GQ0A0143R0JT

GQ0A0143R0JT Description

The GQ0A0143R0JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision isolation applications. This 20-pin QSOP (Quarter-Small Outline Package) device integrates 10 isolated resistors, each with a 43Ω resistance value, 5% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a robust ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for reliability in high-temperature circuits. Its gull-wing termination ensures secure surface-mount (SMD) attachment, while the 100V maximum voltage rating accommodates moderate-voltage applications.
