GS4A033000GFT Description

The GS4A033000GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC device features four isolated thin-film resistors, each rated at 300Ω with a ±2% absolute tolerance and ±1% ratio tolerance. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -55°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while the gull-wing termination facilitates easy surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network balances power handling and space efficiency.
