Hello All,
Throughout my entire electronic education, I've always found a little 'm' to represent milli, and a capital 'M' to represent Mega. Now, the attached photos are of a power resistor from Micron. Based off of the datasheet, this is most certainly a 10 Watt resistor, and, I have even double-checked the measurements given in the table. My problem is that is says, for a 10W resistor, the ohm ranges are from 1ohm to 1kohm. This would rule out that the little 'm' has any possibility of representing Mega, so it must represent milli. However, even with the 5% tolerance, a 22milli ohm resistor is still far less than 1 ohm. So, what exactly am I missing here, and why does a resistor with such a low ohm rating need an enormously large ceramic casing?
