GQ0B0278R7GDT Description

The GQ0B0278R7GDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications in demanding electronic circuits. This 19-resistor BUS-configuration array delivers a 78.7Ω resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating range of -55°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) with gull-wing terminations for reliable PCB mounting. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines durability with precision, making it ideal for high-density analog/digital designs.

GQ0B0278R7GDT Features

• Advanced Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±50ppm/°C) for stable performance in thermal variations.
• Robust Ceramic Package: Enhances thermal management and mechanical strength, suitable for industrial environments.
• High-Density Integration: 19 resistors in a QSOP-20 form factor save board space versus discrete components.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm pitch enable efficient SMT processes.
• Wide Voltage/Power Handling: Supports 100V max and 1W total dissipation, outperforming similar networks in power efficiency.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation applications.

GQ0B0278R7GDT Applications

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits and sensor signal conditioning.
