The 20021221-00010C4LF is a shrouded header vertical surface-mount connector featuring a 2x5 pin configuration with 1.27mm pitch spacing. The housing is constructed from high-temperature thermoplastic material (UL94-V0 black) with copper alloy terminals, providing robust mechanical and electrical performance. The connector is rated to withstand exposure to 260°C peak temperature for 10 seconds in convection infrared or vapor phase reflow ovens, making it suitable for lead-free soldering processes. Key dimensions include a body length of 9.53mm (DIM X), width of 6.99mm (DIM Y), and height of 5.08mm (DIM Z), with a 1.27mm pin pitch. This connector is commonly used in embedded systems, industrial control boards, and consumer electronics requiring reliable interconnection with compact form factors and high-temperature tolerance.
