GS4A021620DT

GS4A021620DT Description

The GS4A021620DT 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 162Ω resistance and an absolute tolerance of ±0.5%. The network operates over a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount (SMD) assembly. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), it is ideal for precision analog and digital circuits.
