GS8B031241FFT

GS8B031241FFT Description

The GS8B031241FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. Housed in a 16-pin narrow SOIC package, this bussed (BUS) network integrates 15 thin-film resistors, each with a resistance value of 1.24KΩ and a tight ±1% absolute tolerance. The device operates within a temperature range of 70°C to 125°C (derated) and features a low ±25ppm/°C temperature coefficient, ensuring minimal resistance drift. With a maximum voltage rating of 100V and a power rating of 0.8W (0.05W per resistor), it is engineered for reliability in precision circuits. The SOIC-C series construction offers robust surface-mount compatibility, with gull-wing terminals and a compact footprint (9.91mm x 5.99mm x 1.45mm).
