GQCA0268R0GT Description

The GQCA0268R0GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP (Quad Small Outline Package) device integrates 12 isolated 68Ω resistors with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable operation across a -70°C to +125°C range. Encased in a robust ceramic package, it offers superior thermal stability and durability, making it ideal for harsh environments. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network balances compactness (8.66mm × 6.02mm × 1.47mm) with reliability. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the isolated (ISOL) circuit design minimizes crosstalk.

GQCA0268R0GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±50ppm/°C) for signal conditioning.
• Ceramic Case: Enhances thermal dissipation and mechanical strength vs. polymer-based alternatives.
• Isolated Resistors: 12 independent 68Ω resistors prevent interference in multi-channel systems.
