GQ0A035490JAT Description

The GQ0A035490JAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 10-resistor array features a 549 Ω resistance value per resistor with a 5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its isolated (ISOL) circuit design provides flexibility in circuit configurations.

GQ0A035490JAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal performance and mechanical durability in harsh environments.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
