Symbols in parentheses are for type number composition.
*Resistance figures for type PB are the values obtained by measuring the leads at
point 12.7±3.2mm away from the root, but in case of resistance below 10 ohm, the
values at 5.08±0.6mm away.
**For heat sinking, an aluminum chassis in 152.4 (L) x 101.6 (W) x 50.8 (H) x 1.0mm (T)
shall be used.

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.
