RHOPOINT COMPONENTS LTD Spec Sheet R101-1/2 July 97 Technical Data Resistance Range 1 mOhm - 100 Ohm Tolerances 0.1 %, 0.5 %, 1 % Temperature coefficient ( TCR ) < 10 ppm/K ( 20 °C to 60 °C ) Applicable temperature range -55 °C to +125 °C Load capacity 1W Thermal resistance to ambiente Rth < 30 K/W Dielectric withstanding voltage 1000 V AC Inductance ( R = 10 mOhm ) < 10 nH Stability ( nominal load at 70 °C ) deviation < 0.05 % after 2,000 h Remarks: - 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. ∆R/R20 [%] P / P Nenn 1 0.2 0.75 -40 -20 20 40 60 80 100 120 T [oC] 0.5 -0.2 0.25 -0.4 0 20 40 power derating curve dimensions ( mm ) 60 80 100 120 TU / [oC] Temperature dependence of the electrical resistance of ISA-PLAN Resistors Spec Sheet R101-2/2 July 97 Available terminals F1 Standard / F2 on request K1- R >10 mOhm K2 - R from 1 - 10 mOhm ordering example: A-N - R010 - F1 - K2 - 0,1 type resistance value terminal tolerance A-N 10 mOhm F1-K2 0,1 % ( Technical modifications reserved ) RHOPOINT COMPONENTS LTD Holland Road, Hurst Green, Oxted, Surrey, RH8 9AX, ENGLAND Tel: +44/01883 717988 Fax: +44/01883 712938 Email: [email protected] Website: www.rhopoint.co.uk
