GUS-QS8A-01-2490-GG Description

The GUS-QS8A-01-2490-GG from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. With a 249Ω resistance value per resistor and a tight 2% tolerance, this device ensures reliable signal conditioning and voltage division in compact circuits. Packaged in a 16-pin QSOP (Quarter Small Outline Package), it features gull-wing SMD termination for secure surface mounting. The network operates across a wide temperature range of -70°C to +125°C, with a derated power handling up to 125°C, making it suitable for demanding environments. Its ±100ppm/°C temperature coefficient guarantees stable performance under thermal stress.

GUS-QS8A-01-2490-GG Features

• Thin Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• High Power Handling: 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, ideal for power-sensitive designs.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Compact Footprint: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, saving PCB space.
• Robust Construction: 100V maximum voltage rating and 125°C max operating temperature ensure durability in harsh conditions.
• Tube Packaging: Protects components during handling and assembly.
