GQCB011781JT

GQCB011781JT Description

The GQCB011781JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 24-pin QSOP (Quarter Small Outline Package) device integrates 23 resistors with a 1.78KΩ resistance value (5% tolerance) in a compact ceramic case, offering excellent thermal stability and reliability. With a thin-film technology foundation, it delivers a low ±100ppm/°C temperature coefficient, ensuring minimal resistance drift across its operating range of -70°C to +125°C. The network supports a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly processes.

GQCB011781JT Features

• Precision Thin Film: Ensures stable performance with low TCR (±100ppm/°C) and tight tolerance (±5%).
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package optimize board space.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch simplify pick-and-place assembly.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance is not required.
