GUS-QS8A-03-1873-CA Description

The GUS-QS8A-03-1873-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 187K Ohm resistance value and an ultra-tight 0.25% tolerance, this component ensures exceptional accuracy in signal conditioning, voltage division, and impedance matching circuits. Housed in a compact 16-pin QSOP package with gull wing terminals, it offers a 0.75W (3/4W) total power rating and operates reliably across a wide temperature range of -55°C to +125°C, derated to 70°C to 125°C. Its ±25ppm/°C temperature coefficient guarantees stable performance in thermally variable environments.

GUS-QS8A-03-1873-CA Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit design.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard arrays in power-dense layouts.
• Compact QSOP Package: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) footprint saves PCB space while supporting 0.64mm terminal pitch for fine-pitch soldering.
• Robust Construction: Withstands 100V maximum voltage and industrial temperature extremes (125°C max operating temp).
• Non-Automotive Grade: Ideal for industrial, medical, and instrumentation applications where PPAP compliance is not required.

GUS-QS8A-03-1873-CA Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage references, DAC/ADC interfaces, and feedback networks in test equipment.
• Signal Conditioning: Isolation and impedance matching in sensor interfaces (e.g., RTDs, strain gauges).
• Power Management: Current limiting and load sharing in DC-DC converters or power supplies.
• Medical Electronics: Patient monitoring systems requiring long-term stability and low drift.
• Industrial Controls: PLCs and automation systems where space efficiency and reliability are critical.
