GQ8A023900CT Description

The GQ8A023900CT from TT Electronics/IRC is a high-precision, surface-mount resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 390Ω resistance value per element with an exceptional 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Encased in a ceramic QSOP-16 package with gull-wing terminations, it offers superior thermal stability and mechanical durability. Rated for 0.1W per resistor (0.75W total), it supports 100V maximum voltage, making it suitable for high-reliability circuits. The thin-film technology provides excellent noise immunity and long-term stability, while the isolated (ISOL) circuit design minimizes crosstalk.

GQ8A023900CT Features

• Precision Thin Film: Delivers ±50ppm/°C TCR and 0.25% tolerance for accuracy-critical designs.
• Robust Construction: Ceramic QSOP-16 case ensures thermal and mechanical resilience.
• High Power Handling: 0.75W total (0.1W per resistor) with 100V rating.
• Isolated Design: Reduces interference in multi-channel systems.
• Surface-Mount Gull Wing: 0.64mm pitch for compact PCB layouts.
• Extended Temperature Range: Operates reliably from -70°C to +125°C.
