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

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 ® Z-Foil. 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). 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. Our application engineering department is available to advise and make recommendations. By Vishay Intertechnology
