GQCA034531JFT Description

The GQCA034531JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 24-pin QSOP package features 12 isolated resistors, each with a 4.53KΩ resistance at 5% tolerance and a ±25ppm/°C temperature coefficient. Encased in a ceramic housing, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) integration, while the 0.1W (1/10) power rating per resistor and 1W total power rating make it suitable for distributed power dissipation.

GQCA034531JFT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors minimize crosstalk in multi-channel designs.
• Robust Ceramic Case: Enhances thermal performance and mechanical strength in harsh environments.
• High Voltage Tolerance: Supports up to 100V, ideal for industrial and instrumentation applications.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) for space-constrained PCBs.
• Gull Wing Termination: Ensures secure SMD soldering and compatibility with automated assembly processes.
