Vishay Intertechnology, Inc. (NYSE: VSH) today announced it has launched the availability of a new series of thick film surface mount roll resistors, RCWH, which has a power rating of 0.33W and an external dimension of 0805. The power density of the Vishay Dale RCWH series resistors is more than 2.5 times the standard resistance of the same occupying space, saving space in communication, computer, industrial and consumer applications and reducing the number of components.

Today's these resistors have high power density and can replace larger designs or larger designs of larger-sized high-power devices or multiple lower-power resistors in new designs. This reduces the required board space and assembly costs while achieving smaller, lighter end products. In addition, RCWH series resistance reduces the thermal expansion coefficient difference (CTE) with the PCB board, which can reduce the stress of the solder joint, it can achieve greater reliability than the larger thickness of the thick film resistors.You also buy them on omoelec.com website.

RCWH resistance of 0.01Ω ~ 0.976Ω, tolerance of ± 0.5%, TCR as low as ± 100ppm / ℃. Resistors are RoHS compliant, halogen-free, coated with protective metallic glaze on high quality ceramic. Resistors are suitable for DC / DC converters, regulators, and current-sense resistors and shunts for inverters in mobile phones, computers, air conditioners and heat pumps.

RCWH now offers samples and has been in volume production, with lead times of six weeks to eight weeks.
