GS4B021781FT Description

The GS4B021781FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 7-resistor bussed network features a 1.78KΩ resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable PCB mounting. The thin-film technology provides excellent power handling (0.4W total, 0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits.

GS4B021781FT Features

• Bussed Network Design: 7 resistors connected in a bus configuration, simplifying circuit layout.
• High Stability: ±50ppm/°C TCR and ±1% tolerance ensure minimal drift in harsh environments.
