Vishay's new SMR1DZ and SMR3DZ Z-Foil resistors now available from TTI
TTI, the passive and connector specialist, has introduced the Vishay SMR1DZ and SMR3DZ
ultra high precision surface mount resistors that use Vishay's breakthrough Z-Foil technology to deliver a significant reduction of the resistive component's sensitivity to ambient temperature variations (TCR) and applied power changes (PCR). Z-Foil improves stability by an order of magnitude compared to any other resistor technology, allowing designers to guarantee a high degree of accuracy in fixed-resistor applications. Featuring flexible terminations to ensure minimal stress transference from the PCB due to a difference in thermal coefficient of expansion, the devices offer a resistance range of 5Ω to 80kΩ, a low typical TCR of ±0.05 ppm/degC from 0 to +60degC and ±0.2 ppm/degC from -55 to +125degC with many value and tolerance combinations available to designers for their specific application requirements.
Applications for the new devices include precision amplifiers; high-precision instrumentation; medical and automatic test equipment; high-end stereo equipment; electron beam scanning and recording equipment; equipment and instrumentation for military, aerospace, and down-hole environments.
