GQ8A034301CBT Description

The GQ8A034301CBT from TT Electronics/IRC is a high-precision, thin-film resistor network designed for demanding isolation circuit applications. This 8-resistor array features a 4.3KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its isolated (ISOL) circuit configuration enhances signal integrity in noise-sensitive systems.
