Jun 9 2016 – The new SM Series wirewound resistor from Stackpole is a robust surface-mount device capable of handling up to 4Wt. The SM8035 case size can handle over 50J of energy while the SM2615 size can withstand more than five times the energy of a comparable size pulse withstanding flat-chip resistor.
A single SMT device is an ideal solution for applications that demand high continuous power with low heat rise. The compliant metal terminations eliminate part and solder joint cracking problems.
In addition, the SM can operate safely in temperatures up to 275C where typical flat-chip resistors can only operate at temperatures up to c.155C.
Applications include engine controls, electric motor, fan, pump controls, power conversion, current limiting for circuit protection, test, measurement, data acquisition, precision automation systems an thermostats.
