GS8A011212CAT

GS8A011212CAT Description

The GS8A011212CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 12.1KΩ resistance per element with an ultra-tight ±0.25% absolute tolerance and ±0.05% ratio tolerance, this ceramic-based thin-film network ensures exceptional stability and accuracy. Its isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision voltage division or signal conditioning. With a ±100ppm/°C temperature coefficient and a 0.1W power rating per resistor, it delivers reliable performance across a -70°C to +125°C operating range. The SOIC package (9.91mm x 5.99mm x 1.45mm) offers compactness while maintaining robust 100V maximum voltage rating and gull-wing termination for secure PCB mounting.
