GS4A0227R4FCT Description

The GS4A0227R4FCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 27.4Ω resistance and a tight ±1% absolute tolerance, ensuring exceptional accuracy. The device operates over a wide temperature range (70°C to 125°C) with a ±50ppm/°C temperature coefficient, making it suitable for stable performance in varying thermal conditions. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it balances power handling and compactness. The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB integration.

GS4A0227R4FCT Features

• Isolated Resistors: Four independent resistors in a single SOIC package, eliminating crosstalk.
• High Precision: ±1% absolute tolerance and ±0.25% ratio tolerance for critical analog circuits.
