WIth a robust wirewound element able to withstand a higher surge energy than other devices of its type, the SM8035 4-watt molded SMD wirewound resistor from Stackpole in a 1 ohm value, for example, has the energy handling capacity of 43.3 Joules. 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. SM Wirewound Energy Capacity Part number Power Rating (W) Resistance Value (ohms) Energy Capacity (J) SM2615__1R00 1 1 1.7 SM4124__1R00 2 1 2.7 SM6227__1R00 3 1 17.2 SM8035__1R00 4 1 43.3 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. The SM8035 is available in tape and reel packaging. Pricing varies with resistance value and tolerance and ranges from $0.44 to $0.63 each in full reel quantities.
