The 1A ceiling is typical for 1.27mm-pitch headers and limits the per-circuit current to stay within the housing temperature rise. ## Unshrouded Design and Mating Considerations The male pin contact length is 0.120\" (3.05mm) — this sets the mating depth with the corresponding receptacle. Confirm the receptacle's pin acceptance depth to ensure full engagement. The base product number is 20021121. Peer variants include the 12-position 20021121-00012C4LF and the 16-position 20021121-00016C4LF, both with identical pitch, plating, and ratings.

A shrouded header has a plastic wall that protects the pins and provides keying to prevent mis-mating. The unshrouded design saves board space but offers less mechanical protection and no polarisation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/20021121-00010C4LF","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/20021121-00010C4LF when reusing this data.
