GQ0A031690CCT

GQ0A031690CCT Description

The GQ0A031690CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a resistance value of 169Ω and an ultra-tight tolerance of ±0.25%. Encased in a robust ceramic package, it offers superior thermal stability and mechanical durability. The network operates over a wide temperature range of -70°C to +125°C, with a derated power handling capability up to 125°C. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift, making it ideal for precision analog and digital circuits.

GQ0A031690CCT Features

• High Precision: Thin-film technology delivers ±0.25% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case and gull-wing termination provide excellent thermal dissipation and solder joint reliability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk, suitable for multi-channel systems.
• Power Handling: 1W total power rating (0.1W per resistor) and 100V maximum voltage rating support high-density designs.
• Surface-Mount Compatibility: QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch enables compact PCB layouts.
• Wide Operating Range: Performs reliably from -70°C to +125°C, even under derated power conditions.
