GS4A026191GT

GS4A026191GT Description

The GS4A026191GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 6.19 kΩ resistance and a tight ±2% tolerance. Its ±50 ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it suitable for environments with significant thermal fluctuations. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) offers a compact footprint with gull-wing terminations for reliable surface-mount assembly. Rated for 100 V maximum voltage and 0.1 W power dissipation per resistor, it balances durability with efficiency.

GS4A026191GT Features

• Isolated Resistor Network: Four independent resistors in a single package, eliminating crosstalk for critical signal integrity.
• High Stability: Thin-film technology and ceramic case provide superior thermal and mechanical robustness.
• Precision Performance: ±2% absolute tolerance and ±50 ppm/°C TCR ensure consistent operation in precision circuits.
• Compact & Reliable: SOIC-C series design with 1.27 mm terminal pitch optimizes PCB space while supporting automated assembly.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).

GS4A026191GT Applications

Ideal for analog signal conditioning, voltage division, and impedance matching in:

• Industrial Control Systems: Stable performance in PLCs and sensor interfaces.
• Medical Electronics: Precision circuits where resistance stability is critical (e.g., patient monitoring).
• Automotive Modules: Non-automotive grade but suitable for benign-environment subsystems like infotainment.
• Test & Measurement Equipment: High-accuracy dividers and calibration networks.

Conclusion of GS4A026191GT

The GS4A026191GT excels in applications demanding miniaturization, thermal stability, and electrical isolation. Its ceramic construction, thin-film resistors, and tight tolerances make it a superior choice over epoxy-based networks or less stable thick-film alternatives. While not PPAP or automotive-qualified, it is a cost-effective solution for industrial and medical designs where precision and reliability are paramount. The tube packaging ensures handling safety during high-volume production.
