher number of resistors in the range. Successive values within a decade series are related approximately by a factor of for the e12 series for the e24 series for the e96 series and for the e192 series.
