GQ0A034992BBT Description

The GQ0A034992BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 49.9KΩ resistance value and an ultra-tight 0.1% tolerance. The ceramic case ensures excellent thermal stability, while the ±25ppm/°C temperature coefficient guarantees minimal drift across its 70°C to 125°C operating range. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it delivers reliable performance in precision analog and signal conditioning circuits.

GQ0A034992BBT Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case and gull-wing termination ensure durability and ease of soldering.
