Detailed explanation-1: -A 6 band resistor is essentially a 5 band resistor with an extra ring that denotes the temperature coefficient or sometimes, the failure rate. The most common color for the sixth band is brown (100 ppm/K), which means that for every 10℃ change in temperature, the resistance value changes by 0.1%.
Detailed explanation-2: -The 6th band for a 6 band type resistor is the temperature coefficient. This indicates how much the actual resistance value of the resistor changes when the temperature changes. Table 5 shows these values for each corresponding color.
Detailed explanation-3: -Let’s take an example of a 6-band resistor with the colors given in the above image (brown, black, orange, red, gold and brown). So according to the formula the resistance will be: 103 * 100 = 10300 Ohms with 5% tolerance and 100 ppm/K temperature coefficient value.
Detailed explanation-4: -6-Band Resistors The change in resistance is measured in ppm/°C where ppm = R/R or the change in resistance per of rated value. A high precision resistor with a value of 68 M with a tolerance of ±5% and a Temperature Coefficient of Resistance of 250 ppm/°C is depicted below.
