GS8B034990JBT Description

The GS8B034990JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in a 16-pin narrow SOIC package, this bussed network integrates 15 resistors with a 499Ω value and ±5% absolute tolerance, ensuring reliable signal integrity. Its thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing termination, optimized for surface-mount assembly. Rated for 100V maximum voltage and 0.8W total power dissipation, it operates across a 70°C to 125°C derated range, with a 125°C maximum operating temperature.

GS8B034990JBT Features

• Precision Engineering: ±0.1% ratio tolerance ensures minimal deviation between resistors, critical for balanced circuits.
• Robust Construction: Ceramic substrate enhances thermal stability and durability compared to polymer-based networks.
• Space-Efficient: Compact 9.91mm × 5.99mm × 1.45mm footprint (SOIC-16) saves PCB real estate.
• High Power Handling: 0.05W per resistor (1/20W) and 0.8W total rating support moderate-power applications.
• Wide Voltage Range: 100V rating accommodates industrial and automotive-grade designs (though non-automotive PPAP).
• Stable Performance: ±25ppm/°C TCR minimizes resistance drift under temperature stress.

GS8B034990JBT Applications
