GS4A0278R7JDT Description

The GS4A0278R7JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 78.7Ω and a ±5% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient, ensuring stability in demanding environments. Its 0.1W (1/10W) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-reliability circuits. The SOIC-C series construction provides excellent thermal and mechanical durability, while the gull-wing termination ensures reliable surface-mount assembly.
