GUS-QS8A-03-2802-GA Description

The GUS-QS8A-03-2802-GA from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. This thin-film surface-mount resistor array offers a 28K Ohm resistance per element with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull wing terminations, it features a compact 4.9mm × 6.02mm × 1.47mm footprint, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and miniaturization. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit configurations.

GUS-QS8A-03-2802-GA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• High Power Density: 0.75W total dissipation in a compact QSOP package outperforms similar arrays in power-to-size ratio.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Isolated Resistors: Independent 28K Ohm elements enable versatile biasing, termination, or pull-up/down applications.
• Robust Construction: Gull wing terminations and ±0.1mm height tolerance ensure reliable solder joints in automated assembly.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
