Surface-mount resistors major on
stability

Ultra-high-precision surface-mount resistors use Z-Foil technology to reduce sensitivity to ambient temperature variations and applied power changes.

Available now from TTI, SMR1DZ and SMR3DZ ultra-high-precision surface-mount resistors 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 with 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 5ohm to 80kohm, a low typical TCR of +/-0.05ppm/C from 0 to +60C and +/-0.2ppm/C from -55 to +125C 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.
