GQ8A023921CBT Description

The GQ8A023921CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor array features a 3.92KΩ resistance value per resistor with an ultra-tight 0.25% 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 superior thermal stability and durability. The 16-pin gull-wing SMD configuration enables reliable surface-mount assembly, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs.

GQ8A023921CBT Features

• Precision Performance: 0.25% tolerance and ±50ppm/°C TCR for high-accuracy signal conditioning.
• Robust Construction: Ceramic case ensures excellent thermal dissipation and mechanical strength.
• Space-Efficient Design: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch for compact PCB layouts.
• High Voltage Handling: 100V maximum voltage rating for industrial and automotive-grade applications.
• Reliable Termination: Gull-wing leads provide secure soldering and vibration resistance.
• Non-Automotive (PPAP No): Ideal for industrial, medical, and instrumentation uses where EU RoHS compliance is not mandatory.

GQ8A023921CBT Applications

This resistor network excels in:

• Precision analog circuits (e.g., DAC/ADC reference dividers, sensor interfaces).
• Medical equipment requiring stable, low-drift resistance values.
• Industrial control systems with high thermal or voltage demands.
• Test & measurement instruments where accuracy and repeatability are critical.
• Telecom infrastructure (e.g., signal conditioning in RF modules).

Conclusion of GQ8A023921CBT

The GQ8A023921CBT stands out for its combination of precision, power handling, and compact form factor, making it a top choice for engineers prioritizing performance in harsh environments. Its ceramic construction and thin-film technology deliver superior reliability over plastic-encapsulated alternatives, while the QSOP package ensures compatibility with high-density designs. Though not RoHS-compliant, it remains a robust solution for non-automotive industrial applications demanding tight tolerances and thermal stability.
