GS4B022210FFT

GS4B022210FFT Description

The GS4B022210FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC (SOIC-C series) device integrates 7 bussed resistors, each with a 221Ω resistance and a tight ±1% absolute tolerance. Built using thin-film technology, it delivers excellent stability with a low ±50ppm/°C temperature coefficient. The network operates over a wide temperature range (-70°C to +125°C) and supports a maximum voltage rating of 100V, making it suitable for demanding environments. Encased in a rectangular ceramic package, it offers superior thermal performance and durability compared to polymer-based alternatives.

GS4B022210FFT Features

• High Precision: ±1% tolerance and ±50ppm/°C TCR ensure consistent performance.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch for high-density PCB layouts.
• Power Handling: 0.4W total power rating (0.05W per resistor) at derated power up to 125°C.
• Bussed Configuration: Simplifies circuit design by connecting multiple resistors to a common node (BUS).
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints for automated assembly.
