GQ8B021690FBT Description

The GQ8B021690FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 169 Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable solderability, while the thin-film technology delivers excellent thermal stability with a low ±50 ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range, making it suitable for harsh environments.

GQ8B021690FBT Features

• High Density Integration: 15 resistors in a compact 4.9mm x 6.02mm x 1.47mm QSOP package, ideal for space-constrained designs.
• Precision Performance: 1% tolerance and ±50 ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Automated Assembly Ready: Gull-wing leads and 0.64mm terminal pitch simplify high-volume SMT processes.
• Wide Operating Range: Derated power capability up to 125°C for industrial and automotive-adjacent uses (though not PPAP-certified).
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
