The 2-row, center-strip contact layout packs 48 circuits into a narrow footprint, suited for high-density signal routing in compact electronics. ## Shielding and solder retention for signal integrity and assembly An integral shield around the contact area reduces radiated EMI between the two boards, which matters when the connector sits near RF or high-speed digital traces.","metaTitle":"DF40GB(3.0)-48DS-0.4V(51) – Hirose DF40 0.40mm Pitch","metaDescription":"DF40GB(3.0)-48DS-0.4V(51) – Hirose DF40 series board-to-board receptacle, 0.40mm pitch, 48 positions, 2 rows, 3mm mated stack height, shielded, gold contacts","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Board-to-Board Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.016\\\" (0.40mm)","Series":"DF40","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Shielded, Solder Retention","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Height Above Board":"0.114\\\" (2.90mm)","Base Product Number":"DF40G","Number of Positions":"48","Mated Stacking Heights":"3mm","Contact Finish Thickness":"2.00µin (0.051µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/aec32b0d4a5f742c03de5786d68c7607.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the stacking height of DF40GB(3.0)-48DS-0.4V(51)?","answer":"The mated stacking height is 3mm, measured from the top of the header's mounting surface to the bottom of the receptacle's mounting surface.
