Note on
Power Handling
These components can safely be used at all power levels listed for their respective size. The reliability levels obtained (see table below) will be
relative to the power applied. As with most electronic devices, the higher the heat environment that the components are subjected to, the
greater the performance drift, and ultimately the shorter the expected component life. As you apply more power to the components, they
generate more heat. Therefore for a CR0805* component for example, if you were to apply 1/4 watt to the resistors it will generate more heat
than if you were to apply 1/10 watt. Referring to the reliability tables below and specifically the Load Life test, if you were to apply 1/4 watt
(high power) to a CR0805E1002B product (10KΩ), you can expect that after 1,000 hours of testing at those conditions, the change in
resistance would be ±0.5% or less. Similarly, if you were to apply 1/10 watt (low power) and the same remaining conditions to that same
component, after 1,000 hours of testing, the change in resistance would be ±0.1% or less.
