Note: ①Use“F”suffix is for added aluminum baseplate and“H”suffix for heat sink mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ②Exceeding the maximum input voltage may cause permanent damage; ③In order to ensure the output stability, a minimum capacitive load must be connected to the output side of the product. | ||||||||
