GS4B015491GFT Description

The GS4B015491GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 5.49KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched-resistor applications. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust operation in compact designs.

GS4B015491GFT Features

• Ceramic Case & Thin Film Technology: Ensures high stability, low noise, and excellent thermal performance.
• Bussed Network (BUS Designator): Simplifies circuit design by connecting resistors in a common configuration.
• Precision Tolerances: ±2% absolute and ±1% ratio tolerance for critical analog/digital signal conditioning.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Compact SOIC Package: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with gull-wing termination for reliable surface-mount assembly.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.
