GQCA014021GGT

GQCA014021GGT Description

The GQCA014021GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP package features 12 isolated resistors, each with a 4.02KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a power rating of 1W (0.1W per resistor) and a wide operating temperature range of 70°C to 125°C, this network is engineered for durability in industrial and commercial environments.

GQCA014021GGT Features

• High Precision: ±100ppm/°C temperature coefficient minimizes resistance drift, critical for analog signal conditioning and feedback circuits.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical strength, outperforming standard epoxy-based networks.
• Isolated Design: 12 independent resistors (ISOL circuit designator) allow flexible configuration without crosstalk, ideal for multi-channel systems.
• Surface-Mount Ready: QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch gull-wing leads ensures compatibility with automated PCB assembly.
• High Voltage Tolerance: 100V maximum rating supports applications requiring elevated voltage isolation.

GQCA014021GGT Applications

This resistor network excels in:

• Industrial Control Systems: Precision voltage dividers and sensor interfaces where thermal stability is critical.
• Medical Equipment: Signal isolation in diagnostic devices due to low noise and high reliability.
• Telecommunications: Impedance matching in RF modules and baseband processing circuits.
• Automotive Electronics (non-Automotive PPAP): Engine control units (ECUs) requiring robust performance under thermal cycling.
