GQ8A025101DBT Description

The GQ8A025101DBT from TT Electronics/IRC is a high-precision, surface-mount thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates eight isolated 5.1kΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating range of 70°C to 125°C. Encased in a robust ceramic package, it offers superior thermal stability and durability, making it suitable for harsh environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in precision circuits.

GQ8A025101DBT Features

• High Precision: Thin-film technology delivers ±0.5% tolerance and ±50ppm/°C TCR for minimal drift.
• Robust Construction: Ceramic case and gull-wing termination ensure mechanical strength and solderability.
• Isolated Design: Eight resistors with independent isolation (ISOL circuit designator) for flexible circuit integration.
• Compact & Reliable: QSOP-16 package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch, ideal for space-constrained PCBs.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power handling.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and automotive-grade applications (though not PPAP/AEC-Q200 certified).
