GS4A032800BT Description

The GS4A032800BT from TT Electronics/IRC is a high-precision, 4-resistor isolated network housed in an 8-pin narrow SOIC ceramic package. Designed for demanding applications, it features a 280Ω resistance value with an ultra-tight ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
