GQ0A021203GT

GQ0A021203GT Description

The GQ0A021203GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP package features 10 isolated resistors, each with a 120K Ohm resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for durability in compact designs.

GQQ0A021203GT Features

• Isolated Resistor Network: 10 independent resistors (120K Ohm each) with 2% tolerance for precision signal conditioning.
• Thin-Film Technology: Delivers superior stability, low noise, and ±50ppm/°C TCR, outperforming thick-film alternatives.
• Robust Construction: Ceramic substrate and gull-wing leads ensure mechanical strength and solderability in QSOP-20 packaging.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power, suitable for industrial environments.
• High Voltage Handling: Supports up to 100V, ideal for isolation and voltage-divider circuits.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm) for space-constrained PCBs.
