GS4A031503FAT

GS4A031503FAT Description

The GS4A031503FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 150 kΩ resistance and a tight ±1% absolute tolerance. The device operates within a temperature range of 70°C to 125°C and offers a ±25 ppm/°C temperature coefficient, ensuring stable performance under thermal stress. With a 0.1W (1/10W) power rating per resistor and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The SOIC-C series construction provides excellent mechanical durability, while the gull-wing termination ensures secure surface-mount assembly.
