GQ8A012202DBT Description

The GQ8A012202DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 22KΩ resistance value per resistor with an exceptional ±0.5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, making it ideal for precision analog and digital circuits.

GQ8A012202DBT Features

• High Precision: Tight tolerance (±0.5%) and low TCR (±100ppm/°C) for reliable signal conditioning.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Compact & Efficient: 4.9mm × 6.02mm × 1.47mm footprint with gull-wing terminations for easy PCB integration.
• Power Handling: 0.1W per resistor (0.75W total) and 100V max rating, suitable for medium-power applications.
• Isolated Design: ISOL circuit configuration prevents crosstalk, ideal for multi-channel systems.
• Non-Automotive Grade: Compliant with EAR99 (ECCN) but not PPAP or RoHS certified.

GQ8A012202DBT Applications

• Precision Instrumentation: Voltage dividers, feedback networks in op-amps, and DAC/ADC circuits.
• Industrial Controls: Signal conditioning in PLCs, motor drivers, and sensor interfaces.
• Telecom & Networking: Impedance matching and termination in high-frequency PCBs.
• Medical Devices: Low-noise analog front-ends where stability is critical.
• Test & Measurement Equipment: Calibration circuits requiring long-term drift resistance.
