303139, 303140 Vishay Foil Resistors Models # 303139 and 303140 - Molded Surface Mount Space and Military Grade Resistors SMRxDZ with Screen/Test Flow in Compliance with EEE-INST-002, (Tables 2A and 3A, Film/Foil, Level 1) and MIL-PRF-55182 FEATURES * Temperature coefficient of resistance (TCR): 0.2 ppmC typical (- 55 C to + 125 C, + 25 C ref.) * Tolerance: to 0.02 % * Power coefficient of resistance (PCR) "R due to self heating": 5 ppm at rated power * Flexible terminations ensure minimal stress transference from the PCB due to a difference in thermal coefficient of expansions (TCE) * Electrostatic discharge (ESD) up to 25 000 V * Load life stability: 0.005 % (70 C, 2000 h at rated power) INTRODUCTION * Resistance range: 5 to 40 k The 303139, 303140 are ultra high precision molded surface mountable resistors offering all the elements of precision; including low TCR, tight tolerance, long term stability, low noise, low thermal EMF, and non-measurable voltage coefficient. One of the important parameters influencing stability is the temperature coefficient of resistance (TCR). Although the TCR of foil resistors is considered extremely low, this characteristic has been further refined over the years. These resistors utilize ultra high precision Bulk Metal(R) Z-Foil. * Vishay Foil resistors are not restricted to standard values; specific "as requested" values can be supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K) The Z-Foil technology provides a significant reduction of the resistive element's sensitivity to ambient temperature variations (TCR) and to self heating when power is applied (power coefficient). * Non hot spot design Voltage division with tight tracking < 2 ppm/C can be achieved with 2 randomly selected units even with a large ratio between the two values. * For oriented performances please contact us TABLE 1 - TOLERANCE AND TCR VS.
