The MacroDens™ PKF 5000 I series are high reliability, tight 5-6 W DC/DC power modules, designed for use in decentralized 24, 48 and 60VDC power systems. This series uses thick film technology and high integration of silicon devices to achieve MTBF of more than 49 million hours. These DC/DC power modules employ a highly reliable over-molded design with a height of only 8 mm, making them ideal for IT&T and other demanding industrial applications.
The PKF 5000 series from Ericsson Microelectronics offers ultra‑low height (8 mm) DC/DC power modules designed for decentralized 24‑48‑60 V systems in IT, telecom, and industrial applications. Both through‑hole and surface‑mount versions are supplied in tubes, trays, or tape‑and‑reel packages and meet stringent EMI and safety standards.
Key features include an input voltage range of 18‑72 V, typical efficiency of 82 % at 5 V, isolation voltage of 1 500 V, and an MTBF exceeding 4.9 million hours. The modules provide up to 5 W of output power, are optimized for free‑convection cooling, and include detailed mechanical, thermal, and environmental specifications.
