GQCA0291R0GT

GQCA0291R0GT Description

The GQCA0291R0GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature drift. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated 91Ω resistors with a tight 2% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. Encased in a ceramic package, it offers superior thermal stability and durability, making it suitable for demanding environments. With a 0.1W power rating per resistor (1W total) and 100V maximum voltage rating, this surface-mount network is ideal for compact, high-density PCB designs.

GQCA0291R0GT Features

• Precision Thin Film Technology: Delivers low noise, high accuracy (±2%), and excellent TCR (±50ppm/°C).
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Isolated Resistors (ISOL): Each of the 12 resistors is electrically isolated, enabling flexible circuit design.
• High-Density QSOP Package: Compact 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm pitch gull-wing leads for space-constrained applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• 100V Voltage Rating: Suitable for industrial and telecom applications requiring higher voltage tolerance.

GQCA0291R0GT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Industrial Control Systems: PLCs, sensor interfaces, and isolation circuits where stability is critical.
• Telecommunications: RF matching networks, filter designs, and impedance matching.
• Medical Electronics: Patient monitoring equipment requiring low drift and high reliability.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical modules like infotainment systems.
