GUS-QS8A-02-4122-CA Description

The GUS-QS8A-02-4122-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 41.2KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its reliability in power-sensitive designs.

GUS-QS8A-02-4122-CA Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), saving PCB space in dense layouts.
• Gull Wing Termination: Ensures robust solder joints for surface-mount assembly.
• Derated Power Handling: Maintains performance up to 125°C with derating from 70°C.
• 0.64mm Terminal Pitch: Compatible with automated pick-and-place processes.
