GS4A034220FAT Description

The GS4A034220FAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors with a resistance value of 422Ω, offering an absolute tolerance of ±1% and an exceptional ratio tolerance of ±0.05%. The device operates within a temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, ensuring stability under thermal stress. Its 0.1W (1/10) power rating per resistor and 100V maximum voltage rating make it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal performance.
