GS4B0266R5JT

GS4B0266R5JT Description

The GS4B0266R5JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 7-resistor bussed network features a 66.5Ω resistance per element with a tight ±5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology provides excellent power handling (0.4W total, 0.05W per resistor) and a maximum voltage rating of 100V, making it suitable for high-density PCB designs.
