GUS-QS8A-02-2550-DA Description

The GUS-QS8A-02-2550-DA is a high-precision 8-resistor thin-film network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package features 255Ω resistors with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating, it balances compact dimensions (4.9mm x 6.02mm x 1.47mm) with robust electrical characteristics. The isolated (ISOL) circuit design and gull-wing termination enhance reliability in high-density PCB layouts. Packaged in tubes for automated assembly, it meets industrial-grade requirements (non-automotive, non-PPAP).

GUS-QS8A-02-2550-DA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD design with 0.64mm pitch, ideal for miniaturized electronics.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• High Power Density: 0.75W total power dissipation in a tiny footprint, outperforming similar arrays.
• Isolated Resistors: Independent 255Ω resistors (8 circuits) prevent cross-talk in multi-channel systems.
• Strict Tolerance: ±0.5% resistance accuracy ensures consistent performance in precision applications.

GUS-QS8A-02-2550-DA Applications
