GUS-QS8B-03-4120-G Description

The GUS-QS8B-03-4120-G is a high-precision thin-film resistor network from TT Electronics/IRC, designed for surface-mount applications requiring stable performance in compact form factors. This 16-pin QSOP package integrates 15 resistors with a 412Ω resistance value, offering a 2% tolerance and a ±25ppm/°C temperature coefficient for reliable operation across a -70°C to +125°C range. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it balances power handling with precision. The gull-wing termination ensures secure PCB mounting, while the QSOP case (4.9mm x 6.02mm x 1.47mm) optimizes space efficiency.

GUS-QS8B-03-4120-G Features

• Thin-Film Technology: Delivers superior stability, low noise, and tight tolerance (±2%) for precision circuits.
• High-Temperature Resilience: Operates reliably up to 125°C, with derated performance up to 125°C.
• Compact QSOP Package: Ideal for high-density PCB designs, with a 0.64mm terminal pitch and ±0.1mm height tolerance.
• Robust Power Handling: 0.75W total dissipation (0.05W per resistor) supports moderate-power applications.
• Non-Automotive, Non-PPAP: Suited for industrial and commercial (non-automotive) use.
• Non-RoHS Compliant: Note for applications exempt from RoHS restrictions.

GUS-QS8B-03-4120-G Applications

• Precision Analog Circuits: Voltage dividers, feedback networks in op-amps, and sensor interfaces.
