GQ8A021103BT

GQ8A021103BT Description

The GQ8A021103BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 110K Ohm resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for high-reliability environments. The 0.75W (3/4W) total power rating (0.1W per resistor) and gull-wing termination enable robust performance in compact, surface-mount designs.

GQ8A021103BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50ppm/°C TCR for critical analog/digital systems.
• High-Density Ceramic QSOP Package: 4.9mm x 6.02mm footprint with 1.47mm profile, ideal for space-constrained PCBs.
• Isolated Resistor Network: Independent resistors (ISOL configuration) prevent crosstalk in multi-channel designs.
• Wide Temperature Range: Stable performance from 70°C to 125°C with derated power handling.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm pitch simplify pick-and-place processes.

GQ8A021103BT Applications

• Industrial Automation: Precision voltage dividers in PLCs and sensor interfaces.
• Medical Electronics: Signal isolation in patient monitoring equipment.
• Test & Measurement: Calibration circuits requiring low drift and high accuracy.
• Telecom Infrastructure: Line termination and impedance matching in high-speed data systems.
• Aerospace & Defense: Ruggedized electronics where temperature stability is critical.

Conclusion of GQ8A021103BT

The GQ8A021103BT excels in applications demanding high precision, isolation, and compactness. Its ceramic QSOP package, thin film technology, and ISOL design provide superior performance over plastic-encased networks, particularly in harsh environments. While not RoHS-compliant, it remains a top choice for legacy or specialized systems where reliability outweighs regulatory constraints. Engineers will value its low TCR, tight tolerance, and power-handling capabilities in mission-critical circuits.
