RHOPOINT COMPONENTS LTD Spec Sheet R101-1/2 July 97 Technical Data Resistance Range Tolerances Temperature coefficient ( TCR ) Applicable temperature range Load capacity Thermal resistance to ambiente Dielectric withstanding voltage Inductance ( R = 10 mOhm ) Stability ( nominal load at 70 °C ) Remarks: 1 mOhm - 100 Ohm 0.1 %, 0.5 %, 1 % < 10 ppm/K ( 20 °C to 60 °C ) -55 °C to +125 °C 1W Rth < 30 K/W 1000 V AC < 10 nH deviation < 0.05 % after 2,000 h - Standard resistance values according to E12 with the additionel values of 2 and 5 - Minimum quantity of other values on request - Tolerance 0.1% for values from 5 mOhm Resistor type A-N with its separated current and voltage connections configured as a four-terminal resistor (i.e., Kelvin connection) is ideally suited for precise current measurement, current limitation or regulation in power units, current sources, and electronic loads. It is also applied for current measurements in pulse width modulated (PWM) control circuits for inductive users such as servo and stepper motors and solenoid driver circuits. Design in foil technique and application of precision resistance alloy MANGANIN warrants for a long term stability. By optimization of the shape, a high load capacity was obtained while maintaining accuracy and small inductance.
