RALEIGH, NC (Mar. 27, 2018) – The HDM series from Stackpole is   an   axial   leaded   carbon   film   technology   resistor   with   outstanding   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  120ºC,  over  98%  relative  humidity  and  2  atmosphere’s  pressure  while standard carbon film and metal film resistors would fail.
