GQ0A021801JGT Description

The GQ0A021801JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 20-pin QSOP package features 10 isolated resistors, each with a 1.8KΩ resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability, making it ideal for harsh environments. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. Its gull-wing termination ensures secure surface-mount (SMD) attachment, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space efficiency.

GQ0A021801JGT Features

• Isolated Resistor Network: 10 independent 1.8KΩ resistors with 5% tolerance for precise signal conditioning.
• Thin-Film Technology: Delivers low noise, high stability, and tight TCR (±50ppm/°C).
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• High Power Handling: 1W total power (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 20-pin gull-wing SMD design (0.64mm pitch) for high-density PCB layouts.
• Wide Operating Range: Functions reliably from -55°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP-certified).

GQ0A021801JGT Applications
