GQ8A029102JT

GQ8A029102JT Description

The GQ8A029102JT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and thermal reliability. Encased in a ceramic QSOP package, this 16-pin surface-mount device offers 91KΩ resistance per element with a 5% tolerance and ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide operating temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit isolation needs. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm × 6.02mm × 1.47mm).

GQ8A029102JT Features

• Thin Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Ceramic Case: Enhances thermal conductivity and mechanical durability in harsh environments.
• Gull Wing Termination: Facilitates reliable surface-mount assembly and automated PCB placement.
• High-Temperature Operation: Rated up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 certified).
• Precision Tolerance: ±50ppm/°C TCR and 5% resistance tolerance ensure minimal drift under thermal stress.
• Isolated Design: Each resistor operates independently, eliminating cross-talk in signal conditioning or divider circuits.
