GS4A034641JBT Description

The GS4A034641JBT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications in demanding environments. Encased in a ceramic SOIC package, it features thin-film technology with a resistance value of 4.64KΩ (±5% tolerance) and a low temperature coefficient of ±25ppm/°C, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 8-pin narrow SOIC (SOIC-C series) construction offers isolated elements, making it ideal for circuits requiring electrical separation. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this network balances compactness (4.9mm × 5.99mm × 1.45mm) with robustness. Its gull-wing termination ensures reliable surface-mount assembly, while the ceramic case enhances thermal and mechanical durability.
