Precision resistor products can withstand short-duration pulses that exceed the device’s rated power or voltage. Pulses that are below the conditions of a short-term overload test, at 2.5 times the operating voltage, and do not exceed twice the rated voltage within 5 seconds can be easily handled by the device. Pulses that exceed the short-term overload test conditions must be evaluated one by one. In many cases, there are numerous devices that can be used for precision work, and this is particularly important in some high-end, highly precise products. The rated power of precision resistor products is specified by the standards, and precision resistors are designed with low temperature drift. Setting the power rating of precision resistors is very important for many development applications, to ensure reliable full-load operation of the equipment at an ambient temperature of 70°C. Both military and standard-grade precision resistors have their rated power decrease linearly from 70°C to zero power at 150°C, in order to limit the film temperature to 150°C. The power handling capacity of precision resistors is a feature of resistor products used in heat dissipation devices. Maintaining the film temperature at 150°C or below is an important factor for the reliable operation of these resistive products. The power handling capacity is determined by the capabilities of the chip and the mounting method used to eliminate the heat generated by resistance. The power handling capacity lists the thermal resistance values, so that our customers can determine how much power can be dissipated in their applications.
