GQ8A031403GGT Description

The GQ8A031403GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor network features a 140K Ohm resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 16 gull-wing terminals for secure surface-mount (SMD) assembly, making it ideal for densely populated PCBs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm × 6.02mm × 1.47mm).

GQ8A031403GGT Features

• Precision Thin Film Technology: Delivers stable resistance with minimal drift.
• High Power Density: 0.1W per resistor (0.75W total) in a compact QSOP footprint.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
