Any value at any tolerance available within resistance range

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.

Notes:

1) Standard resistance tolerance: ± 0.005 %; ± 0.01 %; ± 0.02 %;

± 0.05 %; ± 0.1 %; ± 0.25 %; ± 0.5 %; ± 1.0 %.

2) Not to exceed power rating of resistor.

3) See Figure 2 below.

4) 0.200" (5.08 mm) lead spacing available (except VHS555) -

specify VH102J (S102C type), VH102L (S102K type).

5) Maximum is 1.0 % A.Q.L. standard for all specifications except

TCR. (For TCR information see notes 6 to 10.) 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.

6) Vishay 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

Vishay maximum TCR spread is no greater than ± 2.5 ppm/°C

from nominal throughout the full temperature range. This

definition of the Vishay maximum TCR spread from nominal

applies to all resistance values. However, as the resistance

value decreases below 80 Ω, the Vishay maximum TCR spread

from nominal specification starts to increase. (See Figure 3 in

datasheet “7 Technical Reasons to Specify Vishay Bulk Metal®

Foil Resistive Components”)

7) Selected TCR tracking is available for specially ordered lots of

resistors. The selected TCR tracking can be 3, 2, 1 and as close

as 0.5 ppm/°C throughout the full temperature range.

8) 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 (ΔR1/R1 to ΔR2/R2) 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.

9) Inductance (L) due mainly to the leads.

10) The resolution limit of existing test equipment (within the

measurement capability of the equipment, or “essentially zero”)

11) µV/°C relates to EMF due to lead temperature difference and

µV/W due to power applied to the resistor.

12) Load life ΔR maximum can be reduced through in-house

oriented processes.
