Vishay Intertechnology Inc. has added 16-pin and 24-pin versions to its OSOP series of surface-mount dual in-line thin film resistor networks in the 25mil pitch QSOP package. The new Vishay Dale Thin Film networks complies with JEDEC MO-137, variation AB and AE.

The thin film networks come in isolated, last pin common and custom schematics, featuring tight ratio tolerances to ±0.025% and low TCR tracking of ± 5 ppm/°C to deliver higher precision than competing devices, Vishay said.

Optimised for precision voltage dividers and operational amplifiers, the resistor networks offer a low (1.73mm) maximum seated height, while their 25mil pitch allows designers to reduce board space requirements by more than 50% over current pitch standards. Applications for the networks include telecommunications, industrial, process control and medical instrumentation.

In isolated schematics, the 16-pin and 24-pin networks are available with 8 or 12 resistors, respectively, each with resistance values from 500Ω to 100kΩ and power ratings to 100mW. In last pin common schematics, the devices are offered with 7 or 11 resistors. Featuring a rugged moulded case construction with no internal solder, the networks provide absolute TCR of ±25ppm/°C and ratio stability of ±0.015% for 2,000 hours at 70°C.

The devices feature low noise of <-30dB, voltage coefficients of less than 0.1ppm/V and they operate over a temperature range of -55°C to 125°C. The OSOP series is RoHS-compliant and halogen-free.

Samples and production quantities of the resistor networks are available now, with lead times of 5 to 10 weeks for larger orders.
