Frequently asked questions from developers and buyers
MagJack or discrete magnetics?
A MagJack integrates the transformer into the RJ45 jack and saves space; discrete magnetics offer more layout flexibility. We advise by design.
Which PoE class do I need?
The PoE requirement (802.3af/at/bt) determines transformer and connector. We select to match the power class.
Which fuse is right?
Rated current, tripping characteristic and package drive the choice. We support safe dimensioning.
How do I choose a DC/DC module?
Input/output voltage, power, isolation and efficiency are decisive – we help dimension the power tree.
Do I get advice and samples?
Yes – our application engineers support selection and dimensioning. Request your project now
