Conductors

Request a sample

DuPont has a broad offering of conductors for resistor terminations, including polymeric conductors for lower temperature applications and substrates. Additional benefits include low noise characteristics (rated up to five times better than those of conventional systems), improved post-laser trim stability (improved by a factor of three), and outstanding durability at high temperatures.
