GQ8A022871BBT Description

The GQ8A022871BBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 2.87KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing SMD termination and ceramic case provide robust mechanical and thermal performance, ideal for surface-mount assembly.

GQ8A022871BBT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50ppm/°C TCR for critical analog/digital signal conditioning.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) in a compact 4.9mm × 6.02mm × 1.47mm QSOP footprint.
• Isolation-Centric Design: Ceramic substrate enhances thermal conductivity and electrical isolation, reducing crosstalk.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Industrial-Grade Reliability: Non-automotive but suited for harsh environments due to ceramic construction.

GQ8A022871BBT Applications

• Precision Voltage Dividers: Used in ADC/DAC reference circuits where tolerance and TCR are critical.
• Medical Instrumentation: Isolation resistors for patient monitoring systems requiring high stability.
• Test & Measurement Equipment: Signal conditioning networks in oscilloscopes or multimeters.
• Aerospace & Defense: Avionics systems benefiting from ceramic packaging’s thermal resilience.
• Industrial Control Systems: Isolated feedback networks in motor drives or power supplies.

Conclusion of GQ8A022871BBT

The GQ8A022871BBT excels in high-precision, isolation-sensitive applications due to its thin film accuracy, ceramic robustness, and compact power density. While not RoHS-compliant, its 0.1% tolerance and ±50ppm/°C TCR outperform standard thick-film networks, making it ideal for mission-critical electronics. Engineers should verify unconfirmed part status but can leverage its QSOP gull-wing package for dense PCB layouts. A top choice for analog signal integrity in medical, industrial, and aerospace designs.
