GS8A0138R3FFT

GS8A0138R3FFT Description

The GS8A0138R3FFT from TT Electronics/IRC is a high-performance 8-resistor isolated network in a 16-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Built with ceramic substrate and gull-wing terminations, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient and ±1% absolute tolerance. Each resistor is rated for 0.1W (1/10W), with a combined power handling of 0.8W, and operates reliably across a 70°C to 125°C derated temperature range (max 125°C). The 38.3Ω resistance value and 100V maximum voltage rating make it suitable for signal conditioning, voltage division, and isolation circuits in demanding environments.

GS8A0138R3FFT Features

• Isolated Resistor Network: Eight independent resistors (16-pin SOIC) for flexible circuit design.
• Precision Thin Film: ±1% tolerance and ±1% ratio tolerance ensure consistent performance.
• Robust Construction: Ceramic case with rectangular SOIC package (9.91mm x 5.99mm x 1.45mm) and ±0.1mm dimensional tolerances.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C) with ±100ppm/°C TCR.
• Surface-Mount Ready: Gull-wing terminations with 1.27mm pitch for automated PCB assembly.
• High Voltage Rating: Supports up to 100V, ideal for industrial and telecom applications.
