GS4A031503GBT

GS4A031503GBT Description

The GS4A031503GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 150 kΩ resistance and a tight ±2% absolute tolerance. Its ±25 ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic construction enhances thermal and mechanical reliability. Rated for 0.1 W per resistor (0.4 W total) and 100 V maximum voltage, it is ideal for high-density circuits requiring precision and durability.
