GS4B022801CAT Description

The GS4B022801CAT 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 substrate and thin-film technology, it offers a 2.8KΩ resistance value with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring superior accuracy in signal conditioning and voltage division circuits. The device operates over a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, making it ideal for environments with thermal fluctuations. Its 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) provide robust performance in compact designs.

GS4B022801CAT Features

• Precision Network: 7 bussed resistors with ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case (SOIC package) ensures durability and thermal stability.
• High-Density Design: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm gull-wing pitch for space-constrained PCBs.
