GS4A0228R7GDT Description

The GS4A0228R7GDT 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, each with a resistance value of 28.7Ω and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and ±0.5% ratio tolerance make it ideal for applications requiring stable and matched resistances. With a maximum voltage rating of 100V and a power rating of 0.1W per resistor (0.4W total), this network is suited for both industrial and commercial circuits.

GS4A0228R7GDT Features

• Isolated Resistor Design: Four independent resistors in a single package, reducing board space and simplifying layout.
• High Precision: ±2% absolute tolerance and ±0.5% ratio tolerance ensure consistent performance in differential circuits.
• Robust Construction: Ceramic substrate and thin-film technology provide excellent thermal stability and low noise.
• Wide Operating Range: -55°C to +125°C with derated power up to 125°C, suitable for harsh environments.
• Surface-Mount Gull Wing Terminals: 1.27mm pitch for easy PCB integration and automated assembly.
• Low TCR: ±50ppm/°C minimizes resistance drift over temperature variations.
