GS4A021872CT Description

The GS4A021872CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 18.7 kΩ and an ultra-tight tolerance of ±0.25%. The network operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring stability in harsh environments. Its SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations (1.27mm pitch) facilitates surface-mount assembly, while the ceramic case enhances thermal and mechanical durability. Rated for 100V maximum voltage and 0.1W per resistor (0.4W total), it offers ±50ppm/°C temperature coefficient for minimal drift.

GS4A021872CT Features

• Precision Performance: ±0.25% tolerance and ±50ppm/°C TCR ensure accuracy in critical circuits.
