GQ8A017870BAT Description

The GQ8A017870BAT 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 787Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal performance and durability.

GQ8A017870BAT Features

• Precision Thin Film Technology: Delivers 0.1% tolerance and ±100ppm/°C TCR for critical analog/digital systems.
• Robust Ceramic QSOP Package: Provides superior thermal dissipation and mechanical strength vs. plastic alternatives.
• Isolation-Centric Design: Circuit designator "ISOL" indicates optimized performance for isolated signal paths.
• High Power Handling: 0.75W total rating (0.1W per resistor) at 125°C max temperature, derated for extended reliability.
• Strict Dimensional Tolerances: ±0.1mm height/length and ±0.2mm depth ensure consistent PCB fit.
• Non-Automotive (PPAP No): Ideal for industrial, medical, and telecom applications requiring precision without automotive certification.
