Theyre also known as surface mount resistors. A wirewound resistor is usually a very good choice.

Resistor Power Rating And The Power Of Resistors

Resistors are rated by power 14 watt 12 watt.

Resistors max voltage. 1 for shorter pulse durations a higher peak voltage may be. The pulse peak voltage ui the resistors datasheet specifies the nominal power dissipation at an ambient temperature of 70 0c as p70. 2 when you just have high voltage drops large resistor values.

The power rating of resistors can vary a lot from less than one tenth of a watt to many hundreds of watts depending upon its size construction and ambient operating temperature. Thick film resistors can be used with any electrical device with a battery or ac connection. The voltage dropped across large value resistors can be exceeded before the power dissipation reaches its limiting value.

Most resistors have their maximum resistive power rating given for an ambient temperature of 70 oc or below. Often design standards recommend running a resistor at a maximum of 60 or even les of the maximum rated voltage to ensure reliability is maintained. Perhaps in extremely high voltages there is a maximum voltage rating but i have been an electronic engineer for 40 years and have never run across that parameter.

Theyre also known as through hole resistors. The power rating is completely independent of the voltage rating. These resistor specifications are some of the more commonly seen resistor specifications and parameters.

The voltage rating is for the resistor series typically and specifies the maximum peak voltage you can apply without danger of damaging the resistor due to corona breakdown arcing etc. The metering circuit that was intended ot measure the amplifiers anode dc voltage used three 47 megaohm resistors in series with a lower value resistor in the series string to ground the meter was placed across this low value resistor. Use carbon film resistors in high voltage machines such as x rays and radar.

Other exist and manufacturer datasheets should be consulted before settling on a given type. For pulses whose duration ti is not small compared to the components time constant for warming up the pulse voltage must not exceed. Resistors are not only specified with a maximum power dissipation but also for a maximum voltage drop.

Exceeding this voltage causes the resistor to degrade slowly reducing in resistance. 3 4 1206 resistors in series for 230vac and 4 5 for 400vac are good numbers. Use a series network with resistors for ex.
