Available With Isolated, Last Pin Common, and Custom Schematics in 25 mil Pitch QSOP Package, Devices Offer Tight Ratio Tolerances to ± 0.025 %
Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the company has extended its OSOP series of surface-mount dual in-line thin film resistor networks in the 25 mil pitch QSOP package with new 16-pin and 24-pin versions in accordance with JEDEC MO-137, variation AB and AE. Available in isolated, last pin common, and custom schematics, the Vishay Dale Thin Film networks feature tight ratio tolerances to ± 0.025 % and low TCR tracking of ± 5 ppm/°C to deliver higher precision than competing devices. Optimized for precision voltage dividers and operational amplifiers, the resistor networks released today feature a low 1.73 mm maximum seated height, while their 25 mil pitch allows designers to reduce board space requirements by more than 50 % over current pitch standards. Typical applications will 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 500 Ω to 100 kΩ and power ratings to 100 mW. In last pin common schematics, the devices are offered with 7 or 11 resistors. Featuring a rugged molded case construction with no internal solder, the networks provide absolute TCR of ± 25 ppm/°C and ratio stability of ± 0.015 % for 2,000 hours at 70 °C.
The devices feature extremely low noise of < -30 dB and voltage coefficients of less than 0.1 ppm/V, and they operate over a wide temperature range of -55 °C to +125 °C. The OSOP series is RoHS-compliant and halogen-free.
Samples and production quantities of the new resistor networks are available now, with lead times of 5 to 10 weeks for larger orders. Pricing for U.S. delivery ranges from $1.09 to $4.03 per piece and varies by ratio tolerance and package size.
