GS4A031800GDT Description

The GS4A031800GDT 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 180Ω resistance value and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating range of 70°C to 125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic case enhances thermal and mechanical reliability. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network balances precision and durability.
