GQ0A023092CT Description

The GQ0A023092CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 30.9kΩ resistance value and an ultra-tight ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability across a wide temperature range of -70°C to +125°C. With a ±50ppm/°C temperature coefficient, 1W total power rating (0.1W per resistor), and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits requiring minimal drift and high isolation.

GQ0A023092CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR ensure consistent performance in critical applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal dissipation and long-term stability.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk, ideal for signal isolation.
• Space-Efficient: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm gull-wing pitch enables high-density PCB layouts.
• Wide Operating Range: Rated for -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
• Non-RoHS Compliant: Preferred for legacy or high-reliability systems requiring leaded terminations.

GQ0A023092CT Applications

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Isolation Circuits: Medical equipment, industrial sensors, and test instrumentation where signal integrity is critical.
• Communication Systems: Impedance matching and termination in high-speed data lines.
• Power Management: Current sensing and shunt applications in power supplies.
• Legacy Electronics: Military/aerospace systems requiring non-RoHS compliant components.
