GS4A021051GGT

GS4A021051GGT Description

The GS4A021051GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 1.05 kΩ resistance and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±50 ppm/°C, ensuring stable performance under thermal stress. Its SOIC-C series construction offers excellent power dissipation (0.1W per resistor, 0.4W total) and a maximum voltage rating of 100V, making 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 management.

GS4A021051GGT Features

• Isolated Resistors: Four independent 1.05 kΩ resistors with ±2% absolute and ratio tolerance for precise matching.
• High Stability: ±50 ppm/°C TCR and 125°C maximum operating temperature ensure reliability in harsh environments.
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances for consistent mounting.
• Power Efficiency: 0.1W per resistor (0.4W total) derated up to 125°C, ideal for compact designs.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for automated assembly compatibility.

GS4A021051GGT Applications

This resistor network excels in precision analog circuits, signal conditioning, and voltage division where tight tolerance and thermal stability are critical. Key use cases include:

• Industrial Sensors: Stable resistance for bridge networks in pressure/temperature sensors.
• Medical Electronics: Low-drift performance in diagnostic equipment.
• Automotive ECUs (non-automotive grade): Robustness for under-hood modules (though not PPAP/automotive-certified).
• Test & Measurement: High-accuracy dividers and calibration circuits.

Conclusion of GS4A021051GGT

The GS4A021051GGT stands out for its precision, thermal resilience, and compact SOIC footprint, making it a superior choice over generic resistor arrays.
