GS4A012001GT

GS4A012001GT Description

The GS4A012001GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 4-resistor isolated network features a 2KΩ resistance per element with a tight ±2% absolute tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C derated power range. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for surface-mount assembly. The thin-film technology provides superior stability and low noise, while the 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for moderate-power circuits.

GS4A012001GT Features

• Isolated Resistor Configuration: Four independent 2KΩ resistors for flexible circuit design.
• High-Temperature Stability: Operates up to 125°C with minimal drift (±100ppm/°C).
• Precision Tolerance: ±2% absolute tolerance ensures consistent performance.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• Surface-Mount Ready: Gull-wing terminations and 1.27mm pitch for easy PCB integration.
• Low-Power Efficiency: 0.4W total power dissipation (0.1W per resistor).
• Non-Automotive (PPAP No): Ideal for industrial and commercial applications.

GS4A012001GT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in analog circuits.
• Sensor Interfaces: Stable biasing for thermocouples, RTDs, and strain gauges.
• Medical Electronics: Low-noise, high-reliability systems like patient monitors.
• Test & Measurement Equipment: Calibration circuits requiring minimal thermal drift.
• Industrial Controls: Isolated signal paths in PLCs and motor drives.
