PB X 50R000 B
*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.

Four-Terminal Resistor
Affect of PB type lead for resistance value and TCR
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.
