2.54mm Pitch Bottom Entry Type Connector MDF7 Series ■Features Board to Board size Freely settable 1. Board to Board Size Freely Settable The board to board size can be set at infinite stages, according to the header pin through type structure and the diverse header variation. The board to board size can be set at infinite stages. 2. Integrity of Parts Mounted Surface The parts mounted surface on two boards aren't face each other, and can be oriented in the same direction. 3. Wide Variation Single-row product, double-row product, tin plated and gold plated products are lined up. In addition, the header to correspond to the board to board size are prepared. Concerning board to board size, other products can be provided, in addition to products in this catalog. Please contact HRS company as required. ■Applications Internal connection of telephone sets and OA/FA equipment, connection between IPM, IGBT and the board.

Note 2: A quantity for delivery is determined per pack (100 pcs.). If needed, please order the products per pack. Note 3: The MDF7 series 2-row plating specification is different from the single-row plating specification. No-specification indicates the gold plating, and (01) indicates the tin plating. Note 4: As for the products, which HRS No. is not indicated in the above table, we will correspond to samples, and mass-production according to your demand. Please contact HRS company, as required. BApplication Pattern and PCB mounting pattern ●When the double-row straight pin header is used BPrecautions 1. Recommended Soldering Condition ■Flow Condition by Automatic Soldering Unit Soldering temperature: 250±5ç, Soldering time: within 2 seconds ■Manual Soldering Condition Soldering iron temperature: 290±10ç, Soldering time: within 2 seconds 2. Board Masking If the automatic soldering unit is used, block the pin header through-hole on the receptacle mounted board with the masking tape, etc., and prevent the flux pervasion. In addition, if much flux is adhered so as to affect the contact, please be sure to clean the board. 3. Cleaning Condition Refer to Nylon Connector Use Hand book. 4. Cautions ■It is impossible to fix the board to the board by the connector only. Please take actions to fix the board without using the connector. ■If the board deformation could occur due to vibration, please use the gold plating. ■Don't use the connector as the top entry. A253
