It uses the standard 0.100\" (2.54 mm) pitch on both the row and position spacing, making it footprint-compatible with the vast majority of 0.100\"-pitch IDC sockets and shrouded headers on the market. All 32 positions are loaded with square pins, through-hole solder termination, and a push-pull fastening interface. Rated 5 A per circuit at 110 V, with 30.0 µin (0.76 µm) gold or Gold, GXT™ plating on the mating surface. The gold thickness is substantial enough for repeated mating cycles and signal-level currents without risking contact-resistance drift. The housing is rated UL94 V-0. This is a board-to-board interconnect — the unshrouded pins mate with a receptacle that provides its own alignment and polarization. Typical use is as a general-purpose PCB header for signal or low-power distribution where the mating half is a crimp housing or IDC socket. ## What the Key Ratings Mean for Your Fit The 0.100\" (2.54 mm) pitch is the de facto standard for breadboard-compatible headers. It drives the board footprint — every 0.100\"-pitch IDC socket or shrouded header with matching position count will align. The 32 positions are fully loaded; there is no option to populate selectively, so the BOM circuit count must match exactly. The 5 A per circuit rating is typical for this pitch class. The limiting factor is the temperature rise of the housing at full load — derate above ambient if running all circuits near the maximum. The 30.0 µin gold on the mating side is a robust plating grade; it handles hundreds of mating cycles without exposing the base metal, unlike thin flash gold that wears through quickly. Unshrouded means the pins are exposed and the header provides no keying. The mating receptacle must supply its own polarization and alignment features. The overall contact length of 0.730\" (18.54 mm) includes a 0.430\" (10.92 mm) mating section and a 0.200\" (5.08 mm) solder post — the post length suits standard 0.062\" to 0.093\" PCBs.","metaTitle":"Amphenol FCI 79821-132HLF BERGSTIK II Header, 32 Pos","metaDescription":"Amphenol FCI 79821-132HLF BERGSTIK II unshrouded header, 32 positions, 2 rows, 0.100\" pitch, 5 A, 30.0 µin gold, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"79821-132HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"79821","Number of Positions":"32","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Length - Post":"0.200\\\" (5.08mm)","Current Rating (Amps)":"5A","Overall Contact Length":"0.730\\\" (18.54mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.430\\\" (10.92mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c8f0394c32e820c9621af8eb0b9440c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/79821-132HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 79821-132HLF?","answer":"The pitch is 0.100\" (2.54 mm) on both the position spacing and the row spacing, making it compatible with standard 0.100\"-pitch IDC sockets and shrouded headers."},{"question":"Is 79821-132HLF shrouded or unshrouded?","answer":"It is unshrouded — the pins are exposed with no housing wall around them.
