INTRODUCTION
The “VH” series of resistors is the hermetic version of
several molded “S” series devices. Hermetic sealing
eliminates the ingress of both oxygen, which degrades
resistors over long periods, and moisture which degrades
resistors more quickly. These parts are made with glass
to metal seal enclosures employing Kovar eyelets which
allow the copper leads to pass through the enclosure to
minimize the thermal EMF from the lead junctions. Rubber
fill between the metal housing and resistance element
acts both as a mechanical damper and thermal transfer
path.
VHS102 and VH102K are the hermetically-sealed
counterpart of the S102C and S102K high-performance
molded resistors. VHS555 is the hermetically-sealed
version of the S555, MIL style RNC90Y.

Note
To acquire a precision resistance value, the Bulk Metal Foil
chip is trimmed by selectively removing built-in “shorting bars.”
To increase the resistance in known increments, marked
areas are cut, producing progressively smaller increases in
resistance. This method reduces the effect of “hot spots” and
improves the long-term stability of VFR resistors.

Notes:
(1)
Maximum is 1.0 % A.Q.L. standard for all specifications except TCR. (For TCR information see notes
(4)
to
(7)
.) 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)
Resistance figures are obtained by measuring the leads at point 0.5" (12.7 mm) ±0.13" (3.2 mm) away from the root.
(3)
Selected TCR tracking is available for specially ordered lots of resistors.
(4)
Vishay Foil Resistors (VFR) maximum TCR spread is defined as the 3 σ (sigma) limit of a normal Gaussian distribution (99.73%
of a production lot) which is within a band, centered on the nominal curve. This VFR maximum TCR spread is no greater than
±2.5 ppm/°C from nominal throughout the full temperature range. This definition of the VFR maximum TCR spread from nominal
applies to all resistance values. However, as the resistance value decreases below 80 Ω, the VFR maximum TCR spread from
nominal specification starts to increase.
(5)
TCR tracking is a measure of the similarity of resistance value change in two or more resistors which are undergoing the same
temperature changes. Tracking could be expressed as the difference in the temperature coefficients of the resistors, expressed in
ppm/°C as (ΔR
1
/R
1
to ΔR
2
/R
2
) x 10
-6
/ΔT°C. When a number of resistors are referenced to a nominal TCR, the spread or envelope
around the nominal would be the difference. If the spread is ±1.5 ppm/°C about a nominal, the tracking, as defined above, will be
3 ppm/°C.
(6)
Load life ΔR maximum can be reduced through in-house oriented processes.
(7)
Inductance (L) due mainly to the leads.
(8)
The resolution limit of existing test equipment (within the measurement capability of the equipment, or “essentially zero”).
(9)
μV/°C relates to EMF due to lead temperature difference and μV/W due to power applied to the resistor.
* Precaution in Usage: When soldering to mount hermetically sealed resistors on a board, keep the resistor over 0.39" (10 mm)
away from board surface by the use of an insulating tube.
