GS4A021103FAT Description

The GS4A021103FAT 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 110KΩ resistance and a tight ±1% absolute tolerance, ensuring exceptional accuracy. The network operates within a temperature range of 70°C to 125°C with a low temperature coefficient of ±50ppm/°C, providing stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers robust mechanical durability and reliable surface-mount compatibility. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this component is engineered for demanding circuits requiring isolation and precision.

GS4A021103FAT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) prevent crosstalk, ideal for signal isolation.
• High Precision: ±1% tolerance and ±0.05% ratio tolerance ensure minimal deviation in matched resistor pairs.
• Thermal Stability: ±50ppm/°C TCR maintains consistent performance across a -70°C to +125°C range.
• Robust Construction: Ceramic SOIC case enhances thermal dissipation and mechanical strength.
• Surface-Mount Ready: Gull-wing termination and 1.27mm pitch simplify PCB assembly.
• Derated Power Handling: Operates reliably at 125°C with derated power, suited for high-temperature environments.
