GS8A0138R3GDT Description

The GS8A0138R3GDT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin SOIC ceramic package, it offers 38.3Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.1W (1/10W) per resistor (0.8W total), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk, while the gull-wing termination facilitates robust surface-mount (SMD) assembly. With a 100V maximum voltage rating and thin-film technology, it delivers stable performance in precision circuits.
