GQ8A0352R3JT

GQ8A0352R3JT Description

The GQ8A0352R3JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 52.3Ω resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 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 (1/10W) per resistor, making it suitable for demanding circuit designs. The gull-wing termination and surface-mount (SMD) design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A0352R3JT Features

• Precision Thin Film Technology: Delivers stable resistance with ±25ppm/°C TCR for minimal drift under thermal stress.
• High Power Handling: 0.75W total power rating (0.1W per resistor) ensures robustness in compact designs.
