GQ0A032550DT Description

The GQ0A032550DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 255 Ω resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit design. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±25 ppm/°C temperature coefficient for minimal drift across its -70°C to +125°C operating range. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, this network is ideal for precision analog and digital systems requiring reliable performance under varying environmental conditions.

GQ0A032550DT Features

• High Precision: 0.5% tolerance and ±25 ppm/°C TCR ensure stable performance in critical circuits.
• Robust Construction: Ceramic case and gull-wing termination provide mechanical strength and solderability.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel applications.
• Space-Efficient: Compact QSOP package (8.66 × 6.02 × 1.47 mm) with 0.64 mm pitch suits high-density PCB layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, derated for high-temperature environments.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
