GS4B029101BAT

GS4B029101BAT Description

The GS4B029101BAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C Series) package. Designed for demanding applications, it features a 9.1KΩ resistance per element with an exceptional ±0.1% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched circuits. The network employs thin-film technology on a ceramic substrate, delivering stable performance across a wide temperature range (70°C to 125°C) with a low ±50ppm/°C temperature coefficient. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital systems.

GS4B029101BAT Features

• High Precision: ±0.1% tolerance and ±50ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic case with gull-wing termination for reliable surface-mount (SMD) assembly.
• Compact Design: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) footprint, ideal for space-constrained PCBs.
• Bussed Architecture: Simplifies circuit design by connecting resistors to a common node (BUS).
• Wide Operating Range: Rated for 125°C maximum temperature, suitable for industrial environments.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-qualified.

GS4B029101BAT Applications
