GQ8A021821FT Description

The GQ8A021821FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a 16-pin QSOP ceramic package, it offers a 1.82KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. The device features gull-wing SMD termination for reliable surface-mount assembly and is rated for 0.1W (1/10W) power dissipation per resistor (0.75W total), with a maximum voltage rating of 100V. Its ceramic construction enhances thermal stability and durability, making it suitable for harsh environments.

GQ8A021821FT Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±50ppm/°C) for critical analog circuits.
• Robust Ceramic Package: Provides excellent thermal conductivity and mechanical strength, outperforming plastic-encased alternatives.
• High-Density QSOP Format: Compact 4.9mm × 6.02mm × 1.47mm footprint saves PCB space while accommodating 8 isolated resistors.
• Gull-Wing Termination: Ensures reliable solder joints and compatibility with automated pick-and-place processes.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C, ideal for industrial and automotive-grade designs (though non-PPAP).
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring leaded components.
