GS4A021690FCT Description

The GS4A021690FCT 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 resistance value of 169Ω and a tight ±1% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -55°C to +125°C, with derated power handling up to 125°C. The SOIC package (4.9mm × 5.99mm × 1.45mm) offers a compact footprint, making it ideal for space-constrained designs. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power efficiency and reliability. The gull-wing termination ensures robust surface-mount compatibility.
