GS4B011822DCT Description

The GS4B011822DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 18.2K Ohm resistance per element with a tight 0.5% 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 SOIC-8 package with gull-wing terminations, it offers excellent thermal stability and mechanical durability. The device operates at a maximum voltage rating of 100V and delivers a total power rating of 0.4W (0.05W per resistor), making it suitable for precision analog and digital circuits. Its surface-mount design (SMD) and compact dimensions (4.9mm x 5.99mm x 1.45mm) facilitate high-density PCB layouts.

GS4B011822DCT Features

• High Precision: 0.5% tolerance and ±100ppm/°C TCR for reliable signal conditioning.
• Robust Construction: Ceramic substrate enhances thermal performance and longevity.
• Space-Efficient: SOIC-8 package with 1.27mm terminal pitch optimizes board space.
• Wide Operating Range: -55°C to +125°C (derated power up to 125°C).
• Low Power Dissipation: 0.05W per resistor (0.4W total) balances performance and energy efficiency.
