GQCA012201GT

GQCA012201GT Description

The GQCA012201GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package integrates 12 isolated 2.2KΩ resistors with a 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case provides excellent thermal and mechanical stability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network is ideal for demanding analog and digital circuits. Packaged in a tube, it offers ease of handling for automated PCB assembly.

GQCA012201GT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2% tolerance) for sensitive signal conditioning.
• Isolated Resistors (ISOL): Each of the 12 resistors operates independently, eliminating crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical durability in harsh environments.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) save PCB space.
• High Voltage Handling: Supports up to 100V, making it suitable for power supply dividers and sensor interfaces.

GQCA012201GT Applications

• Analog Signal Processing: Precision voltage dividers, DAC/ADC reference networks.
• Industrial Control Systems: Isolated feedback loops, PLCs, and instrumentation amplifiers.
• Telecommunications: Impedance matching and termination in high-frequency circuits.
• Medical Electronics: Patient monitoring equipment where stability and isolation are critical.
• Test & Measurement: Calibration circuits and multi-channel data acquisition systems.
