GS4A031271FT Description

The GS4A031271FT 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 1.27 kΩ resistance and a tight ±1% tolerance. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25 ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent durability and heat dissipation, making it suitable for high-reliability environments. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this component is engineered for precision signal conditioning and voltage division tasks.

GS4A031271FT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) prevent crosstalk, ideal for multi-channel systems.
• High Stability: ±25 ppm/°C TCR and 1% tolerance ensure minimal drift in precision applications.
• Robust Construction: Ceramic case enhances thermal performance and mechanical strength.
• Surface-Mount Ready: Gull-wing termination and 1.27mm pitch simplify PCB assembly.
• Wide Operating Range: Functions reliably from -55°C to 125°C (derated power up to 125°C).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4A031271FT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring low drift.
• Industrial Controls: PLCs, motor drives, and instrumentation where isolation and stability are critical.
• Telecommunications: Signal conditioning in RF and baseband systems.
• Medical Devices: High-accuracy measurement equipment.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems (note: not PPAP/automotive certified).
