The unshrouded design exposes the tin-plated square pins (0.260\" mating length) for direct mating with MTA-100 IDC receptacles or crimp housings — common in board-to-cable/wire applications. Rated 250VAC and the current depends on the wire gauge used in the mating half; the UL94 V-0 thermoplastic housing handles -55°C to 105°C, suitable for general-purpose industrial and consumer electronics enclosures. ## Board layout and routing fit The 0.110\" post length (2.79mm) and tin-plated solder tails (150.0µin thickness) are designed for wave-solder through-hole assembly; the 0.100\" insulation height keeps the body low above the board.","metaTitle":"3-644457-3 TE Connectivity MTA-100 Header, 3 Pos, 2.54mm","metaDescription":"3-644457-3 TE Connectivity AMP Connectors MTA-100 pin header, 3 circuits, 0.100\" pitch, right-angle through-hole, unshrouded, tin contacts, UL94 V-0.","metaKeywords":null},"attributes":{"series":"MTA-100","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"-","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"644457","Insulation Material":"Thermoplastic","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.110\\\" (2.79mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.260\\\" (6.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"150.0µin (3.81µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","priceTiers":[{"qty":1,"price":"$0.38000","currency":"USD"},{"qty":10,"price":"$0.34400","currency":"USD"},{"qty":100,"price":"$0.28670","currency":"USD"},{"qty":500,"price":"$0.24372","currency":"USD"},{"qty":1000,"price":"$0.21362","currency":"USD"},{"qty":5000,"price":"$0.19068","currency":"USD"},{"qty":10000,"price":"$0.17744","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c6d677044909ef2e6cccd287eff89642.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644457-3/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and position count of 3-644457-3?","answer":"0.100\" (2.54mm) pitch, 3 positions, single row, all positions loaded."},{"question":"Is 3-644457-3 the same as other MTA-100 headers?","answer":"Yes, it belongs to the MTA-100 series — same 0.100\" pitch and tin-plated contacts.
