GS4B021871BAT Description

The GS4B021871BAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding circuit applications. This ceramic-based thin-film resistor network offers a 1.87KΩ resistance per element with an exceptional ±0.1% absolute tolerance and ±0.05% ratio tolerance, ensuring superior accuracy in signal conditioning and voltage division. Rated for 0.4W total power dissipation (0.05W per resistor) and operating within a -70°C to +125°C temperature range, it is engineered for stability in harsh environments. The SOIC-C series construction features gull-wing terminations with a 1.27mm pitch, facilitating reliable surface-mount assembly.

GS4B021871BAT Features

• Precision Performance: Ultra-tight tolerances (±0.1%) and low ±50ppm/°C TCR minimize drift in critical analog circuits.
• Robust Construction: Ceramic substrate enhances thermal management and durability under high-voltage (100V max) conditions.
• Space-Efficient Design: Compact 4.9mm × 5.99mm × 1.45mm footprint (SOIC-8) optimizes PCB real estate.
• Bussed Topology: Simplified bus connections reduce layout complexity in voltage divider and bus termination applications.
• Industrial-Grade Reliability: Non-automotive but suited for industrial controls, test equipment, and telecom infrastructure.
