GQ8A011303BBT Description

The GQ8A011303BBT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers 130K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount (SMD) device combines reliability with compactness, suited for space-constrained PCB layouts.

GQ8A011303BBT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic case and gull-wing terminations ensure durability and solderability.
• Isolated Design: Independent resistors (ISOL) prevent signal interference, critical for sensitive circuits.
• Compact & Efficient: QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm pitch for high-density mounting.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade applications (though non-PPAP).
• Non-RoHS: May be preferred for legacy or high-reliability systems requiring leaded components.

GQ8A011303BBT Applications

• Precision Instrumentation: Signal conditioning in data acquisition systems and medical devices.
• Industrial Controls: Isolation in PLCs, motor drives, and power management circuits.
• Telecom & Networking: Impedance matching and termination in high-speed communication PCBs.
• Aerospace & Defense: Reliable performance in harsh environments due to ceramic encapsulation.
• Legacy Systems Maintenance: Non-RoHS compliance aligns with older design requirements.
