GS4B037871FBT Description

The GS4B037871FBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC package, designed for surface-mount applications. With a 7.87KΩ resistance value and tight 1% tolerance, it ensures reliable performance in precision circuits. The ceramic case and thin-film technology provide excellent stability, with a low ±25ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it operates reliably within a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature.

GS4B037871FBT Features

• 7-resistor BUS configuration in a compact SOIC-8 package (4.9mm × 5.99mm × 1.45mm).
• Thin-film technology ensures high accuracy (±1%) and low TCR (±25ppm/°C).
• Ceramic substrate enhances thermal stability and durability.
• Gull-wing termination for secure SMD mounting with 1.27mm terminal pitch.
• 0.4W total power rating, derated for high-temperature operation (up to 125°C).
• Non-automotive, non-PPAP compliant, ideal for industrial and commercial applications.
• Tube packaging for safe handling and storage.
