Power Derating Curve
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.

Symbols in parentheses are for type number composition.
*Resistance figures are the values obtained by measuring the leads at point 12.7±3.2mm away from the base
for Type MA and at point 5.0±1.0mm for Types MC, MB and MD, 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.
