GS8A028870JFT Description

The GS8A028870JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features an 887Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin SOIC ceramic package, it offers 0.1W power dissipation per resistor (0.8W total) and a 100V maximum voltage rating, making it suitable for demanding circuit designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.

GS8A028870JFT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and tight tolerance (±5%).
• Robust Construction: Ceramic SOIC package ensures durability and heat dissipation.
• Isolated Design: Circuit designator "ISOL" indicates individual resistor isolation, reducing crosstalk.
