Surge Resistor Guards Motor Control Circuits

Groomed for use in small-motor control circuits, the HSF series surface-mount, surge resistor exploits a cylindrical design to aid heat dissipation and produce higher surge/pulse capabilities than comparable flat chips. Power rating is 1W at 70°C with a maximum operating temperature of 150°C, and resistance values range from 10Ù to 10 kÙ with a 10% tolerance. Other features include TCRs of ±50 ppm/°C and ±100 ppm/°C. Pricing is $0.14 to $0.16 each/100,000 with lead times from six to eight weeks. IRC INC., Boone, NC. (828) 264-8861.
