VHP100 Vishay Foil Resistors Ultra-High Precision Hermetically Sealed Bulk Metal® Foil Resistor with Zero TCR, no Humidity Effect and 0.005 % Tolerance within a Unique Construction, Minimizing the Effects of Stress Factors FEATURES INTRODUCTION The new VHP100 type represents a metrology breakthrough. A new construction concept combined with special treatments make this resistor the first choice in the most demanding instrumentation and laboratory applications. The ability of the new VHP100 to minimize the changes in resistance value when the resistor is subjected to load variations and thermal stresses, ensure the ultra high performances for the tight metrology specifications. The total error budget of 2 ppm drift and the high speed recovery represent an improvement of almost an order of magnitude on the earlier model. Vishay has achieved an essentially Zero Temperature Coefficient Resistor in the VHP100 type. This oil filled hermetically sealed device makes unique use of foil on ceramic in such a way that self cancelling responses to temperature are produced by combining equal and opposite effects. This product is sold only in hermetic packages because applications requiring this level of temperature stability require humidity stability as well. The value of the hermetic enclosure over the molded part is in the long term performance. The hermetic sealing prevents the ingress of moisture and oxygen, while the oil acts as a thermal conductor. TCR WINDOW DEFINITION The TCR of the VHP100 is so small that an additional definition - window, has been introduced. The window definition requires that the absolute resistance remain within the stated window over the temperature range specified. The resistance of the VHP100 resistor stays within a 60 ppm window over the entire military temperature range of - 55 °C to + 125 °C (figures 1 and 3). A window of 10 ppm is available for the laboratory instrument range (+ 15 °C to + 45 °C); see figure 4 - type VHP101. TCR TRACKING Tracking of the VHP100 resistor is also vastly superior to conventional precision resistors. Typical ± 5 ppm/°C precision resistors have a worst-case tracking of 10 ppm/°C (wirewounds, thick film, thin film) or a difference between resistors of 1000 ppm (10 ppm/°C x 100 °C) when temperature changes from + 25 °C to + 125 °C. For a 3 ppm/°C tracking (Vishay S102C) the difference will be 300 ppm (3 ppm/°C x 100 °C) for the same temperature range. The VHP100 resistors will track to 60 ppm from - 55 °C to + 125 °C, a five-fold improvement over the S102C resistor. • Essentially zero TCR • Absolute resistance change (window): VHP100 < 60 ppm (- 55 °C to + 125 °C) VHP101 < 10 ppm (+ 15 °C to + 45 °C) • Tolerance: to ± 0.005 % (50 ppm) - (available to ± 0.001 % (10 ppm)) • No humidity effect: hermetically sealed against moisture • Load life stability: ± 50 ppm typical for 2000 h, 70 °C at 0.3 W • Shelf life stability: ± 2 ppm typical after at least 6 years • Resistance range: 100 Ω to 150 kΩ (higher or lower values available on request) • Vishay Foil resistors are not restricted to standard values; specific “as required” values can be supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K) • Electrostatic discharge (ESD) up to 25 000 V • Non inductive, non capacitive design • Rise time: 1 ns effectively no ringing • Thermal stabilization < 1 s • Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB) • Thermal EMF: 0.05 µV/°C typical • Voltage coefficient: < 0.1 ppm/V • Inductance: < 0.08 µH • Non hot spot design • Hermeticity: 10-7 atmospheric cc/s max. • Terminal finish: lead (Pb)-free, tin/lead alloy • Compliant to RoHS directive 2002/95/EC • Oil filled as standard, air filled available upon request • Load-life stability can be considerably improved through in-house oriented tests POST MANUFACTURING OPERATIONS ENHANCE THE ALREADY GREATER STABILITY OF FOIL RESISTORS These PMO operations are uniquely applicable to resistors made of resistive foil and they take the already superior stability of foil devices one step further. The PMO operations described are not applicable to thick film, thin film, or wire. They constitute an exercising of the resin that bonds the foil to the substrate. The exercises that are employed are (1) temperature cycling (2) short time overload, and (3) accelerated load life. TEMPERATURE CYCLING This exercise is done initially in the chip stage of all production and will eliminate any fallout in the PMO cycling. The cycling exercises the bonding resin and relaxes the foil without reducing the bonding strength. A small reduction in resistance is tolerable during this PMO operation. * Pb containing terminations are not RoHS compliant, exemptions may apply Document Number: 63003 Revision: 23-Mar-10 For any questions, contact: foil@vishaypg.com www.foilresistors.com 1 VHP100 Vishay Foil Resistors SHORT TIME OVERLOAD ACCELERATED LOAD The standard load-life curve of a foil resistor exhibits a change in the beginning and not much change after the first 100 h. This knee in the load-life curve can be removed so that the resistor is now always on the flat part of the curve by employing the PMO exercise of accelerated loading. How much acceleration is a function of the application and should be worked out between our applications engineering department and your design team. These same operations when applied to resistors of thick film, thin film, and wire have vastly different consequences and are applicable to foil only. They are an enhancement to foil performance but can drive other devices out of tolerance or open. The failure mechanisms in these other devises are too numerous to discuss here but suffice it to say, foil is the least affected by these PMO operations and they should be considered when the level of stability required is beyond the published limits for standard product.
