VHZ HermeticVishay Foil ResistorsBulk Metal® Foil TechnologyHermetically Sealed Resistors, AerospaceFEATURES•VH102Z SeriesNominal Temperature Coefficient of Resistance:± 0.2ppm/°C MIL Range (see table 2)•VHZ555 Temperature Coefficient of Resistance:± 2ppm/°C (– 55°C to + 125°C);•Selected TCR Tracking: to 0.5ppm/°C (matched sets)The \"VHZ\" series of resistors is the hermetic version ofthe molded \"Z\" series devices. Hermetic sealing eliminatesthe ingress of both oxygen, which degrades resistors overlong periods, and moisture which degrades resistors morequickly. These parts are made with glass to metal sealenclosures employing Kovar eyelets which allow the copperleads to pass through the enclosure to minimize thethermal EMF from the lead junctions. Rubber fillbetween the metal housing and resistance element acts bothas a mechanical damper and thermal transfer path.VH102Z is the hermetically-sealed counterpart of the Z201high-performance molded resistors. VHZ555 is thehermetically-sealed version of the Z555, MIL style RNC90Z.•Load-Life Stability: ± 0.0025% maximum ∆R at 0.1 watt,+ 60°C, 2,000 hours (VHZ555)Product may notbe to scaleTHROUGH HOLE•Power Rating: 0.6 Watts at + 70°C; 0.3 Watts at + 125°C•Resistance Tolerance (Initial Resistance Accuracy):± 0.005% tightest to ± 1.0% loosest•Resistance Range:VH102Z: 100R to 100KVHZ555: 4R99 to 121K TABLE 1 - MODEL SELECTIONMODELNUMBERVH102ZRESISTANCE STANDARD RESISTANCE MAXIMUM AMBIENTRANGETOLERANCE1 %WORKINGPOWER RATING3 ††(Ω)TIGHTESTLOOSESTVOLTAGE2at + 70°Cat + 125°C100R to 100K± 0.005± 1.0± 1.0± 1.0± 1.0± 1.0± 1.0AVERAGEWEIGHT(GRAMS)WLHLL DIMENSIONS INCHES0.185 Maximum0.435 Maximum0.430 Maximum**1 ± 0.125 mm4.70 Maximum11.05 Maximum10.92 Maximum25.4 ± 3.183.81 ± 0.25 2.41 Maximum3000.6 W0.3 W1.4VHZ55530.1 to 121K20 to < 30.14.99 to < 20± 0.005± 0.01± 0.05LS0.150 ± 0.0104ST0.095 Maximum**0.375H available.FIGURE 1 - STANDARD IMPRINTING AND DIMENSIONSFront ViewLVISHAYXXXXVH102ZRear ViewW100R010.01%XXXXSTDate Code0110YearWeekLSLead Material #22 AWGRound Solder Coated CopperLLResistanceValue CodeToleranceSerial No.(Optional Marking)HModelNumberSALES• AMERICAS: foilsales.usa@vishay.com • ASIA/JAPAN: foilsales.asia@vishay.com • UK/HOLLAND/SCANDINAVIA: foilsales.eunorth@vishay.com • GERMANY/CZECH REPUBLIC/AUSTRIA: foilsales.eucentral@vishay.com • FRANCE/SWITZERLAND/SOUTHERN EUROPE: foilsales.eusouth@vishay.com • ISRAEL: foilsales.israel@vishay.comDocument Number: 63063Revision 12-Dec-05

VHZ HermeticBulk Metal® Foil TechnologyVishay Foil ResistorsHermetically Sealed Resistors, AerospaceNOTES: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 for VH102Z,specify VH102ZL.5.Maximum is 1.0% A.Q.L. standard for all specificationsexcept TCR. (For TCR information see notes 6 -8.)Typical is a designers reference which represents that85% of the units supplied, over a long period of time, willbe at least the figure shown or better.6.Vishay Nominal TCR is defined as the chord slopes ofthe relative change of resistance/temperature, expressedin ppm (parts per million), called (RT) curve from 0°C to+ 25°C and + 25°C to + 60°C (“Instrument” Range); andfrom – 55°C to + 25°C and + 25°C to + 125°C (“Military”Range). These specifications and the definition ofNominal TCR apply to all resistance values includinglow-value resistors.7.Selected TCR Tracking is available for specially orderedlots of resistors. The selected TCR tracking can be 3, 2,1 and as close as 0.5ppm/°C throughout the fulltemperature range.8TCR tracking is a measure of the similarity of resistancevalue change in two or more resistors which areundergoing the same temperature changes. Trackingcould be expressed as the difference in thetemperature coefficients of the resistors, expressed inppm/°C as (∆R1/R1 – ∆R2/R2) x 10-6/∆T°C. When a numberof resistors are referenced to a nominal TCR, the spreador envelope around the nominal would be thedifference. If the spread is ± 1.5ppm/°C about a nominal,the tracking, as defined above, will be 3ppm/°C.9.Load life ∆R Maximum can be reduced through in-house procedures.10.Inductance (L) due mainly to the leads.11.The resolution limit of existing test equipment (withinthe measurement capability of the equipment, or“essentially zero.”)12.µV/°C relates to EMF due to lead temperature differenceand µV/watt due to power applied to the resistor.THROUGH HOLEFIGURE 2 - POWER DERATING CURVE–55°C+200+70°C Double Rated PowerPercent of Rated Power @ +125°C+175+150+125Rated Power+100+75+50+250 –75 –50 –25 0 +25 +50 +75 +100 +125 +150 +175 +200Ambient Temperature (°C)SALES• AMERICAS: foilsales.usa@vishay.com • ASIA/JAPAN: foilsales.asia@vishay.com • UK/HOLLAND/SCANDINAVIA: foilsales.eunorth@vishay.com • GERMANY/CZECH REPUBLIC/AUSTRIA: foilsales.eucentral@vishay.com • FRANCE/SWITZERLAND/SOUTHERN EUROPE: foilsales.eusouth@vishay.com • ISRAEL: foilsales.israel@vishay.comDocument Number: 63063Revision 12-Dec-05
