GS4B021001BT

GS4B021001BT Description

The GS4B021001BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (Small Outline Integrated Circuit) device features 7 bussed resistors with a 1KΩ resistance value and an exceptional ±0.1% absolute tolerance, ensuring reliable performance in precision circuits. Built with thin-film technology, it offers a low ±50ppm/°C temperature coefficient, maintaining stability across a wide operating temperature range of -70°C to +125°C. The SOIC-C series package provides robust mechanical durability, with a compact footprint (4.9mm length × 5.99mm depth × 1.45mm height) and gull-wing termination for secure surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for high-density PCB designs requiring consistent signal integrity.
