GS4B019091DCT

GS4B019091DCT Description

The GS4B019091DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS array features a 9.09KΩ resistance per element with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD terminations, it offers excellent thermal stability and mechanical durability. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Non-compliant with EU RoHS, it is supplied in tube packaging for automated assembly processes.

GS4B019091DCT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±100ppm/°C) for stable performance.
• Robust Ceramic Construction: Enhances thermal management and reliability in harsh environments.
• Compact SOIC-8 Package: Space-saving 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch for high-density PCB layouts.
