precision resistors
  • Precision Network Resistors Low TCR UPRND Series meets ROHS requirements.
  • UPRNS: Serial Dip Type; UPRND: Parellel Dip Type
  • UPRNS/UPRND Series are relatively consistent with Tolerance of Nominal Resistance and Temperature Coefficient and are good for application's Precision Divider, Bypass, etc...
  • UPRNS/UPRND Series are assembled by EE/RE 1/10 series to form a stable, high precision, and low temperature coefficient Precision Network Resistor. Characteristic of UPRNS/UPRND Series meet.

Remark
  • Absolute value means all factors (Tolerance and Temperature Coefficient) of component element units of
    Network Resistor are independent.
  • Relative value means the maximum difference factor among component element units of Network Resistor.
Examples for Construction
Moulding High Precision Low TCR
  • There are no standard nominal resistance for UPRNS/UPRND Series.
  • Customer can designate or specify the number of component elements of Network Resistor according with this specification of UPRNS/UPRND Series to meet your own needs.
  • It can be required to Token's representatives if customer's requirement beyonds the range of Token's specifications.
