Requirement for Ethernet-Interface

There is an extremly large number of suppliers for RJ45 connectors (with and without integrated
Ethernet transformer), or single Ethernet transformers on the market, therefor it is not possible
for us to test all possibilities. If you consider that there are various qualities (SMD / THT, with /
without LED, vertical / horizontal, with / without EMC springs tab at the top / bottom, single / mul-
tiple times, etc.) with RJ45 connectors alone, it is probably understandable.
In General, RJ45 connectors and the external or built-in Ethernet transformer must meet the fol-
lowing properties:
Required parameters for RJ45 connector:
CAT5, shielded if possible
To enable a quick start in the selection of appropriate components, we have compiled a list of
order numbers of Würth Elektronik below, where we source our components. Of course, other
manufacturers are possible, so the following list is to be considered exemplary.
RJ45 jack without transformer
We mainly use: Order-No. 615 008 140 121
For more information:
We had bad experiences with SMT connectors in the past, because in the field they got demol-
ished every now and then due to mechanical loads.
