GQ8A022102BBT Description

The GQ8A022102BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation circuit applications. This 8-resistor array features a 21K Ohm resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) x 6.02mm (D) x 1.47mm (H). The isolated (ISOL) circuit design provides superior signal integrity, while the 100V maximum voltage rating and 0.75W total power dissipation make it suitable for high-reliability applications.

GQ8A022102BBT Features

• Precision Performance: 0.1% tolerance and ±50ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Construction: Ceramic substrate ensures thermal stability and durability in harsh environments.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C.
• Isolated Design: Independent resistors minimize crosstalk in multi-channel systems.
• Compact & Reliable: QSOP-16 package with 0.64mm pitch gull-wing leads for high-density PCB layouts.
• Non-Automotive: Ideal for industrial, medical, and test equipment where PPAP compliance is not required.

GQ8A022102BBT Applications

• Precision Instrumentation: DAC/ADC reference networks, bridge circuits, and sensor interfaces.
• Medical Electronics: Patient monitoring systems and diagnostic equipment requiring low drift.
• Industrial Controls: PLCs, motor drives, and power supply feedback loops.
• Communications: RF matching networks and signal attenuation in base stations.
• Test & Measurement: Calibration devices and high-accuracy voltage dividers.

Conclusion of GQ8A022102BBT

The GQ8A022102BBT excels in applications demanding high precision, thermal stability, and isolation. Its thin-film technology, ceramic construction, and gull-wing termination provide a superior alternative to standard thick-film networks, particularly in high-frequency or thermally variable environments. While not RoHS-compliant, it remains a top choice for legacy or specialized systems where performance outweighs regulatory constraints. Engineers will value its repeatable accuracy and robust packaging for critical designs.
