GQCA031820GFT Description

The GQCA031820GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 182Ω (±2%) and a low temperature coefficient of ±25ppm/°C, ensuring minimal drift across its operating range of -70°C to +125°C. Encased in a robust ceramic package, it offers superior thermal management and durability in demanding environments. With a 0.1W (1/10W) power rating per resistor and a 100V maximum voltage rating, this network is ideal for analog signal conditioning, voltage division, and isolation circuits.

GQCA031820GFT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±25ppm/°C) for stable performance.
• Isolated Resistor Network (ISOL): 12 independent resistors prevent crosstalk, suitable for critical isolation applications.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Surface-Mount Gull Wing Terminals: Facilitates reliable PCB mounting with a 0.64mm pitch for high-density layouts.
• Wide Temperature Range: Operates from -70°C to +125°C, derated for power above 70°C.
• 1W Total Power Handling: Distributed across 12 resistors, enabling robust performance in compact designs.
