GQCA031540JFT Description

The GQCA031540JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable performance across a wide temperature range. This 24-pin QSOP package features 12 isolated resistors, each with a 154 Ω resistance value and a 5% tolerance, ensuring consistent signal integrity in complex circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift under thermal stress. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), it operates within a 70°C to 125°C derated power range, making it suitable for demanding environments.

GQCA031540JFT Features

• Isolated Resistor Network: 12 independent resistors (154 Ω each) with 5% tolerance, ideal for signal isolation.
• High-Temperature Stability: ±25ppm/°C TCR and 125°C max operating temperature ensure reliability in thermal cycling.
• Robust Construction: Ceramic QSOP package with gull-wing leads for mechanical durability and solderability.
• Precision Thin-Film Technology: Delivers low noise and high accuracy for sensitive analog/digital circuits.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length) for space-constrained PCBs.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and telecom applications.
