GUS-QS8A-03-7870-JA Description

The GUS-QS8A-03-7870-JA from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision surface-mount applications. This thin-film resistor array offers a 787Ω resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it features gull-wing termination for reliable SMD assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding circuit isolation and signal conditioning tasks.

GUS-QS8A-03-7870-JA Features

• High-Density Isolation: 8 independent resistors in a 4.9mm × 6.02mm footprint, ideal for space-constrained designs.
• Thin-Film Technology: Delivers superior accuracy (±5%) and low TCR (±25ppm/°C) compared to thick-film alternatives.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) with derating up to 125°C.
• Automated Assembly-Friendly: Gull-wing leads with 0.64mm pitch ensure compatibility with high-speed pick-and-place systems.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and telecom applications.
• Non-Automotive (PPAP No): Optimized for commercial and industrial use where PPAP compliance is not required.
