GS4A012000GT

GS4A012000GT Description

The GS4A012000GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 200Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient. Its thin-film technology ensures excellent stability and low noise, while the ceramic case provides superior thermal conductivity and durability. Rated for 0.1W per resistor (0.4W total), it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The gull-wing termination and 1.27mm pitch facilitate easy surface-mount assembly.

GS4A012000GT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Power Handling: 0.4W total power dissipation with derating up to 125°C.
• Precision Performance: ±2% absolute tolerance and ±100ppm/°C TCR ensure consistent operation under thermal stress.
• Robust Construction: Ceramic SOIC package offers excellent thermal management and mechanical strength.
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch comply with industry-standard PCB layouts.
• Wide Voltage Rating: Supports up to 100V, ideal for signal conditioning and divider networks.

GS4A012000GT Applications

This resistor network excels in precision analog circuits, industrial control systems, and automotive electronics (though not PPAP/AEC-Q200 qualified). Its isolated design is optimal for:

• Voltage dividers and gain-setting networks in op-amp circuits.
• Sensor signal conditioning where thermal stability is critical.
• Power supply feedback loops requiring low TCR drift.
• Test & measurement equipment demanding high accuracy over temperature.

Conclusion of GS4A012000GT

The GS4A012000GT combines precision, durability, and thermal resilience in a compact SOIC package, making it a reliable choice for engineers designing high-stability circuits. Its isolated thin-film resistors, ceramic construction, and wide operating range distinguish it from generic arrays, particularly in applications requiring long-term reliability under thermal cycling. While not automotive-grade, its performance suits industrial, medical, and instrumentation markets where accuracy and robustness are paramount.
