GS4A0228R0DT Description

The GS4A0228R0DT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. This ceramic-based thin-film resistor network offers a 28Ω resistance per element with an exceptional ±0.5% absolute tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The SOIC-C series construction provides robust performance with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits.

GS4A0228R0DT Features

• Isolated Resistor Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Precision: ±0.5% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic substrate and thin-film technology deliver superior thermal and long-term stability.
• Surface-Mount Compatibility: Gull-wing termination and 1.27mm pitch facilitate easy PCB integration.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Compact Footprint: Measures just 4.9mm (L) × 5.99mm (D) × 1.45mm (H), ideal for space-constrained designs.
