GS4B019102CAT

GS4B019102CAT Description

The GS4B019102CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Built with ceramic thin-film technology, it offers a 91 kΩ resistance per element with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched circuits. The device operates over a wide temperature range (-70°C to +125°C) with a ±100 ppm/°C temperature coefficient, maintaining stability in harsh environments. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital systems.

GS4B019102CAT Features

• Ceramic SOIC Construction: Robust rectangular package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminals for reliable SMT assembly.
• Bussed Network Design: Simplifies PCB layout by integrating 7 resistors with a common BUS connection.
• Ultra-Tight Tolerances: ±0.25% absolute and ±0.05% ratio tolerance for precision voltage division and signal conditioning.
