GQ8A034872JT Description

The GQ8A034872JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying conditions. This 8-resistor isolated network features a 48.7K Ohm resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range. Encased in a ceramic QSOP package, it offers excellent thermal stability and durability. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining reliability. The 16-pin gull-wing SMD termination ensures secure surface mounting, and its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
