3.3 mm Contact Pitch, Connectors for Internal Power Supplies DF33 Series Complete Locking Completely Function enclosed locking system Protection from shorts circuits between adjacent Contacts Features Prevention of Incorrect Connections 1. 5 A maximum current Standar d Type (Color: natural) 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 R Type (Color: black) 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. *The photographs on the left show header (the board dip side), the photographs on the right show the socket (cable side). 6. Prevention of Short Circuits Between *The guide key position is indicated in position facing Adjacent Contacts the mating surface of the header. 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. 2010.9 1 DF33 Series 3.3 mm Contact Pitch, Connectors for Internal Power Supplies Product Specifications Number of rows Number of contacts AWG20 AWG22 Operating temperature range -35 to 85 (Note 1) Current 1 2 to 6 5A 5A rating Operating humidity range 40% to 80% Ratings 2 4 to 12 5A 4A Storage temperature range -10 to 60 (Note 2) Voltage AC/DC 500V rating Storage humidity range 40% to 70% (Note 2) Item Specification Condition 1.
