GQ8A014302CAT

GQ8A014302CAT Description

The GQ8A014302CAT 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 43K Ohm resistance value with an ultra-tight 0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package with 16 gull-wing terminals, it offers excellent thermal stability and mechanical durability. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability circuits. Its isolated (ISOL) circuit design ensures minimal crosstalk, ideal for precision analog and mixed-signal systems.

GQ8A014302CAT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.25%) and low TCR (±100ppm/°C) for stable operation.
• Robust Ceramic QSOP Package: Enhances thermal performance and mechanical strength in harsh environments.
• Isolated Resistor Network (ISOL): Minimizes interference between channels, critical for sensitive analog circuits.
