GS4A0251R1GDT Description

The GS4A0251R1GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors with a resistance value of 51.1Ω and a tight absolute tolerance of ±2%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and ±0.5% ratio tolerance make it ideal for applications requiring stable and matched resistance values. The SOIC-C series construction provides robust mechanical and thermal performance, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) suit both industrial and consumer electronics.
