* Symbols parenthesized are for type number composition.
† Resistance figures are the values obtained by measuring at the point
2.5±1.0 mm below the shoulder of leads.
POWER DERATING CURVE
Resistance value, in ohm, is expressed by a series of six
characters, five of which represent significant digits. 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.
