Product Summary
The pkf4111si is a 3-7 W dc/dc power module. The MacroDens3–7W PKF 4000 I series true component level on-board DC/DC power modules are intended as distributed power sources in decentralized – 48V and –60V DC power systems. Utilization of thick film technology and a high degree of silicon integration has made it possible to achieve a MTBF of more than 4.9 million hour.
