SM Series Surface mountable DC-DC converters 78 Surface Mount Low Profile No Heatsink Required 10ms Start-up Remote on/off Belicore Compliance Worldwide Safety Agency Approvals Overvoltage Protection 24V or 48V Nominal Inputs Lambdas new SM Series is the first family of surface mount DC-DC converters that is designed specifically for card level distributed power applications targeted at the Telecom and Computer markets. Using 100% SMT technology in combination with our patented thermal management strategy, the SM Series offers a non-encapsulated solution reducing the weight restrictions required for pick and place operation with existing vacuum end effectors. The SM Series is available in 56 models at power ranges from 5 to 30 waits with standard input and output voltage ranges.
