Malvern, Pa. Once again Vishay Intertechnology, Inc. has made it clear who is the technology leader in the thin-film passive components market with the introduction of its MP series of precision thin-film resistor divider networks. Vishay said these are the first resistor divider networks to offer a 0.05% resistance ratio tolerance in an ultra-small SC-70 package. These devices are designed for use in instrumentation amplifiers, precision voltage dividers, and bridge network circuitry.
Combining small size with a low ratio tolerance, these divider resistor networks provide an alternative to larger-format devices packaged in the SOT-23 or SOT-143 case sizes. Optimized for industrial control systems, handheld instruments such as portable measuring devices for diagnostics, and other end systems requiring precision resistor pairs with small dimensions, these surface-mount devices provide precision tolerances down to 0.05% in the industry's smallest standard package.
The MP devices are available as isolated matched-pair or center-tapped resistor divider networks in 3-lead (MP3) or 4-lead (MP4) standard molded SC-70 packages with maximum dimensions of 2.200 x 1.350 mm with a height profile of 1.100 mm. The new networks feature low temperature coefficient ratio (TCR) tracking of ±2 ppm/°C and resistance values ranging from 1 kilohm to 10 kilohms per resistor. Custom designs are available for applications requiring non-standard ratios, and custom resistance values are available to 50 kilohms.
Each network is specified for a TCR value of ±25 ppm/°C and a power rating of 0.075 W per resistor or 0.150 W for the package. A TAMELOX (passivated nichrome) resistive layer enhances stability with long-term stability rated for 500 ppm at 70°C for 2,000 hours. Shelf-life stability is specified at less than 100 ppm at 25°C for one year. The operating temperature range is -55°C to 125°C.
