GS4A021473GFT Description

The GS4A021473GFT 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 resistance value of 147KΩ and a tight ±2% absolute tolerance. The network operates within a temperature range of 70°C to 125°C, delivering a power rating of 0.1W per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures stable performance under thermal variations, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits. Encased in a rectangular ceramic SOIC package, it offers robust mechanical stability and excellent thermal dissipation.

GS4A021473GFT Features

• Isolated Resistors: Four independent resistors (isolated design) for flexible circuit integration.
• Precision Tolerance: ±2% absolute tolerance (±1% ratio tolerance) for high-accuracy applications.
• Stable Performance: Low ±50ppm/°C TCR minimizes resistance drift across temperature fluctuations.
• Robust Construction: Ceramic case enhances durability and heat dissipation.
• Surface-Mount Design: Gull-wing termination and 1.27mm pitch for easy PCB assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
