![]() ![]() The second reason is that resistors have a voltage limit within which they can be safely operated. Having multiple cheap standard resistors that individually heat up less is better than having a single expensive resistor that must handle the power and temperature, and may require more special arrangements to keep it cool, as the multiple resistors can be distributed evenly and allow the PCB to conduct and redistribute the heat. But the resistors with tighter tolerance will be more expensive, so since a range of resistances is fine, the resistor tolerances can also be chosen to be loose enough to have multiple cheap standard resistors.įirst reason is obvious, the resistors have a power limit. But if a single resistor could be used, a range of suitable values exist, so 62k might be within specs, or if not, 59.7k then could be. As you noticed, 60k resistors are not standard and literally don't exist. ![]() They are 10k because having six of them with some tolerance is within a suitable range. There is a purpose to having multiple resistors.Īnd also note that even if there is six 10k resistors, it does not mean that they are there because exactly 60k resistance is needed. ![]()
