SON-NS4ALF-03-1003-B Description

The SON-NS4ALF-03-1003-B from TT Electronics/IRC is a high-precision 4-resistor thin-film array in an 8-pin SON (Small Outline No-Lead) package, designed for demanding surface-mount applications. It features a 100KΩ resistance per resistor with an ultra-tight ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -55°C to +150°C. The 0.4W total power rating (0.1W per resistor) and 50V maximum voltage rating make it suitable for precision analog and signal conditioning circuits. Its convex termination style enhances solder joint reliability, while the compact 5.08mm × 3.81mm × 0.71mm footprint optimizes PCB space.
