GUS-QS8B-02-68R1-JF Description

The GUS-QS8B-02-68R1-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 68.1Ω resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness. The thin-film technology delivers excellent stability, with a low ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. Its gull-wing termination ensures reliable solder joints, while the QSOP package (4.9mm x 6.02mm x 1.47mm) optimizes board space efficiency. Rated for 125°C maximum operating temperature, it suits industrial and automotive-grade designs (though not PPAP or Automotive certified).
