GS4A0229R4JDT Description

The GS4A0229R4JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features thin-film technology with a 29.4Ω resistance value and a tight ±5% absolute tolerance (±0.5% ratio tolerance). Its ±50ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power handling and compactness. The gull-wing termination and surface-mount design facilitate easy PCB integration.
