GQ8B011581DAT Description

The GQ8B011581DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 1.58KΩ resistance value per element, offering a 0.5% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and durability, making it suitable for harsh environments. With a 0.75W (3/4W) total power rating and 0.05W per resistor, it balances power handling with compact surface-mount (SMD)

GQ8B011581DAT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• High-Density Integration: 15 resistors in a 16-pin QSOP (4.9mm × 6.02mm × 1.47mm) save PCB space.
• Wide Operating Range: -70°C to +125°C derated power range, with 100V maximum voltage rating.
• Reliable Termination: Gull-wing leads provide secure surface-mount (SMD) attachment.
• Automated Assembly Friendly: Tube packaging facilitates pick-and-place processes.

GQ8B011581DAT Applications

Ideal for precision analog and digital systems, including:

• Signal conditioning in industrial sensors and test equipment.
• Voltage division in automotive ECUs (where non-automotive compliance is acceptable).
• Impedance matching for high-frequency communication modules.
• Medical instrumentation requiring stable, low-drift resistance networks.
• Power management circuits in aerospace/defense subsystems (note EAR99 ECCN for export control).

Conclusion of GQ8B011581DAT

The GQ8B011581DAT excels in space-constrained, high-reliability designs due to its thin-film technology, ceramic encapsulation, and precision specs. While not RoHS-compliant and unconfirmed for automotive use, its 0.5% tolerance, ±100ppm/°C TCR, and 125°C rating make it a standout choice for industrial, medical, and telecom applications. Engineers prioritizing stability, power density, and repeatability will find this resistor network a robust solution.
