GS4A0142R2FFT

GS4A0142R2FFT Description

The GS4A0142R2FFT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications in demanding environments. Housed in a narrow SOIC-8 ceramic package, it features 42.2Ω thin-film resistors with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring exceptional accuracy. The device operates over a wide temperature range (-70°C to +125°C) with a ±100ppm/°C temperature coefficient, making it suitable for stable performance under thermal stress. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power handling and compactness. The gull-wing termination and 1.27mm pitch facilitate reliable surface-mount assembly.
