GQCA0143R2GT

GQCA0143R2GT Description

The GQCA0143R2GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 43.2Ω resistance value and a 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the thin-film technology delivers excellent temperature stability with a ±100ppm/°C coefficient. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates across a wide temperature range of -70°C to +125°C, making it suitable for industrial and instrumentation use.
