The 98424-F52-30ULF: Gold flash is a thin gold layer over the base nickel — it provides corrosion protection and a consistent contact resistance for moderate mating cycles, but the flash thickness (~3-5 µinch) means the cycle life is lower than a 15 or 30 µinch gold deposit.
Shrouded 4-Wall with Latch Holder – Vibration-Resistant Mating
This is a key feature for harness builders who need the mated pair to stay together under mechanical shock or cable strain. The housing is molded in UL94 V-0 rated thermoplastic, cream colored, with a keying slot to prevent mis-mating with non-keyed receptacles. The keying slot is a physical polarization feature — it ensures the header and receptacle are oriented correctly before the pins engage.
SMT Termination – Reflow Soldering on the Board
The SMT footprint requires a solder paste stencil and reflow oven — no through-hole wave soldering. The header is supplied in tube packaging, so pick-and-place feeders may need a tube feeder or manual placement.
