SOMC1403100RGRZ Description

The SOMC1403100RGRZ from Vishay is a high-performance 14-pin SOIC thick film resistor network designed for precision applications requiring isolated resistance configurations. This 7-resistor network features a 100Ω resistance value per resistor with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +150°C. Encased in a molded SOIC package, it offers a compact footprint (9.91mm × 7.62mm × 2.03mm) with gull-wing SMD termination for reliable surface-mount assembly. Rated for 1.125W total power dissipation (0.16W per resistor) and 50V maximum voltage, it is ideal for high-density PCB designs demanding durability and precision.
