GS4A011580JCT Description

The GS4A011580JCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 158Ω and a ±5% absolute tolerance. Its ±100ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -70°C to +125°C, making it suitable for environments with significant thermal fluctuations. The SOIC-C series construction offers robust mechanical stability, with a compact footprint (4.9mm × 5.99mm × 1.45mm) and gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it delivers consistent performance in analog and mixed-signal circuits.
