GS4B011201DBT Description

The GS4B011201DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS array features a 1.2KΩ resistance value 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 SMD termination, it offers excellent thermal stability and mechanical durability. The device supports 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 compact dimensions (4.9mm x 5.99mm x 1.45mm) and surface-mount design facilitate high-density PCB layouts.

GS4B011201DBT Features

• High Precision: 0.5% tolerance and ±100ppm/°C TCR for reliable signal integrity.
• Robust Construction: Ceramic case and thin-film technology ensure long-term stability.
• Space-Efficient: SOIC-8 package with 1.27mm terminal pitch optimizes board space.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Low Power Dissipation: 0.05W per resistor minimizes thermal load.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its performance aligns with industrial standards.
