GQ0A0268R0DCT

GQ0A0268R0DCT Description

The GQ0A0268R0DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package integrates 10 isolated 68Ω resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.

GQ0A0268R0DCT Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR for reliable signal integrity.
• Robust Construction: Ceramic case enhances thermal and mechanical durability.
• Isolated Resistors: 10 independent 68Ω resistors (ISOL configuration) for flexible circuit design.
• Surface-Mount Ready: Gull-wing termination and QSOP package (8.66mm x 6.02mm x 1.47mm) ensure easy PCB integration.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Low Noise: Thin-film technology minimizes parasitic effects, critical for sensitive analog applications.

GQ0A0268R0DCT Applications
