GQ0A021910DDT Description

The GQ0A021910DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 191Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The gull-wing termination enables reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB layouts.

GQ0A021910DDT Features

• Precision Performance: Thin-film technology delivers low noise and high stability, critical for analog and mixed-signal circuits.
• Robust Construction: Ceramic case ensures excellent heat dissipation and mechanical strength, ideal for harsh environments.
• High Power Handling: 1W total power rating (0.1W per resistor) supports applications requiring sustained load conditions.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk, making it suitable for multi-channel isolation.
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) optimize space-constrained designs.
• Wide Voltage Range: 100V maximum rating accommodates industrial and automotive-grade requirements (though not PPAP/AEC-Q200 certified).
