GQ0A021820GT

GQ0A021820GT Description

The GQ0A021820GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and isolation. This 20-pin QSOP package integrates 10 isolated resistors, each with a 182Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal drift across the -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (1W total), this network balances compactness (8.66mm x 6.02mm x 1.47mm) with robustness.

GQ0A021820GT Features

• Isolated Resistor Network: 10 independent resistors in a single QSOP-20 package, ideal for signal isolation.
• Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±50ppm/°C) vs. thick-film alternatives.
• High-Temperature Stability: Operates up to 125°C with derated power, suited for industrial environments.
• Ceramic Substrate: Enhances thermal management and mechanical durability.
• Gull-Wing SMD Termination: Facilitates automated PCB assembly and strong solder joints.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.
