GQ0A031303DT Description

The GQ0A031303DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP device integrates 10 isolated resistors, each rated at 130KΩ with a tight tolerance of 0.5% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic package, it offers superior thermal stability and durability, making it ideal for harsh environments. With a 1W total power rating (0.1W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in precision circuits.

GQ0A031303DT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR for accurate signal processing.
• Robust Construction: Ceramic case and gull-wing termination ensure mechanical and thermal resilience.
• Isolated Design: ISOL circuit configuration prevents cross-talk, ideal for multi-channel systems.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density PCB layouts.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive (non-AECQ) applications.
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring specific material properties.
