GS4A011910FT

GS4A011910FT Description

The GS4A011910FT 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 191Ω resistance and a tight ±1% tolerance. Built with a rectangular ceramic package, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient. Rated for 0.1W per resistor (0.4W total) and operating up to 125°C, it is ideal for environments requiring reliable performance under moderate power dissipation. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its 100V maximum voltage rating makes it suitable for low-to-medium voltage circuits.

GS4A011910FT Features

• Isolated Resistors: Four independent resistors (191Ω each) for flexible circuit design.
• High Precision: ±1% absolute tolerance and ±100ppm/°C thermal stability.
• Robust Construction: Ceramic SOIC package ensures durability and heat resistance.
• Wide Operating Range: Functions from 70°C to 125°C with derated power.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for easy PCB integration.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Non-Automotive: Not PPAP-capable, but suitable for industrial and commercial use.

GS4A011910FT Applications
