Vishay Releases MP Series Resistor Divider Networks


New Products Aug 02, 2004 by Jeff Shepard

Vishay Intertechnology Inc. (Malvern, PA) released its new MP Series of precision thin-film resistor divider networks that offer 0.05% resistance ratio tolerance in the ultra-small SC-70 package. Intended for use in instrumentation amplifiers, precision voltage dividers, and bridge network circuitry, the MP Series are optimized for industrial control systems, hand-held instruments such as portable measuring devices for diagnostics, and other end systems requiring precision resistor pairs with small dimensions.

The MP devices are available as isolated matched-pair or center-tapped resistor divider networks in three-lead or four-lead standard molded SC-70 packages with maximum dimensions of 2.200 mm x 1.350 mm x 1.100 mm. The networks feature low temperature coefficient ratio (TCR) tracking of ±2 ppm/°C, and the standard SC-70 package format provides common standard resistance values ranging from 1 kilohm to 10 kilohms per resistor.

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. Long-term stability is rated for 500 ppm at 70 °C for 2,000 hours, and shelf-life stability is specified at less than 100 ppm at 25 °C for one year. The devices' operating temperature range is from -55 °C to +125 °C.

Samples and production quantities of the new devices are available now, with a lead time of eight weeks for larger orders. Custom values are available to a resistance value of 50 kilohms. Pricing for US delivery in 1,000-piece quantities is $1.65 per piece.
