Resistance figures are the values obtained by measuring the leads at point 5.080.6 mm away from the root. ** For heat sinking, an aluminum chassis in 152.4 (L) x 101.6 (W) x 50.8 (H) PD X 50R000 B x 1.0 mm (T) should be used. 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. CONFIGURATION (DIMENSIONS IN mm) T2 L Type PD L 10.6 max.
