GUS-QS8A-03-56R0-CC Description

The GUS-QS8A-03-56R0-CC from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing terminations, this isolated network offers a 56Ω resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a -55°C to +125°C range, derated up to 125°C. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and 100V maximum voltage rating make it ideal for space-constrained, high-voltage designs.

GUS-QS8A-03-56R0-CC Features

• Precision Performance: Thin film technology ensures low noise, high stability, and excellent TCR tracking between resistors.
• Robust Construction: QSOP package with gull wing leads provides mechanical durability and ease of automated assembly.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms similar networks in power density.
• Isolated Design: Circuit designator "ISOL" indicates independent resistors, enabling flexible circuit configurations.
• Strict Tolerances: ±0.1mm length/height tolerances and ±0.2mm depth tolerance ensure consistent PCB fit.
• Non-Automotive/Non-RoHS: Suitable for industrial and commercial applications where RoHS compliance isn’t mandatory.
