GQ0A0382R5DDT Description

The GQ0A0382R5DDT 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 82.5Ω resistance value and an ultra-tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±25ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) connectivity, while the 0.64mm terminal pitch accommodates high-density PCB designs. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision and reliability in critical circuits.

GQ0A0382R5DDT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal dissipation and long-term reliability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk, ideal for signal isolation.
• Compact Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) suit space-constrained applications.
• Surface-Mount Ready: Gull-wing terminals and QSOP package simplify automated assembly processes.
• Wide Voltage Range: Supports up to 100V, making it versatile for analog and digital systems.
