GQ0A023902DBT Description

The GQ0A023902DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 39KΩ resistance value and an exceptional ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A023902DBT Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal dissipation and mechanical strength.
• Isolated Design: Independent resistors (ISOL configuration) prevent crosstalk in multi-channel systems.
• Surface-Mount Compatibility: Gull-wing termination and 0.64mm pitch enable easy PCB integration.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
