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.

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.
