Resistance value
expressed as a four
digit number where
the first three num-
bers are the signifi-
cant value, and the
forth number is the
number of zeros.

Example
:
For a High Voltage, 125 Meg-ohm resistor with case size of 0805,
a TCR of + 50 ppm/C, a +1% tolerance, and wrap-around solderable
terminations - the part number would be:
