MARKING

PU2512 / 5931

No marking

PU3921 - 0.1~0.7mΩ

4 digits

The "m" is used as a decimal point ; the other 3 digits are significant

and the unit is milliohm

0.1mΩ to 0.7mΩ

PU3921 - 1~5mΩ

4 digits

The "R" is used as a decimal point ; the other 3 digits are significant

1mΩ to 5mΩ

NOTE:

There will be a short period of time that both types of PU3921, with marking and without marking, exist simultaneously in the market.
