GS4A031471FAT Description

The GS4A031471FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 1.47KΩ and a tight ±1% absolute tolerance. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent durability and thermal conductivity. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for precision circuits requiring reliable isolation and minimal drift.

GS4A031471FAT Features

• Isolated Resistors: Four independent 1.47KΩ resistors with ±1% tolerance and ±0.05% ratio tolerance for precision matching.
• High Stability: ±25ppm/°C TCR ensures minimal resistance variation across temperatures.
• Robust Construction: Ceramic SOIC package with gull-wing terminations for superior thermal and mechanical performance.
• Surface-Mount Design: 8-pin narrow SOIC (4.9mm × 5.99mm × 1.45mm) with 1.27mm terminal pitch for compact PCB layouts.
• Wide Operating Range: Rated for -55°C to +125°C, derated to 70°C to 125°C at full power.
• Non-Automotive: Suitable for industrial and commercial applications but not PPAP-compliant.

GS4A031471FAT Applications

This resistor network excels in precision analog and digital circuits, including:

• Voltage Dividers: High-accuracy ratio tolerance (±0.05%) ensures consistent signal conditioning.
• Sensor Interfaces: Stable performance in temperature-sensitive environments (e.g., medical devices, test equipment).
• Isolation Circuits: Isolated resistors prevent crosstalk in multi-channel systems (e.g., data acquisition, instrumentation).
• Power Management: Reliable operation in DC/DC converters and feedback loops due to low TCR and high voltage tolerance.
