GS4B023090FFT

GS4B023090FFT Description

The GS4B023090FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 309Ω resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. The thin-film technology delivers excellent stability with a low ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and surface-mount gull-wing termination suit compact, high-density PCB designs.

GS4B023090FFT Features

• Ceramic case for enhanced thermal and mechanical stability.
• Bussed network topology simplifies circuit design by connecting resistors in a common configuration.
• Precision thin-film resistors with ±1% tolerance and ±50ppm/°C TCR for minimal drift.
• SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances for consistent mounting.
• Gull-wing leads (1.27mm pitch) ensure reliable soldering in automated assembly.
• Non-automotive (PPAP No) and EU RoHS non-compliant, restricting use in certain regulated applications.
