GQ0A0290R9JCT Description

The GQ0A0290R9JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 20-pin QSOP package integrates 10 isolated resistors, each with a 90.9Ω resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide excellent mechanical durability and ease of surface-mount assembly. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding circuits requiring isolation and consistent performance.

GQ0A0290R9JCT Features

• Precision Thin Film Technology: Delivers low noise and high stability, critical for analog and signal conditioning circuits.
• Isolated Resistor Design (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit configurations.
• Robust Construction: Ceramic substrate and gull-wing leads ensure reliability in harsh environments.
• Compact QSOP Package: Measures 8.66mm (L) x 6.02mm (D) x 1.47mm (H), optimizing board space in high-density designs.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress, enhancing long-term accuracy.
