GS4B032870FCT Description

The GS4B032870FCT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC gull-wing SMD package, designed for BUS circuit applications. It features a 287Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic-based construction and 0.4W total power rating (0.05W per resistor) make it suitable for demanding environments. With a 100V maximum voltage rating and surface-mount (SOIC) packaging, it combines reliability with space efficiency.

GS4B032870FCT Features

• Precision Thin Film Technology: Delivers low TCR (±25ppm/°C) and 1% tolerance for accurate signal conditioning.
• Robust Ceramic Case: Enhances thermal stability and mechanical durability.
• High-Density Integration: 7 resistors in a compact 4.9mm × 5.99mm × 1.45mm SOIC package.
• Gull-Wing Termination: Facilitates reliable soldering in automated SMT processes.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Non-Automotive (PPAP No): Ideal for industrial and telecom applications.
