SMR1D/SMR3D Vishay Foil Resistors High Precision Bulk Metal Foil Molded Surface Mount Resistor with TCR down to 2 ppm/C, Flexible Terminations, and Load Life Stability of 0.005 % (50 ppm) FEATURES Temperature coefficient of resistance (TCR): 2 ppmC typical (- 55 C to + 125 C, + 25 C ref.) Tolerance: to 0.01 % Flexible terminations ensure minimal stress transference from the PCB due to a difference Any value at any tolerance available within resistance range in thermal coefficient of expansions (TCE) Electrostatic discharge (ESD) above 25 000 V INTRODUCTION Load life stability: 0.005 % (70 C, 2000 h at rated power) The SMRxD is a precision molded surface mountable Resistance range: 5 to 80 k (for higher and lower resistor offering all the elements of precision including low values, please contact us) TCR, tight tolerance, long term stability, low noise, low Power rating: to 600 mW at 70 C thermal EMF, and non-measurable voltage coefficient. It Non inductive, non capacitive design utilizes the Bulk Metal Foil technology for the resistive Current noise: - 40 dB element with its inherent low and predictable TCR and long Voltage coefficient: < 0.1 ppm/V term stability. This surface mountable product affords similar Non inductive: < 0.08 H performance to the time tested S series molded through-hole Non hot spot design product. Terminal finishes available: lead (Pb)-free tin/lead alloy The flexible terminations of this product also reduce Matched sets with TCR tracking are available upon request stress transference from the PCB to the resistor. Any value available within resistance range (e.g. 1K234) Voltage division with tight tracking < 3 ppm/C can be Prototype samples available from 48 h.
