GQCB016342GT Description

The GQCB016342GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 63.4KΩ resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GQCB016342GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Robust Construction: Ceramic substrate ensures excellent heat dissipation and reliability in harsh environments.
• Wide Operating Range: Derated power capability up to 125°C, suited for industrial and automotive (non-AECQ) applications.
• Consistent Performance: Tight resistance tolerance (±2%) and low TCR (±100ppm/°C) minimize drift over temperature.
• Efficient Power Handling: 1W total dissipation (distributed across resistors) supports moderate-power bus applications.
