GQ8A039090CAT Description

The GQ8A039090CAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation applications. Encased in a ceramic QSOP package, it offers a 909Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a -70°C to +125°C operating range. Rated for 0.75W total power (0.1W per resistor) and 100V maximum voltage, this 16-pin gull-wing SMD component is ideal for precision analog and mixed-signal circuits. Its isolated (ISOL) circuit design minimizes crosstalk, while the ceramic substrate enhances thermal performance. Packaged in a tube, it suits automated assembly processes.

GQ8A039090CAT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic case and thin film technology ensure durability and low noise.
• Isolated Design: Independent resistors (ISOL configuration) prevent signal interference.
• Space-Efficient: Compact QSOP-16 footprint (4.9mm × 6.02mm × 1.47mm) with 0.64mm pitch.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade prototypes (non-PPAP).
• High Voltage Tolerance: 100V rating per resistor, ideal for signal conditioning and voltage division.

GQ8A039090CAT Applications

• Precision Instrumentation: Medical devices, test equipment, and sensor interfaces requiring minimal drift.
• Industrial Controls: PLCs, motor drives, and power management systems with isolation needs.
• Communications: RF modules and baseband signal processing where crosstalk mitigation is critical.
• Automotive Prototyping: Non-PPAP designs for infotainment or ADAS, leveraging its thermal resilience.

Conclusion of GQ8A039090CAT

The GQ8A039090CAT excels in applications demanding high accuracy, thermal stability, and electrical isolation. Its ceramic QSOP package and thin film technology provide superior performance over plastic-encased alternatives, while the ISOL configuration ensures signal integrity. Though non-RoHS and unconfirmed for mass production, it remains a top choice for prototyping and niche industrial designs requiring precision resistor networks.
