GS4A022671FFT

GS4A022671FFT Description

The GS4A022671FFT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation (ISOL circuit designator) in demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features thin-film technology for superior stability and accuracy, with a 2.67KΩ resistance value and a tight ±1% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C (derated) and delivers a 0.1W power rating per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures minimal drift, while the 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount assembly.

GS4A022671FFT Features

• Ceramic SOIC Package: Robust construction with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) for durability and thermal performance.
• Isolated Resistors: Four independent 2.67KΩ resistors with ±1% ratio tolerance, ideal for precision signal conditioning.
• High-Temperature Operation: Rated up to 125°C, making it suitable for industrial and automotive-adjacent environments (though not PPAP or Automotive certified).
• Low TCR: ±50ppm/°C ensures stable performance across temperature fluctuations.
• Surface-Mount Design: 1.27mm terminal pitch and gull-wing leads for reliable PCB integration.
