Product Summary
The pkf4622si is a dc/dc power module. The MacroDens3 -7 W PKF 4000 I series true component level on-board DC/DC power modules are intended as distributed power sources in decentralized -48 V and -60 V 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.
