Stackpole’s HDM Series is an axial leaded carbon film based technology. Through proprietary materials and processing, the company asserts it has achieved excellent moisture withstanding for the HDM without significant increase in manufacturing costs. This series can survive 100 hours in a pressure cooker at 120°C, over 98 percent relative humidity and two atmosphere’s pressure while standard carbon film and metal film resistors would fail, according to the company. Stackpole’s HDM Series is appropriate for industrial equipment and controls, industrial power systems, HVAC, remote communications infrastructure, outdoor lighting and security, electronic irrigation controls, UPS and emergency power systems, and instrumentation. Pricing varies with size and tolerance and ranges from $0.012 to $0.025.
