3.3 mm Contact Pitch, Connectors for Internal Power Supplies
DF33 Series
■Features
1. 5 A maximum current
Single row connector can carry current of 5 A with #20 AWG
conductor. Please refer to Table #1 for current ratings for multi-
position connectors using other conductor sizes.
2. Complete Locking Function
Reliable interior lock protects mated connectors from accidental
disconnection.
3. Prevention of Incorrect Connections
To prevent incorrect connection when using multiple connectors
having the same Number of contacts, 3 product types having
different mating configurations are available.
4. Prevention of incorrect board placement
Built-in posts assure correct connector placement and orientation
on the board.
5. Supports encapsulation
Connectors can be encapsulated up to 10 mm without affecting
the performance.
6. Prevention of Short Circuits Between
Adjacent Contacts
Each Contact is completely surrounded by the insulator housing
electrically isolating it from adjacent contacts.
7. Increased Retention Force of Crimped
Contacts and confirmation of complete
contact insertion
Separate contact retainers are provided for applications where
extreme pull-out forces may be applied against the wire or when a
visual confirmation of the full contact insertion is required.

■Precautions
●Forcefully unmating the connectors will risk damaging them; therefore, when it is difficult to unmate a
connector, first gently press down on it, then release the lock to allow removal.
●When performing a potting process, pay attention to the surface tension of the resin and fill the resin
accordingly.
●Depending on the method by which wires have been routed within the equipment, tension may be exerted
on the wires and a load applied to the contacts. Use of a retainer is recommended because of this.
●When reusing crimp contacts, raise the lance.
●Depending on the manufacturing lot and the storage conditions that have been used, the shade of the
molded parts may change somewhat; however, this will not affect performance.
■Rating
The rated current listed in the catalog indicates the nominal current per contact. When all contacts will be
carrying current, use a current limited to about one third of the listed rating.
Note that even when the rated current of the connector body is 3 A, when the nominal current of the
specified wire is 1 A, the connector shall be used to handle 1 A overall.
Also, do not mate or unmate by hot plug. (See Note 1)
Note 1: The hot wire means that the wires are mated or unmated while electricity is being supplied to them.
■Application Environment
Please contact us when the application environment is such that the equipment will be used under
repetitively hot and cold temperatures.
