GS4A0227R0FCT Description

The GS4A0227R0FCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin Narrow SOIC device features four isolated thin-film resistors, each with a 27Ω resistance and an absolute tolerance of ±1%, ensuring consistent performance in demanding circuits. With a ±50ppm/°C temperature coefficient, it maintains stability across a wide operating range of -55°C to +125°C, derated up to 125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, ideal for space-constrained designs, while the gull-wing termination ensures reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (0.4W total), it balances efficiency with durability.
