GUS-QS8A-01-1801-JF Description

The GUS-QS8A-01-1801-JF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in demanding electronic circuits. Encased in a 16-pin QSOP package with gull wing terminations, this surface-mount device offers a 1.8KΩ resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for applications requiring signal isolation or individual resistor control. With a 0.75W (3/4W) total power rating (0.1W per resistor) and an operating temperature range of -70°C to +125°C, this network delivers reliable performance in harsh environments.

GUS-QS8A-01-1801-JF Features

• Thin Film Technology: Ensures low noise, high stability, and tight tolerance (±5%) for precision applications.
• Robust Power Handling: Supports 0.75W total power dissipation (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H), enabling high-density PCB layouts.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, enhancing flexibility in circuit design.
• Wide Voltage Rating: 100V maximum voltage ensures compatibility with industrial and automotive systems (though not PPAP/automotive-certified).
• Stable Thermal Performance: ±100ppm/°C TCR minimizes resistance drift across temperature fluctuations.
