GQ0A033742JGT Description

The GQ0A033742JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature drift. This 20-pin QSOP package features 10 isolated resistors, each rated at 37.4kΩ ±5% tolerance, with a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding analog and digital circuits.

GQ0A033742JGT Features

• Precision Thin Film Technology: Delivers low noise and high stability, critical for sensitive signal conditioning.
• Isolated Resistor Design (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit configurations.
• High-Temperature Operation: Rated for 125°C maximum operating temperature, suitable for industrial and automotive environments (though not PPAP/automotive certified).
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances, optimizing PCB space.
• Gull-Wing Termination: Ensures reliable solder joint integrity for surface-mount applications.
• Non-RoHS Compliant: May be preferred for legacy systems requiring leaded components.
