GQ8A029090GBT Description

The GQ8A029090GBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Encased in a ceramic QSOP package, it offers a 909Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, this 16-pin surface-mount device (SMD) is ideal for demanding circuits requiring high voltage isolation (100V max) and reliable thermal management.

GQ8A029090GBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Enhances thermal conductivity and mechanical durability vs. plastic alternatives.
• Isolated Resistor Network (ISOL): Prevents crosstalk in multi-channel systems, critical for signal integrity.
• Gull Wing Termination: Ensures robust solder joints for automated PCB assembly.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive (non-AECQ) environments.
• Non-RoHS Compliant: Preferred for legacy or high-reliability systems where lead-free alternatives may compromise performance.

GQ8A029090GBT Applications

• Signal Conditioning: Isolated voltage dividers in data acquisition systems.
• Medical Equipment: Precision impedance matching in patient monitoring devices.
