GS4A012800BBT Description

The GS4A012800BBT 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 device features four isolated thin-film resistors, each with a resistance value of 280Ω and an absolute tolerance of ±0.1%. The network operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in harsh environments. Its ±100ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.
