GQ8A0145R3GT Description

The GQ8A0145R3GT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers a 45.3Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding circuits, while its 100V maximum voltage rating enhances reliability in high-voltage environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GQ8A0145R3GT Features

• Precision Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Ceramic QSOP Package: Provides excellent thermal performance and mechanical durability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Low TCR (±100ppm/°C): Minimizes resistance drift under thermal stress.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances for space-constrained designs.
