GS4A021651FT Description

The GS4A021651FT 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 1.65 kΩ resistance and a tight ±1% tolerance. With a ±50 ppm/°C temperature coefficient, it 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) offers a compact footprint, making it suitable for space-constrained designs. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it combines reliability with high-density integration.
