GUS-QS8A-02-5230-GA Description

The GUS-QS8A-02-5230-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 523Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.1W power rating per resistor and a total power dissipation of 0.75W, it balances efficiency and reliability. The 100V maximum voltage rating and isolated circuit design (ISOL) enhance its suitability for signal conditioning, voltage division, and impedance matching.

GUS-QS8A-02-5230-GA Features
