GS4B021212FT Description

The GS4B021212FT from TT Electronics/IRC is a high-performance 7-resistor bussed network housed in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 12.1KΩ resistance per element with a tight ±1% absolute tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination enable robust surface-mount integration in space-constrained designs.

GS4B021212FT Features

• Ceramic Case (SOIC-C): Enhances thermal performance and durability in harsh environments.
• Bussed Network (BUS): Simplifies circuit design by interconnecting resistors, reducing component count.
• Precision Thin Film: Delivers ±1% tolerance and ±50ppm/°C TCR for stable performance.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Compact & Robust: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions with ±0.1mm height/length tolerances.
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch for easy PCB assembly.
• Non-Automotive: Ideal for industrial, telecom, and instrumentation applications.
