GS4A011800JCT Description

The GS4A011800JCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each rated at 180Ω with ±5% absolute tolerance and an exceptional ±0.25% ratio tolerance. Its ±100ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it suitable for environments with fluctuating temperatures. The SOIC package (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations enables reliable surface-mount assembly, while the ceramic case enhances durability and thermal performance. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, this network is ideal for signal conditioning, voltage division, and impedance matching in compact PCB designs.
