GS4A034870GFT Description

The GS4A034870GFT 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 487Ω resistance value and a tight ±2% absolute tolerance (with ±1% ratio tolerance). Built with ceramic substrate technology, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating range of -55°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) provides robust mechanical integrity, while the gull-wing termination ensures compatibility with surface-mount assembly processes. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for high-density PCB designs requiring precision resistance matching.
