GQ0A0126R1DDT Description

The GQ0A0126R1DDT 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 integrates 10 isolated resistors, each with a 26.1Ω resistance and a tight ±0.5% tolerance, ensuring exceptional accuracy. Encased in a ceramic package, it offers superior thermal stability and reliability across a wide temperature range of 70°C to 125°C. With a ±100ppm/°C temperature coefficient, this network minimizes resistance drift under thermal stress, making it ideal for precision circuits. The gull-wing termination facilitates surface-mount (SMD) assembly, while the 0.64mm terminal pitch ensures compatibility with high-density PCB designs.

GQ0A0126R1DDT Features

• High Precision: 0.5% tolerance and ±100ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case enhances durability and heat dissipation, supporting 1W total power (0.1W per resistor).
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk, suitable for multi-channel systems.
• Surface-Mount Ready: QSOP package with gull-wing leads for automated PCB assembly.
• Wide Voltage Range: 100V maximum rating accommodates diverse circuit requirements.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP-certified, ideal for industrial/telecom use.
