• UPR Series are assembled by Token EE/RE 1/10 series
    to form a stable, high precision, and low temperature coefficient network resistors.
  • UPR Series are relatively consistent with Tolerance of Nominal Resistance and Temperature Coefficient and are good for applications like Precision Instruments, Simulation Equipments, etc...
  • The electric characteristics of UPR and UPSC are the same,
    excepting body size.
