GUS-QS8A-01-54R9-JF Description

The GUS-QS8A-01-54R9-JF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount circuits. Encased in a 16-pin QSOP (Quarter Small Outline Package), this isolated resistor network features a 54.9Ω resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it balances power handling and compactness, making it ideal for densely populated PCBs. The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating enhances its suitability for industrial and automotive environments.

GUS-QS8A-01-54R9-JF Features

• Thin Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), optimizing board space.
• Isolated Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• High Power Density: 0.75W total dissipation in a miniature footprint, outperforming similar networks in power efficiency.
• RoHS Non-Compliant: Suitable for legacy or exempted applications requiring leaded components.
