GS4A011581FT Description

The GS4A011581FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 1.58KΩ and a tight ±1% tolerance. The network operates within a wide temperature range of 70°C to 125°C, with a ±100ppm/°C temperature coefficient, ensuring stability under varying thermal conditions. Encased in a rectangular SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 0.1W per resistor (0.4W total) and a maximum voltage of 100V, it is ideal for high-density PCB designs requiring precision and durability.
