Tolerance is the percentage of error between the actual measured resistive value and the stated value. This is due to the manufacturing process and it is expressed as a percentage of its preferred value Calculating In a three-band resistor, the first two bands represent the first two significant digits followed by one band for the multiplier. Since no tolerance band is available, the tolerance will always be ±20%.

So the total value of the resistance given by the colors is 10 (from digits) x 10 5 (from multiplier) Ω = 100,000Ω = 100k Ω. For example, if you want to calculate the value of a resistor that will allow a current of 1 ampere to flow through it when a voltage of 100 volts is applied across it, you would use the following formula: It was a hell of a job to find the right values to reach a wide range of values, fairly equaly spread.When the resistor body surface is large enough, as in large wattage resistors, the resistance value, tolerance, and wattage are usually printed on the body of the resistor. Surface mounted resistors (SMD) use another coding system that uses alphanumeric codes printed on its surface instead of color codes.

Band Three – Multiplier: Takes the digits and multiplies them by a value given by this band. The actual multiplier is 10 n, where n is a value that corresponds to the color of the band. In this case, the third band is yellow which corresponds to the number 5. Therefore the multiplier is 10 5 = 10,0000. In a six-band resistor, the first five bands have the same representation as a five-band resistor followed by one extra sixth band that represents the temperature coefficient of resistance (TCR).

Schematic symbol

Resistors will come in one of two termination-types: through-hole or surface-mount. These types of resistors are usually abbreviated as either PTH (plated through-hole) or SMD/SMT (surface-mount technology or device). In my new concept I integrated the pulldown resistor as beeing part of the left side of the resistors. Six band resistors are exactly like five band resistors except they have an extra band to indicate the temperature coefficient, i.e. how much the resistance will change with temperature.
