GS4A029092CT Description

The GS4A029092CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this isolated 4-resistor array offers a 90.9 kΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±50 ppm/°C temperature coefficient. Built with thin-film technology, it ensures stability and reliability across a wide temperature range of -70°C to +125°C. The SOIC-C series features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, making it ideal for space-constrained PCB designs. With a 0.4W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and durability in precision circuits.
