Symbols in parentheses are for type number composition.

*Resistance figures are obtained by measuring the leads at point 12.7±3.2mm away from the base for type HC

and HD, but, in case of resistance below 10 ohm, the value at 1.6±0.6mm away from the base for all types.

**Temperature characteristic Z is applicable for temperature range between 0°C and 60°C.

Resistance value, in ohm, is expressed by a series of six characters, five of

which represent significant digits. The sixth R or K is a dual-purpose letter that

designates both the value range (R for ohmic; K for kilo-ohm) and the location

of decimal point.

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.
