GS4A011240GFT

GS4A011240GFT Description

The GS4A011240GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features 4 isolated thin-film resistors, each with a 124Ω resistance value and a tight ±2% absolute tolerance (±1% ratio tolerance). Its SOIC package (4.9mm × 5.99mm × 1.45mm) ensures compact surface-mount integration, while the gull-wing termination facilitates reliable PCB connections. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for demanding circuits.
