Upper end of resistance range varies with model selected (i.e. VHP202; the range is to 150 k
Not to exceed power rating of resistor
Ω; VHA518-10, the range is to 1M67 Ω) per table 2
Insulating sleeve - a special case insulating plastic sleeve is available on VHA models. See table 4 for instructions on how to specify
0.200 (5.08 mm) lead spacing available - specify VH202J

Inductance (L) due mainly to the leads
The resolution limit of existing test equipment (within measurement capability of the equipment, or “essentially zero”)
µV/°C relates to EMF due to lead temperature difference and µV/W due to power applied to the resistor
Load life ΔR maximum. Can be reduced through in-house oriented processes
POST MANUFACTURING OPERATIONS OR PMO FOR IMPROVED END OF LIFE
Many analog applications can include requirements for
performance under conditions of stress beyond the normal
and over extended periods of time. This calls for more than
just selecting a standard device and applying it to a circuit.
The standard device may turn out to be all that is needed but
an analysis of the projected service conditions should be
made and it may well dictate a routine of stabilization known
as post manufacturing operations or PMO. The PMO
operations that will be discussed are only applicable to Bulk
Metal Foil resistors. They stabilize Bulk Metal Foil resistors
while they are harmful to other types. Short time overload,
accelerated load life, and temperature cycling are the three
PMO exercises that do the most to remove the anomalies
down the road. Vishay Bulk Metal Foil resistors are
inherently stable as manufactured. These PMO exercises
are only of value on Bulk Metal Foil resistors and they
improve the performance by amounts that are small but
significant when compared to the very tight tolerances. Users
are encouraged to contact Vishay Foil applications
engineering for assistance in choosing the PMO operations
that are right for their application.
