ROHM 50years in Electronics

PMR Series chip resistors offer ultra-low resistance ranging from 1 mΩ to 10 mΩ while providing excellent temperature characteristics. The PMR Series contributes to more precise power control for enhanced energy efficiency.

MCR004 Series chip resistors provide dimensional accuracy of ±20 μm in a size 0402 (01005 inch) package measuring only 0.4 (L) x 0.2 (W) x 0.13 (T) mm. Made with a high-precision processing method incorporating ROHM’ s original semiconductor technology, the MCR004 Series provides high-quality printing and accurate processing despite its ultra-small size. This innovative product improves the handling and mounting reliability of packaging machines.

With their bottom electrode structure, TCTU Series capacitors provide high capacitance in a small, low-profile size 1005 (0402 inch) package. These capacitors are suitable for portable devices such as cellular phones and MP3 players.

TCTO Series capacitors incorporate a highly conductive polymer that remarkably reduces ESR. Their size 3216 (1206 inch) package boasts a profile of only 1.1 mm. What’s more, with their bottom electrode structure, the TCTO Series is available in capacitances of up to 100 μF, the highest in the industry.*

ESR Series resistors provide remarkably improved surge resistance thanks to their unique resistor structure that eliminates voltage concentration. Because the ESR Series provides a higher power rating than conventional equivalents, a compact ESR Series resistor can be used to replace a larger general-purpose resistor.

ROHM is the only source of size 1608 (0603 inch) EMI filters compatible with 4 A current.* These filters reduce internal resistance, resulting in reduced power loss. MCF18 Series filters are suitable for noise suppression in IC power lines and in imaging equipment.
