3.3mm Pitch Small Size Connectors for Internal Power Source DF33C Series Positive Lock Completely enclosed locking system Protection from shorts circuits between adjacent contacts Fig.1 Features Keying for multiple use 1. 5 Amps capacity Standard type (Resin: White) When used with 20 AWG wire, this connector has a maximum capacity of 5A. (For rated current with other types of wires, please refer to the table on the next page) 2. Secure lock mechanism Outer locking mechanism prevents accidental unmating due to external shocks or drops. (Fig.1) 3. Incorrect mating prevention Two different housings, a standard and R type, are available R type (Resin: Black) to ensure mis-mating does not occur when using multiple DF33C connectors on the same design. (Fig.2) 4. Accurate board placement Guide posts are used to help with board placement and prevent incorrect mating to the PCB. 5. Supports resin sealing Accepts resin sealing up to 6.5mm without affecting the performance. * The image on the left show header (the board 6. Short circuit prevention dip side), the image on the right show the The housing protects each contact by enclosing them in a box socket (cabel side). which also makes each contact independent of each other. * This guide key position is indicated in position This design prevents short circuits between adjacent contacts. facing the mating surface of the header. 7. Excellent contact retention A retainer is available to increase contact/cable retention and to assure complete contact insertion. The retainer should Fig.2 also be used when any mechanical stress cold be applied to the cable. 8. Prevents solder cracking To avoid solder crack, a glass-filled resin is used in the header housing to decrease thermal shrinkage. 9. Easy mating operation A clear tactile click is delivered upon the completion of the mating process. This simplifies mating and increases work efficiency, especially when operating in a noisy environment. 10. Glow Wire compliance (Compliant with IEC 60695-2-11) In cases where the application will demand a high level of reliability, such as automotive, 1 2021.3y please contact a company representative for further information.DF33C Series3.3mm Pitch Small Size Connectors for Internal Power Source Product Specifications Rated No. of rows No. of Contacts 20 AWG 22 AWG Operating Temperature Range -35 to +85 (Note 2) Current 1 2 to 6 contacts 5A 5A Operating Humidity Range 40 to 80% (Note 3) Ratings (Note 1) 2 4 to 12 contacts 5A 4A Storage Temperature Range -10 to +60 (Note 4) Rated AC/DC 500V Storage Humidity Range 40 to 70% (Note 4) Voltage Items Speci cations Conditions 1.

Note 1 : This is the maximum current rating while all pins are powered or used as all power lines. If you split the current over multiple lines, please factor in your own safety margin. Please contact Hirose Electric for inquiries on the assignment of pins and on the currents that can be delivered. Note 2 : Includes temperature rise caused by current ow. Note 3 : The connector should be completely dry. (no condensation present) Note 4 : The term storage refers to the long-term storage condition of unused products before PCB mounting. The operating temperature and humidity ranges are applied while in a non-energized state, while in transport or after PCB mounting.
