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.

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 -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 Nominal TCR is defined as the chord slopes of the relative change of resistance/temperature, expressed in ppm (parts per million), called (RT) curve from 0°C to + 25°C and + 25°C to + 60°C (“Instrument” Range); and from – 55°C to + 25°C and + 25°C to + 125°C (“Military” Range). These specifications and the definition of Nominal TCR apply to all resistance values including low-value resistors. 7. Vishay Standard TCR Spread is defined as a designers reference which represents that at least 92% of the units, and 82% of the lots, supplied by Vishay will be within the stated band centered on the nominal curve. This definition of the Vishay Standard TCR Spread from Nominal applies to all resistance values. However, as the resistance value decreases below 80 ohms, the Vishay Standard TCR Spread from Nominal specification starts to increase. (See Figure 3 in data sheet “7 Technical Reasons to specify BMF Resistive Components.”) 8. 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 ± 2.5ppm/°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 ohms, 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.”) 9. Selected TCR Tracking is available for specially ordered lots of resistors. The selected TCR tracking can be 3, 2, 1 and as close as 0.5ppm/°C throughout the full temperature range. 10. 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 (∆R1/R1 – ∆R2/R2) x 10-6/∆T°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 ± 1.5ppm/°C about a nominal, the tracking, as defined above, will be 3ppm/°C. 11 Inductance (L) due mainly to the leads. 12. The resolution limit of existing test equipment (within the measurement capability of the equipment, or “essentially zero.”) 13. µV/°C relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor. 14. Load life ∆R Maximum can be reduced through burn-in procedure.
