GQ0A011100DDT

GQ0A011100DDT Description

The GQ0A011100DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 110Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±100ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital systems.

GQQ0A011100DDT Features

• High Precision: 0.5% tolerance and thin-film technology for low noise and drift.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Isolated Design: 10 individually isolated resistors (ISOL circuit designator) reduce crosstalk in multi-channel applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• Compact & Reliable: QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances ensures consistent PCB fit.
• Industry-Standard Compliance: EAR99 ECCN and non-automotive (PPAP No) classification for broad industrial use.

GQ0A011100DDT Applications
