GQ0A011912DBT Description

The GQ0A011912DBT 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 19.1KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in circuit design. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees stable performance across a wide 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 precision analog and digital systems.

GQ0A011912DBT Features

• High Precision: 0.5% tolerance and thin-film technology for low noise and drift.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Isolated Design: 10 resistors with independent isolation (ISOL) for flexible circuit routing.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
