GS4A021103DT

GS4A021103DT Description

The GS4A021103DT 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 110 kΩ resistance and an absolute tolerance of ±0.5%. The network operates within a wide temperature range of -70°C to +125°C, ensuring stability in harsh environments. With a power rating of 0.1W per resistor (0.4W total) and a low temperature coefficient of ±50 ppm/°C, it delivers consistent performance under varying thermal conditions. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, making it ideal for space-constrained designs.
