GQ8A031303BBT Description

The GQ8A031303BBT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it features 130K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration offers robust surface-mount compatibility, while the isolated (ISOL) circuit design minimizes crosstalk. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances compactness (4.9mm × 6.02mm × 1.47mm) with reliability in harsh environments.

GQ8A031303BBT Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR for critical analog/digital systems.
• Robust Construction: Ceramic case and thin-film technology ensure durability and thermal stability.
• High-Density Design: QSOP-16 package with 0.64mm pitch, ideal for space-constrained PCBs.
• Isolated Resistors: Independent elements (ISOL) prevent signal interference in multi-channel designs.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power at elevated temperatures.
• Automated Assembly Friendly: Gull-wing terminals and tube packaging streamline SMT processes.

GQ8A031303BBT Applications

• Medical Equipment: Precision voltage dividers in patient monitoring systems.
• Industrial Automation: Signal isolation in PLCs and sensor interfaces.
• Telecom Infrastructure: Impedance matching in high-frequency RF modules.
• Test & Measurement: Calibration circuits requiring drift-free resistance.
