GQ0A038871DT Description

The GQ0A038871DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 8.87KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in circuit design. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±25ppm/°C temperature coefficient, this network maintains stable performance across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) further enhance its suitability for precision analog and digital systems.

GQ0A038871DT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic substrate and gull-wing leads offer durability and excellent solderability.
• Isolated Design: 10 independent resistors (ISOL circuit designation) prevent crosstalk in sensitive applications.
• Wide Operating Range: Functions reliably from -70°C to +125°C, ideal for industrial and automotive-grade systems (though not PPAP/automotive certified).
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) save PCB space.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
