Resistance figures are obtained by measuring the leads at point HC Y 30K000 T 12.73.2 mm away from the base for type HC and HD, but, in case of resistance below 10 ohm, the value at 1.60.6 mm away from the base for all types. **Temperature characteristic Z is applicable for temperature range between 0C and 60C. POWER DERATING CURVE (%) Resistance value, in ohm, is expressed by a series of six 250 characters, five of which represent significant digits. The sixth R or K is a dual-purpose letter that designates both the value 200 range (R for ohmic K for kilo-ohm) and the location of decimal point. 150 CONFIGURATION (DIMENSIONS IN mm) 100 HC, HD Type HG Type 50 70 25 50 75 100 125 150 (C) Ambient Temperature FOUR-TERMINAL (KELVIN) CONNECTION For low ohmic resistor (less than 10 ohm), the resistance value and TCR of the copper lead increases overall resistance value. Four-terminal (Kelvin) connection is recommended per the following figure. Loading current at voltage and current terminals (V, I) causes measurement error.
