GQ0A011103CT Description

The GQ0A011103CT 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 110KΩ resistors with an ultra-tight tolerance of ±0.25% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across a wide temperature range of 70°C to 125°C. The ceramic case construction enhances thermal stability and durability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and mixed-signal circuits.

GQ0A011103CT Features

• High Precision: ±0.25% tolerance and ±100ppm/°C TCR for critical accuracy.
• Robust Construction: Ceramic case ensures thermal and mechanical resilience.
• Isolated Design: 10 independent resistors (ISOL circuit designator) for flexible routing.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Surface-Mount Ready: Gull-wing terminals for automated PCB assembly.
• Non-Automotive: Suitable for industrial, medical, and test equipment (PPAP not required).

GQ0A011103CT Applications
