VFCD1505 (Z-Foil) Vishay Foil Resistors High Precision Bulk Metal Foil Surface Mount Voltage Divider, TCR Tracking of < 0.5 ppm/C, Tolerance Match of 0.01 % and Stability of 0.005 % (50 ppm) FEATURES Temperature coefficient of resistance (TCR): absolute: (table 1) 0.05 ppm/C (typical 0 C to + 60 C) 0.2 ppm/C (typical - 55 C to + 125 C, + 25 C ref.) Bottom View Tracking: (table 1) INTRODUCTION 0.1 ppm/C typical Bulk Metal Z-Foil (BMZF) technology out-performs all other Resistance range: 1K to 10K resistor technologies available today for applications that require ultra high precision and ultra high stability. Foil resistors are not restricted to standard values/ ratios, specific as required values/ratios may be supplied at no The new Z-Foil technology provides a significant reduction extra cost or delivery (e.g 2K234/5K456) of the resistive elements sensitivity to changes of Power coefficient tracking: R due to self heating temperature due to ambient temperature variations (TCR) 5 ppm at rated power and to self heating when power is applied (power Short time overload: 0.005 % coefficient). Tolerance: absolute and resistance ratio: to 0.01 % Model VFCD1505 offers low TCR (both absolute and Load life stability (0.1 W at 70 C, 2000 h) tracking), excellent load life stability, tight tolerance, Absolute: 0.01 % excellent ratio stability, low thermal EMF and low current Ratio: 0.005 % noise, all in one package. 0.05 ppm/C absolute TCR removes errors due to temperature gradients. Electrostatic discharge (ESD) up to 25 000 V Power rating at 70 C: entire package: 0.1 W, divided The VFCD1505 surface mount divider provides tight between the two resistors proportionally to their value tolerance matching and TCR tracking between 2 resistors Non-inductive, non-capacitive design simultaneously etched on one piece of foil on a common substrate. The electrical specifications of this integrated Thermal EMF: 0.05 V/C typical construction offers improved performances and better real Current noise: < - 40 dB estate utilization over discrete resistors and matched pairs. Rise time: 1 ns effectively no ringing Our application engineering department is available to Non inductive: < 0.08 H advise and make recommendations for non-standard Voltage coefficient: < 0.1 ppm/V technical requirements and special applications, please Non hot spot design contact us.
