What is the TE 2204581-1 Elcon Mini Header?
The TE Connectivity 2204581-1 is a 3-position header from the Elcon Mini series, carrying three male power blades in a single row. It is a press-fit, right-angle through-hole connector — the press-fit termination eliminates soldering, which makes it a clean fit for backplane assemblies or any build where you want to avoid the thermal stress and rework hassle of a wave-solder joint. The right-angle orientation puts the mating axis parallel to the board, saving vertical space in an enclosure and letting you route the cable harness along the board edge.
What are the key ratings and what do they mean for the build?
The contact finish is silver at 3.00 µin — silver is a good conductor for high-current power duty, but it tarnishes faster than gold and has a lower mating cycle life. This header is sized for a power interconnect where you mate it once or a few times in the field, not for a high-cycle blind-mate backplane. The housing is rated UL94 V-0, so it meets the flame-retardant requirement for equipment inside an enclosure. The operating range of -40°C to 105°C covers automotive underhood and outdoor industrial cabinet environments — the connector can sit in a hot engine bay or a cold telecom cabinet without derating concerns.
