GQ0A0239R2DT

GQ0A0239R2DT Description

The GQ0A0239R2DT 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 39.2 Ω resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case construction enhances thermal stability, while the thin-film technology delivers low noise and excellent long-term reliability. With a power rating of 1W total (0.1W per resistor) and a ±50ppm/°C temperature coefficient, this network is optimized for precision analog and digital systems operating in 70°C to 125°C environments.

GQ0A0239R2DT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR for stable performance under thermal stress.
• Robust Construction: Ceramic case and gull-wing termination ensure durability in surface-mount (SMD) applications.
• Isolated Resistors: 10 independent resistors (ISOL designator) prevent crosstalk, ideal for multi-channel systems.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.
• Compact Footprint: 8.66mm x 6.02mm x 1.47mm dimensions with a 0.64mm terminal pitch, enabling high-density PCB layouts.
• Non-Automotive Grade: Compliant with EAR99 ECCN but not PPAP or RoHS, targeting specialized industrial markets.
