VCS1610 (Kelvin Connection) Vishay Foil Resistors High Precision Foil Surface Mount Current Sensing Chip Resistors with TCR of ± 2 ppm/°C, Load Life Stability of ± 0.02 %, ESD Immunity up to 25 kV and Fast Thermal Stabilization FEATURES • Temperature coefficient of resistance (TCR): ± 2.0 ppm/°C typical (- 55 °C to + 125 °C, Pb-free Available + 25 °C ref.) (see table 1) RoHS* • Tolerance: to ± 0.5 % COMPLIANT • Load life stability: ± 0.02 % at 70 °C, 2000 h at rated power • Power rating: 0.25 W at + 70 °C • Electrostatic discharge (ESD) above 25 000 V • Fast thermal stabilization due to proprietary processing technique • Short time overload ≤ 0.005 % • Ohmic values: 0.2 Ω to 0.5 Ω (for higher or lower values please contact us) • Non inductive, non capacitive design • Thermal EMF: 0.05 µV/°C typical • Current noise: < - 42 dB • Rise time: 1 ns without ringing • Voltage coefficient: < 0.1 ppm/V • Non inductive: < 0.08 µH • Weight: 0.027 mg Any value at any tolerance available within resistance range INTRODUCTION Model VCS1610 is a surface mount resistor designed with 4 pads for Kelvin connection. Utilizing Vishay Bulk Metal® Foil as the resistance element, it provides performance capabilities far greater than other resistor technologies can supply in a product of comparable size. Low TCR removes errors due to temperature gradients. The VCS1610 has improved load life stability of ± 0.02 % at + 70 °C for 2000 h at rated power. Other technologies of current sensing resistors offer a load life stability of ≥ 0.5 % through a 1000 h workload. This small device dissipates heat almost entirely through the pads so surface mount users are encouraged to be generous with the board’s pads and traces. Gold terminations are available on special order. Our application engineering department is available to advise and to make recommendations. For non standard technical requirements and special applications, please contact us. TERMINATIONS • Two lead (Pb)-free options are available: Gold plated or tin plated • Tin/lead plated FIGURE 1 - POWER DERATING CURVE Percent of Rated Power - 55 °C 100 75 50 25 0 - 75 APPLICATIONS • Automatic test equipment (ATE) Electrical Schematic I1 R I2 E2 E1 + 70 °C - 50 - 25 0 + 25 + 50 + 75 + 100 + 125 + 150 + 175 • • • • • • • Ambient Temperature (°C) Airborne (in heads-up display systems) High precision instrumentation Electron beam recording equipment Electron microscopes Current sensing applications Force balance electronic scales Military • Medical • Down-hole (high temperature) TABLE 1 - TOLERANCE AND TCR VS.
