GS4B031432FBT Description

The GS4B031432FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 14.3KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this BUS-designated network is ideal for precision analog and digital circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal and mechanical durability.

GS4B031432FBT Features

• Thin Film Technology: Delivers superior accuracy and stability vs. thick-film alternatives.
• Ceramic Case: Enhances heat dissipation and reliability in harsh environments.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress.
• High Power Density: 0.4W total rating in a compact 4.9mm × 5.99mm × 1.45mm footprint.
• Automated Assembly-Friendly: Gull-wing leads and standardized SOIC package streamline SMT processes.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.
