Descriere

STANDARD RESISTORS

On request various values and precision described below and boxes containing several values at your choice

Included certificate of calibration of our laboratory

Fixed value standard resistances

high-accuracy used as standard in laboratory.

SAMAR certificate of calibration is supplied with each standard resistor.

The standard production includes sample resistances multiple of 10.

 

  • Resistances realized in manganine with temperature coefficient of ± 20 ppm/°C (independent from temperature between 15 and 30 °C)
  • Long term stability:  ± 50 ppm per year
  • Resistances from 0.0001? to 0.1? are 4 terminals, two potential and two current.
  • Resistances from 1? to 10M? are wrapped in an ant-inductive way and are two terminals with 2 screws for potential and current.
