GQ0A023092FT Description

The GQ0A023092FT 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 (1% tolerance) and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case provides excellent thermal stability and durability, while the gull-wing termination facilitates reliable PCB mounting. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for precision analog and digital circuits requiring tight tolerance and low drift.

GQ0A023092FT Features

• High Precision: 1% tolerance and ±50ppm/°C TCR ensure consistent performance in critical applications.
• Robust Construction: Ceramic case enhances thermal management and mechanical strength.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Surface-Mount Compatibility: QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density PCB layouts.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive environments (though non-automotive PPAP).
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring specific material properties.

GQ0A023092FT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Isolation Circuits: Buffering and impedance matching in communication interfaces (e.g., RS-485, CAN).
• Test & Measurement Equipment: Calibration and reference circuits demanding low drift.
• Industrial Controls: PLCs, sensor interfaces, and power management systems requiring high reliability.
• Medical Electronics: Isolated signal paths in diagnostic devices where accuracy is critical.
