Small mated height and board occupied space Small pitch (0.3mm) and mated height (1.5mm) allows use in space-restricted areas. Plug’s height of 1.3mm and width of 2.38mm allow its passage through narrow openings in small-diameter hinge applications. 2. Enhanced shielding and ground connections Metal shells on the plug and receptacle connect to each other with a reliable multi-point ground contacts, assuring reliable ground connection and EMC protection. 3. Reliable lock Fully mated condition is assured with reliable locks at 4 locations, confirming it with a distinct tactile click. 4. Reliable electrical and mechanical connection Despite its small mated height, unique contact configuration assures highly reliable connection, with effective mating length of 0.4mm. Multi-point ground contacts 4-point lock: 2 points at each end 5. Solder wicking prevention Nickel barriers prevent solder wicking in the critical contact areas. 6. Durable plug construction Formed metal shells on the top and side surfaces form a strong and rigid assembly. ■Connector for conductivity tests We have a line-up of connectors for inspection, usable for electrical testing of both plug and receptacle connectors.

Recommended temperature profile Temperature (ç) 250 250ç 220ç 200 60sec. 180ç max. 150 150ç 90 to 120sec. 100 50 Room temperature 50 100 150 200 250 300 Time (sec.) Solder composition: Paste, 96.5%Sn/3.0%Ag/0.5%Cu Note 1: Up to 2 cycles of Reflow soldering are possible under the same conditions, provided that there is a return to normal temperature between the first and second cycle. Note 2: The temperature profile indicates the board surface temperature at the point of contacts with the connector terminals. 2.Recommended manual soldering Manual soldering: 350ç for 3 seconds Do NOT use flux compound when manual soldering. 3.Recommended screen thickness and open area ratio (Pattern area ratio) Thickness: 0.1 mm Open area ratio: Lead terminal: 80% Ground terminal: 100% 4.Board warpage Maximum of 0.02mm at the connector center, with both ends of the connector as reference points. 5.Cleaning conditions 6.Precautions Refer to “Nylon Connector Use Handbook”. * Mating and un-mating of the connectors when not soldered on the boards is not recommended as this may cause deformation of the terminals, damage to the contacts or insulators. * When mating/un-mating do not twist or lift by the corners. Apply the forces evenly across the entire length and width of the connectors taking care NOT to damage or deform soldered terminations. * Slight discoloration on the insulating materials will not affect form, fit or function of the connectors. 9 The product information in this catalog is for reference only. Please request the Engineering Drawing for the most current and accurate design information. DF38 Series●0.3 mm Pitch, 1.5 mm Mated Height, Board- to-Fine Coaxial Cable Connectors ■Precautions Precautions ■Mating Mate the plug with the receptacle by pressing straight against the entire plug surface. Do NOT un-mate the plug while holding by the terminated cable. Plug Lock areas Lock areas Receptacle ■Un-mating Use a dedicated extraction tool to un-mate the plug. Insert the tool under either end of the plug (clearance) and pull straight up as illustrated. Do NOT un-mate the plug while holding by the terminated cable. Extraction tool End side (clearance) ■Routing of the fine coaxial cable after termination Allow sufficient clearance between the plug and the fine coaxial cable to avoid sharp bend, excessive twist or pull forces applied to the connector. No pulling ■Other · Do NOT mate / un-mate the connectors when receptacle is not mounted on the board. · Different production lots may exhibit different shades of the insulator materials. No affect on form, fit or function of the connectors. · Rework of the soldered terminations on the board-mounted receptacles is not possible. · Sides of the metal cover protrude over the termination areas. · Do not mate / un-mate the connectors when receptacle is not mounted on the board. 10
