The assembler relies on the pin-1 indicator and visual alignment. ## Housing and Compliance — UL94 V-0, Active Lifecycle The insulator is black PCT (polycyclohexylenedimethylene terephthalate) rated UL94 V-0 — the material self-extinguishes within 10 seconds in a vertical burn test, which is the standard requirement for components inside a plenum or equipment enclosure.","metaTitle":"78548-220HLF BERGSTIK II 20-Pin Unshrouded Header","metaDescription":"Amphenol ICC (FCI) 78548-220HLF — 20-position, dual-row, unshrouded pin header, 0.100\" pitch, 15 µinch gold plating.
