GQ8A035492CAT Description

The GQ8A035492CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 54.9KΩ resistance value with an ultra-tight ±0.25% 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 ceramic QSOP package, it offers superior thermal and mechanical stability, making it ideal for high-reliability environments. The isolated (ISOL) circuit design ensures minimal crosstalk between channels, while the 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads.

GQ8A035492CAT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.25%) and low TCR (±25ppm/°C) for stable performance.
• Ceramic QSOP Package: Enhances thermal conductivity and durability in harsh conditions.
• Isolated Resistor Network (ISOL): Minimizes interference between channels for clean signal integrity.
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C.
• Surface-Mount Gull Wing Termination: Ensures reliable PCB mounting with a 0.64mm pitch for compact designs.
• Robust Construction: 4.9mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth).
