GS4B035490FDT Description

The GS4B035490FDT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC gull-wing SMD package. Designed for surface-mount applications, it features a 549Ω resistance per element 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 case and thin film technology provide excellent thermal stability and low noise, making it ideal for precision analog and digital circuits. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness (4.9mm × 5.99mm × 1.45mm) with robustness. Packaged in a tube, it suits automated assembly processes.

GS4B035490FDT Features

• Precision Network: 7 resistors, each 549Ω ±1%, with ±25ppm/°C TCR for minimal drift.
• High Reliability: Ceramic substrate and thin film construction ensure long-term stability.
• Compact & Robust: SOIC-8 package (4.9mm × 5.99mm × 1.45mm) with gull-wing leads for secure SMT mounting.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Automation-Friendly: Tube packaging streamlines pick-and-place assembly.
• Non-Automotive: PPAP non-compliant, best for industrial/commercial use.

GS4B035490FDT Applications
