GS4B012871CAT Description

The GS4B012871CAT 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. It features a 2.87KΩ resistance per element with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched circuits. The thin-film technology on a ceramic substrate delivers stable performance across a wide temperature range (70°C to 125°C), supported by a ±100ppm/°C temperature coefficient. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital systems.

GS4B012871CAT Features

• Bussed Network Design: 7 resistors connected in a bus configuration, simplifying PCB layout for common-node applications.
• High Precision: Tight tolerances (±0.25%) and low TCR (±100ppm/°C) ensure consistent performance in temperature-variable environments.
• Robust Construction: Ceramic case (SOIC package) with gull-wing terminations for mechanical durability and solderability.
• Space-Efficient: Compact dimensions (4.9mm × 5.99mm × 1.45mm) ideal for high-density designs.
• Wide Operating Range: Rated for 125°C maximum temperature, suitable for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).

GS4B012871CAT Applications
