GS8A0227R4FDT Description

The GS8A0227R4FDT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic SOIC-16 package, it offers 27.4Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for applications requiring individual signal paths. With a 0.1W power rating per resistor (0.8W total), 100V maximum voltage rating, and surface-mount gull wing termination, this network balances precision, power handling, and compactness.
