GQCA022551GFT Description

The GQCA022551GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 2.55KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The device operates over a wide temperature range of 70°C to 125°C with a ±50ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Encased in a ceramic package, it offers excellent 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 engineered for robust operation in compact designs.

GQCA022551GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 12 resistors operates independently, ideal for multi-channel isolation.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
• Low TCR (±50ppm/°C): Minimizes resistance drift under temperature variations.
• Automated Assembly-Friendly: 0.64mm terminal pitch and gull-wing leads ensure compatibility with high-precision pick-and-place systems.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.
