Stackpole’s SM8035 for High-Energy Pulse Applications

The SM8035 from Stackpole Electronics, Inc. is a 4W molded SMD wirewound resistor. The robust wirewound element is able to withstand much higher surge energy than other film surge resistors. The SM8035 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 resistor energy capacity examples: Part number SM2615__1R00 (1W/1 Ohm) is rated for 1.7 J. Part number SM4124__1R00 (2W/1 Ohm) is rated for 2.7 J. Part number SM6227__1R00 (3W/1 Ohm) is rated for 17.2J. And part number SM8035__1R00 (4W/1 Ohm) is rated for 43.3J. 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. Many common values are available from stock.
