GQCA026490JGT

GQCA026490JGT Description

The GQCA026490JGT 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 24-pin QSOP package features 12 isolated resistors, each with a 649Ω 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 style and gull-wing termination provide excellent mechanical durability and ease of surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for demanding circuits requiring isolation and consistent performance.

GQCA026490JGT Features

• High Precision: Thin-film technology ensures low noise and stable resistance (±50ppm/°C).
• Robust Construction: Ceramic substrate enhances thermal stability and mechanical strength.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in sensitive applications.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with tight tolerances (±0.1mm height/length).
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, its performance suits industrial and telecom applications.
