GQ8A011373DAT

GQ8A011373DAT Description

The GQ8A011373DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 137K Ohm resistance value with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and instrumentation circuits.

GQ8A011373DAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Ceramic QSOP Case: Provides superior thermal management and mechanical robustness compared to plastic packages.
• Isolated Circuit Design (ISOL): Ensures minimal crosstalk between resistors, ideal for multi-channel systems.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
• Strict Tolerances: ±0.1mm length/height and ±0.2mm depth tolerances ensure consistent PCB fit.
• Non-Automotive (PPAP No): Optimized for industrial, medical, and test equipment applications.
