The press-fit termination eliminates the need for soldering, which is preferred in high-reliability backplane assemblies where rework and field replacement of individual connectors must be possible without desoldering. The single-row layout with 4 power contacts delivers a compact power interconnect for a 250V rated bus. ## Press-Fit Termination for Solderless Backplane Assembly The press-fit termination is the defining feature of this receptacle for a backplane architect. Instead of solder joints, the compliant press-fit tail deforms elastically into the plated through-hole, creating a gas-tight connection. This makes the 120953-1 well-suited for backplanes that undergo multiple rework cycles or operate in high-vibration environments where solder fatigue is a risk. The through-hole mounting provides mechanical retention through the board, and the press-fit interface meets the reliability requirements of telecom and datacom equipment where backplane connectors are rarely depopulated once assembled. ## Rated for 250V with Wide Temperature Range The 250V voltage rating is the headline electrical spec for this blade power receptacle. It is sized for power distribution within an enclosure — think a server chassis or industrial controller backplane — where the bus voltage stays under 250V.","metaTitle":"TE 120953-1 UPM Receptacle, 4-Position Blade Power","metaDescription":"TE Connectivity 120953-1 UPM receptacle, 4-position blade power, press-fit termination, 250V, UL94 V-0, -55°C to 125°C.
