GS4B031271FT Description

The GS4B031271FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 1.27KΩ resistance per element with a tight ±1% tolerance, this thin-film ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, suitable for compact, high-density PCB designs.

GS4B031271FT Features

• Bussed Network Topology: Simplifies circuit design by connecting resistors in a shared configuration.
• High Stability: Ceramic substrate and thin-film technology ensure low noise and long-term reliability.
• Precision Performance: ±1% absolute tolerance and ±25ppm/°C TCR for critical analog/digital applications.
• Robust Packaging: 8-pin SOIC (4.9mm × 5.99mm × 1.45mm) with gull-wing leads for secure SMT assembly.
• Derated Power Handling: Operates at 70–125°C with derated power, exceeding standard industrial requirements.
• Non-Automotive Grade: Optimized for industrial, telecom, and instrumentation use (PPAP not required).

GS4B031271FT Applications

• Voltage Division/Current Limiting: Precision dividers in ADC/DAC reference circuits.
• Signal Conditioning: Pull-up/pull-down networks in microcontroller I/O interfaces.
• Power Management: Load balancing in low-power DC/DC converters.
