GS4A033900BT

GS4A033900BT Description

The GS4A033900BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 390Ω resistance and an ultra-tight ±0.1% tolerance. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient (±25ppm/°C), ensuring stable performance in fluctuating thermal conditions. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly.
