The HDM Series from Stackpole is an axial leaded carbon film technology resistor with moisture withstanding capability. Axial leaded resistors that need to withstand high humidity typically require a metal glaze technology which is considerably more expensive. The HDM Series can survive 100 hours in a pressure cooker at 120°C, over 98% relative humidity and two atmosphere’s pressure while standard carbon film and metal film resistors would fail.
Stackpole’s HDM Series is a suitable choice 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 for the HDM varies with size and tolerance and ranges from $0.012 to $0.025 each in full reel quantities.
