Is there ant resistors with 1% tolerance?
Yes. 1% resistors have three bands to read digits to the left of the multiplier. They have a different temperature coefficient in order to provide the 1% tolerance. They are more expensive than 20%, 10% and 5% tolerance resistors. • How about the power rating color band? There is no band to indicate the power rating of a resistor. A resistor’s weight and size indicate its power rating. Resistors with less than two watts power rating weigh a few 10s of grams, but high-power rating resistors are larger and heavier. power-dissipation ratings of resisters are usually 1/4 watt or 1/2 watt. Some carbon resistors have power-dissipation rating of more than 1/2 watt or less than 1/4 watt. When a large amount of current must be handled, resulting in a power-dissipation of several watts, wirewound resistors are used. • Why resistors are not available in equally spaced values? Resistors commonly have values such as 2.2kW, 3.3kW, or 4.7kW and are not available in equally spaced values. This is beca
