Vishay Releases SMN Series Resistor Networks

Vishay Intertechnology Inc. (Malvern, PA) announced the release of the SMN Series of four-resistor, surface-mount, ultra-precision, Bulk Metal® Foil resistor networks, which provide a low tracking TCR of 1ppm/°C and high stability of 0.01% at 0.1W in a small-outline, eight-pin, industry-standard, JEDEC MS-012 package.

Each SMN resistor network is made up of four independent Bulk Metal Foil resistors in a dual in-line, molded epoxy package measuring just 0.157in x 0.195in x 0.068in (3.99mm x 4.93mm x 1.73mm) and a 50-mil lead pitch. The compact, integrated construction provides TCR absolute values of ±5ppm/°C and a TCR tracking value of ±1ppm/°C. The devices also offer a broad range of resistance ratios from 1.0:1 to 100:1, with a tight resistance ratio tolerance of ±0.01% and absolute tolerance of ±0.02%. The power rating is 0.4W for the entire package at 70°C, or 0.1W per resistor.

Available in tube, waffle-pack, or tape-and-reel packaging, samples and production quantities of the SMN Series resistor networks are available now. Lead time for production quantities is approximately 12 weeks. Pricing for US delivery only in 100-piece quantities for devices with ±0.01% resistance ratio tolerance and TCR tracking of ±1ppm/°C typically is $15.
