GQ8A038452JGT Description

The GQ8A038452JGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance and thermal performance. Encased in a ceramic QSOP package, it offers 84.5K Ohm resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. The isolated (ISOL) circuit design allows independent resistor functionality, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust operation in compact layouts. Rated for 100V maximum voltage and 125°C maximum temperature, it is suited for demanding environments.

GQ8A038452JGT Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Ceramic QSOP package: Enhances thermal management and durability in high-temperature applications.
• Gull-wing termination: Ensures reliable surface-mount (SMD) compatibility with a 0.64mm terminal pitch for high-density PCB designs.
• Wide temperature range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-adjacent systems (though not PPAP/Automotive certified).
• Non-RoHS compliant: Suitable for legacy or specialized applications where RoHS exemptions apply.
• Precision tolerances: Tight ±0.1mm height/length and ±0.2mm depth tolerances ensure consistent mounting.

GQ8A038452JGT Applications

This resistor network excels in:

• Signal conditioning circuits: Isolation of analog/digital signals in data acquisition systems.
• Voltage dividers: Precision dividers in sensor interfaces or ADC reference circuits.
• Industrial control systems: Stable performance in PLCs, motor drives, and power supplies.
• Test & measurement equipment: Low-drift resistance for calibration and instrumentation.
• Aerospace/defense electronics: Ceramic packaging withstands harsh environments (note: verify compliance for critical use).
