GS4A034640FFT

GS4A034640FFT Description

The GS4A034640FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 4-resistor isolated network features a 464Ω resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in precision circuits. Encased in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination for reliable surface-mount assembly. The thin-film technology and ±25ppm/°C temperature coefficient provide excellent stability across a wide operating temperature range of -70°C to +125°C, making it suitable for harsh environments. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power handling and miniaturization.
