RASMID™ Resistors & Diodes

ROHM RASMID™ Resistors and Diodes are a group of ultra-compact components offering breakthrough miniaturization levels utilizing techniques. These resistors and diodes feature unprecedented miniaturization and superior dimensional accuracy ±10µm. The RASMID products include Zener diodes, Transient Voltage Suppressor (TVS) diodes, Schottky barrier diodes, and 03015-size chip resistors. The 0402 sizes (0.4mm x 0.2mm) diodes are ideal for high-density applications such as smartphones and portable devices. These diodes consume very little energy and are environmentally friendly.
