GQ8B0263R4GT Description

The GQ8B0263R4GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 63.4Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient ensures minimal resistance drift across a wide 70°C to 125°C derated power range.

GQ8B0263R4GT Features

• High Power Handling: Delivers 0.75W (3/4W) total power dissipation, with 0.05W (1/20W) per resistor, ideal for compact, high-density designs.
• Precision Thin Film Technology: Offers low noise and excellent stability compared to thick-film alternatives.
• Robust Construction: Ceramic case and gull-wing leads enhance mechanical and thermal resilience.
• BUS Circuit Design: Optimized for bus termination, voltage division, and pull-up/down applications.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• 100V Maximum Voltage Rating: Suitable for moderate-voltage applications.

GQ8B0263R4GT Applications

This resistor network excels in:

• Analog/Digital Signal Conditioning: Precision voltage dividers in ADCs/DACs.
• Bus Termination: Impedance matching for high-speed data lines (e.g., SPI, I²C).
• Industrial Electronics: Sensor interfaces, PLCs, and power management circuits.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems.
• Medical Devices: Where stable resistance values are critical (note: non-RoHS compliance may restrict use in EU markets).
