Vitrohm Resistors

VITROHM was founded in 1933 and became a part of the Yageo Group in 1996. VITROHM manufactures resistors with a wide range of applications, such as wire wound, SMD,  Low OHM, Meta Glaze, and high-power wire wound resistors. VITROHM currently has approximately 200 employees with production sites in China and Portugal.

From Coated to Molded or Insulated

For low-to-medium rated power (1W…8W), VITROHM offers wirewound resistors. These resistors are coated with a special silicone-varnish that continuously withstand temperatures of 350°C. Series CRF is designed for safety applications, connected to mains-voltage.

For medium-to-high rated power (4W…40W), resistors are mounted in a ceramic case, which also provide full electrical insulation. Series KT and KF additionally provide a thermofuse, which interrupts a circuit in the event of electrical overload. Axial, radial and vertical styles are available.

Wirewound Resistors, Molded, Insulated

Series BW and BWF, wound on fibreglass core and capped in a special process, suit all requirements for automatic insertion due to moulded case. The accurate fusing characteristic of series BWF reliably protects circuits from electrical overload.

SMD and Low-Ohm Resistors

VITROHM also offers power SMD-resistors with metal band, wirewound, and film technology for current sense purposes, power, and precision applications. Series RWF and RWS for circuit-protection are also available. Rectangular size 5020 for automatic placement.

For many electronic applications (switch controllers, switch-mode power-supplies, frequency converters) induction-free resistors featuring very low ohmic values are needed. VITROHM offers a resistance range from 0R0005 to 3R3 and power ratings from 1W to 10W in several styles.
