GS8A0390R9JT

GS8A0390R9JT Description

The GS8A0390R9JT 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 90.9Ω resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The isolated (ISOL) circuit design provides independent resistors, enhancing flexibility in circuit configurations. With a 0.1W power rating per resistor (0.8W total) and a 100V maximum voltage rating, this surface-mount device (SMD) is ideal for compact, high-reliability designs. Its gull-wing termination ensures secure PCB mounting, while the ceramic case delivers superior thermal and mechanical stability.
