NOTES:
1. Maximum is 1.0% A.Q.L. standard for all specifications except
TCR. Typical is a designers reference which represents that
85% of the units supplied, over a long period of time, will be at
least the figure shown or better.
2. Whichever is lower.

4. Inductance (L) due mainly to the leads.
5. The resolution limit of existing test equipment (within the
measurement capability of the equipment, “essentially zero”).
6.
µV/°C relates to EMF due to lead temperature difference.

HOW TO ORDER VPR220 AND VPR221 PARTS:
Specify Vishay VPR220 or VPR221 resistors as follows:
Example:
VPR221
5R0000
1.0%
Model No.
Resistance Value
Tolerance
Specify Vishay VPR220S or VPR221S for surface mount
resistors as follows:
Example:
VPR221S
5R0000
1.0%
Model No.
Resistance Value
Tolerance
Resistance value, in ohms, is expressed by a series of 6 characters, 5 of which
represent significant digits while the 6th is a dual purpose letter that designates
both the multiplier and the location of the comma or decimal.
