Resistors handle high energy pulses
20 February 2013
Passive Components
The SM8035 from Stackpole is a 4 Watt moulded SMD wirewound resistor with a robust wirewound element able to withstand very high surge energy. In a 1 Ω value, for example, the part has 43,3 Joules energy handling capacity. The other SM sizes similarly have impressive pulse handling for their size. Pulse handling also typically increases for lower resistance values due to the necessity to use larger diameter wire.
The SM series in general is a good choice for a wide range of power supplies and electric motor controls, as well as robotics, medical devices, test equipment, network equipment and industrial automation. It is available in tape and reel packaging.
