GQ0A021053DAT

GQ0A021053DAT Description

The GQ0A021053DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 105K Ohm resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°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 a 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact designs.

GQ0A021053DAT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR for stable, repeatable performance.
• Robust Construction: Ceramic substrate and thin-film technology ensure durability and low noise.
• Compact Form Factor: 8.66mm x 6.02mm x 1.47mm dimensions with a 0.64mm terminal pitch, ideal for space-constrained PCBs.
• Isolated Resistors: 10 independent resistors (ISOL circuit designator) for flexible circuit design.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Surface-Mount Ready: Gull-wing terminals simplify automated assembly processes.
