Product Information

All resistors have a tolerance, which means that the value is unlikely to be exactly 100k Ohms. Higher quality resistors have better tolerances. Six band resistors are basically five band resistors with an additional band at the end that indicates the temperature coefficient. This indicates the expected change in resistor value as the temperature changes in degrees Celsius. Generally these temperature coefficient values are extremely small, in the ppm range. Decoding Resistor Color Bands 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%. Four band resistors have two bands for the value, one for the multiplier, and one for the tolerance. They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines. Resistor units

The color coding for resistors is an international standard that is defined in IEC 60062. The resistor color code shown in the table below involves various colors that represent significant figures, multiplier, tolerance, reliability, and temperature coefficient. Which of these the color refers to is dependent on the position of the color band on the resistor. In a typical four-band resistor, there is a spacing between the third and the fourth band to indicate how the resistor should be read (from left to right, with the lone band after the spacing being the right-most band). In the explanation below, a four-band resistor (the one specifically shown below) will be used. Other possible resistor variations will be described after. Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit. Since the context usually makes it clear that we're talking about resistor values, it's common short-hand to drop the 'Ω' so that, for example, you can write "39K"* instead of "39KΩ". They are read exactly the same way as five band resistors, except that the (additional) last band tells us the temperature coefficient. Color

The coding is defined in the international standard IEC 60062:2016. It describes the coding standard for both resistors and capacitors. Reading Color Codes

It is very easy to read 5 or 6 band resistors if you already know how to use four band resistor color coding. 5 Band 100K Resistor Color CodePower is the rate at which energy is transformed into something else. It's calculated by multiplying the voltage difference across two points by the current running between them, and is measured in units of a watt (W). Light bulbs, for example, power electricity into light. But a resistor can only turn electrical energy running through it into heat. Heat isn't usually a nice playmate with electronics; too much heat leads to smoke, sparks, and fire! The third band is the multiplier. Multiply the value designated by the first two bands with the multiplier to find the full value of the resistor.
