Product details

Board Layout Fit — 0.100" Pitch, Unshrouded, Dual-Row

The 78548-220HLF: The 20 positions are loaded across two rows with a 0.100" row spacing, so the board footprint occupies a 10-by-2 array of 0.028" square holes. 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.
