GS4A021333GT

GS4A021333GT Description

The GS4A021333GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 133KΩ resistance and a tight ±2% tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic construction enhances thermal and mechanical durability. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (0.4W total), it is ideal for demanding circuits requiring isolation and reliability.

GS4A021333GT Features

• Isolated Resistor Network: Four independent resistors in a single SOIC package, eliminating crosstalk.
• High Precision: ±2% tolerance and ±50ppm/°C TCR for consistent performance in varying conditions.
• Robust Construction: Ceramic case ensures thermal stability and mechanical strength.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Surface-Mount Design: Gull-wing terminals and 1.27mm pitch for easy PCB integration.
• Low Power Dissipation: 0.1W per resistor (0.4W total) suits energy-sensitive designs.
