New models of Vishay OSOP series SMD dual in-line thin film network resistors with higher precision
Vishay Intertechnology, Inc. has recently launched new 16-pin and 24-pin versions of its OSOP series surface mount dual in-line thin film network resistors, now compliant with JEDEC MO-137 variation AB and AE. These advanced components are housed in a 25 mil pitch QSOP package, offering enhanced performance and precision for demanding applications.
The Vishay Dale thin film network resistors feature an isolated or shared final pin configuration, with resistance tolerances as tight as ±0.025% and a temperature coefficient of resistance (TCR) of ±5ppm/°C—outperforming many competitive options. This level of accuracy makes them ideal for precision voltage dividers and operational amplifiers.
Designed for compact designs, these resistors have a maximum height of 1.73mm and a 25 mil pitch, using 50% less board space compared to standard devices. They are well-suited for use in telecommunications, industrial automation, process control systems, and medical equipment where reliability and performance are critical.
In isolated configurations, the 16-pin and 24-pin networks include 8 or 12 resistors, ranging from 500Ω to 100kΩ with a power rating of 100mW. In shared pin configurations, they offer 7 or 11 resistors. The design includes a durable molded case without solder paste, ensuring long-term stability and reliability.
These resistors exhibit an absolute TCR of ±25ppm/°C and can maintain a resistance ratio of ±0.015% at 70°C for up to 2000 hours. Their noise level is exceptionally low, below -30dB, and the voltage coefficient is under 0.1ppm/V. The operating temperature range spans from -55°C to +125°C, making them suitable for extreme environments.
The OSOP series is RoHS compliant and free from halogens, aligning with environmental standards. Samples are currently available, and the product is in full-scale production. For larger orders, lead times range from five to ten weeks, allowing for smooth integration into manufacturing processes.
