GQ8A025490BAT Description

The GQ8A025490BAT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers a 549 Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for applications requiring electrical separation. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network excels in precision analog and mixed-signal circuits.

GQ8A025490BAT Features

• High Precision: 0.1% tolerance and ±50 ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Ceramic case with gull-wing SMD termination ensures durability and reliable surface-mount assembly.
• Isolated Design: Independent resistors (ISOL) prevent crosstalk, critical for sensitive signal paths.
• Compact & Reliable: QSOP package (4.9mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances for space-constrained PCBs.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive: Optimized for general-purpose use, though not PPAP-capable or automotive-grade.
