GQ8B019090JAT Description

The GQ8B019090JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 15-resistor array features a 909 Ohm resistance value with a 5% tolerance and a ±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 a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, making it suitable for compact, high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while the 100V maximum voltage rating enhances reliability in demanding circuits.

GQ8B019090JAT Features

• Ceramic Case Style: Provides excellent thermal stability and mechanical durability.
• Thin-Film Technology: Delivers low noise and high precision for sensitive analog/digital circuits.
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down applications.
• Non-Automotive, Non-PPAP: Ideal for industrial, telecom, and consumer electronics where automotive-grade certification is not required.
