The size of any type of resistor mainly depends on its power or wattage rating. When the resistor size is high, then it handles with a high wattage value. The followingresistor power rating chartwill provide information regarding the rating of various resistors & their sizes. Resistor Size When...
Resistor Derating Chart - The vertical axis represents the percentage of nominal rating for a given ambient temperature. The horizontal axis is the ambient temperature. In this case, the resistor's full power rating is available up to 70 °C. ...

resistor can dissipate without damaging or altering the properties. Based on the operating conditions and environment, the nominal power rating can decrease. For example, at high ambient temperatures, the resistor power rating is de-rated to a lower value. This is expressed in a derating chart. ...
For large power resistors, the resistor body is big enough to print the resistance value, tolerance, and wattage rating on them. But for small rating resistors say 0.25 W resistors are very small in size and it’s difficult to print its value directly onto the component surface. Hence a st...

For high power applications the power rating is important. This specifies the maximum operating power the component can handle without altering the properties or damage. The power rating is usually specified in free air at room temperature. Higher power ratings require a larger size and may even ...

The LEV limit becomes more significant with pulsed applications of lower-valued resistors where the average power dissipated may be very low, but the peak applied voltage can exceed the LEV. Pulse applications may stress the power rating of the resistor as well as the voltage; the average power...
