It carries tin-plated square male pins rated 3 A at 250 V, mounts through-hole with solder termination, and is housed in a UL94 V-0 rated glass-filled nylon 6/6 insulator. ## Shrouded housing and mated stack height The shrouded 4-wall header mates with the matching PUD crimp receptacle; the latch holder locks the pair together. Mated stacking height is 11 mm, with an insulation height of 0.378\" (9.60 mm) on the header side.","metaTitle":"JST PUD B20B-PUDSS-1(LF)(SN) Header, 20-Pos 2.00mm","metaDescription":"JST PUD header B20B-PUDSS-1(LF)(SN): 20 positions, dual row, 2.00 mm pitch, 3 A, 250 V, tin-plated contacts, through-hole solder termination.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"PUD","Package":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.079\\\" (2.00mm)","Product Status":"Active","Voltage Rating":"250V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.378\\\" (9.60mm)","Ingress Protection":"-","Base Product Number":"B20B-PUD","Insulation Material":"Polyamide (PA66), Nylon 6/6, Glass Filled","Number of Positions":"20","Row Spacing - Mating":"0.079\\\" (2.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.122\\\" (3.10mm)","Current Rating (Amps)":"3A","Operating Temperature":"-25°C~85°C","Mated Stacking Heights":"11mm","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3213681793cf3b3b8391ef0ed4389b89.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating style and keying of this header?","answer":"The header is shrouded on four walls and uses a latch holder for fastening.
