Vishay Intertechnology Inc. has announced the release of the SMN series of four-resistor, surface-mount Bulk Metal Foil resistor networks that may be used independently or as divider pairs in precision instrumentation amplifiers, differential amplifier gain controls, and matched references in automated test equipment and measurement instrumentation.

Claimed by the company as the industry's first to provide 1ppm/C tracking TCR, 5ppm/C TCR absolute value, and 0.01 percent stability at 0.1W, the products are offered in an eight-pin, industry-standard JEDEC MS-012 package that measures 3.99-by-4.93-by-1.73mm with 50-mil lead pitch.

Eight resistance values between 100 ohms and 10,000 ohms allow the series to offer a broad range of resistance ratios from 1.0:1 to 100:1, with a tight resistance ratio tolerance of 0.01 percent and absolute tolerance of 0.02 percent. The power rating is 0.4W for the entire package at 70C, or 0.1W per resistor.

Featuring a 0.04?V/C thermal EMF and 0.01?V/V current noise at -40dB, the product is available in tube, waffle-pack, or tape-and-reel packaging. Lead time is 12 weeks.
