GQ8B011021BT Description

The GQ8B011021BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 15-resistor BUS-configuration array offers a 1.02KΩ resistance per element with an exceptional ±0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic QSOP package, it features 16 gull-wing terminals for reliable surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably in temperatures ranging from 70°C to 125°C. The 4.9mm × 6.02mm × 1.47mm compact footprint (±0.1mm dimensional tolerance) makes it ideal for space-constrained designs.

GQ8B011021BT Features

• Precision Performance: Thin-film technology delivers 0.1% tolerance and ±100ppm/°C TCR for stable, high-accuracy signal conditioning.
• Robust Construction: Ceramic case ensures thermal stability and durability in harsh environments.
• High Power Handling: 0.75W total dissipation (0.05W per resistor) supports power-sensitive applications.
• Space-Efficient: QSOP-16 gull-wing package (0.64mm pitch) optimizes PCB real estate.
• Wide Operating Range: Functions from 70°C to 125°C with derated power, suitable for industrial and automotive (non-AEC-Q200) use.
• BUS Configuration: Simplifies circuit design in multi-channel systems like DACs/ADCs.

GQ8B011021BT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor calibration in test/measurement equipment.
• Signal Processing: DAC/ADC reference networks, gain-setting arrays in audio/communication systems.
• Industrial Controls: PLCs, motor drives, and power management where tight tolerance is critical.
• Medical Devices: Low-drift circuits for patient monitoring or diagnostic tools.
• Aerospace & Defense: Reliable performance in avionics or radar systems (note: non-RoHS).

Conclusion of GQ8B011021BT

The GQ8B011021BT excels in applications demanding precision, stability, and compactness. Its ceramic thin-film construction, BUS topology, and tight electrical specs make it superior to generic thick-film arrays, particularly in high-reliability or thermally challenging environments. While not automotive-qualified or RoHS-compliant, it remains a top choice for industrial, medical, and aerospace designs where accuracy outweighs regulatory constraints. Packaged in tubes for automated assembly, it balances performance with manufacturability.
