GS4A021543GGT Description

The GS4A021543GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 154 kΩ and a tight tolerance of ±2%. The network operates within a temperature range of 70°C to 125°C and offers a low temperature coefficient of ±50 ppm/°C, ensuring stable performance under thermal stress. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, it is engineered for reliability in surface-mount applications. The SOIC package (4.9mm x 5.99mm x 1.45mm) provides a compact footprint, making it ideal for space-constrained designs.

GS4A021543GGT Features

• Isolated Resistors: Four independent resistors with isolated elements, reducing crosstalk and improving signal integrity.
• High Precision: ±2% absolute tolerance and ±2% ratio tolerance for consistent performance in matched circuits.
• Robust Construction: Ceramic case style ensures durability and thermal stability.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
• Surface-Mount Design: Gull-wing termination and 1.27mm terminal pitch for easy PCB integration.
