GQ8A0251R1JT

GQ8A0251R1JT Description

The GQ8A0251R1JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-resistor isolated network features a 51.1Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). Encased in a ceramic QSOP package, it offers excellent thermal dissipation and mechanical durability. The 16-pin gull-wing SMD configuration facilitates easy surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power circuits.

GQ8A0251R1JT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and 5% tolerance for consistent performance.
• Robust Construction: Ceramic case enhances thermal stability and longevity in harsh environments.
• Compact Design: 4.9mm × 6.02mm × 1.47mm (L×D×H) footprint with ±0.1mm dimensional tolerances ensures compatibility with high-density PCB layouts.
• Isolated Circuit Design: Independent resistors (ISOL) minimize crosstalk, ideal for signal conditioning and voltage division.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive (non-AECQ) applications.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch simplify automated assembly.

GQ8A0251R1JT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring stable resistance.
• Industrial Controls: PLCs, motor drives, and power supplies where thermal resilience is critical.
• Test & Measurement Equipment: Calibration circuits and signal attenuation due to low TCR.
• Consumer Electronics: Audio amplifiers and display drivers benefiting from compact, high-density packaging.

Conclusion of GQ8A0251R1JT

The GQ8A0251R1JT combines thin-film accuracy, ceramic ruggedness, and isolated design to address demanding electronic applications.
