GQ8B012550DDT Description

The GQ8B012550DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 255 Ohm resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±100ppm/°C. Encased in a ceramic package, it ensures excellent thermal stability and durability. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a -70°C to +125°C temperature range. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating makes it suitable for high-voltage circuits.

GQ8B012550DDT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR ensure stable operation in precision analog/digital circuits.
• Robust Construction: Ceramic case and thin-film technology provide superior thermal management and long-term reliability.
• High-Density Integration: 15 resistors in a compact QSOP-16 package (4.9mm x 6.02mm x 1.47mm) save board space.
• Wide Operating Range: Functions from -70°C to +125°C, ideal for industrial and automotive environments (though not PPAP/automotive-certified).
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch simplify automated assembly.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GQ8B012550DDT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers, feedback networks in op-amps, and ADC/DAC interfaces.
• Industrial Controls: PLCs, sensor arrays, and power management systems requiring stable resistance values.
• Test & Measurement Equipment: Calibration circuits and reference networks where low drift is critical.
• Telecommunications: Filtering and impedance matching in RF/high-frequency PCBs.
• Legacy Electronics: Repair or replacement in non-RoHS-compliant systems.
