The 5A per-contact rating and UL94 V-0 black insulation suit it for general-purpose signal and low-power distribution inside an enclosure. The -65°C to 125°C operating range means it handles industrial cabinet thermal swings without issue. ## What the 5A rating means for the fit 5A per contact is the maximum rated current at ambient — the real-world limit drops if you pack the header into a high-temp cabinet or run all three circuits at once.","metaTitle":"78511-203HLF BERGSTIK® II Header, 3 Pos, 2.54mm, 5A","metaDescription":"Amphenol BERGSTIK® II unshrouded header, 3 positions, 0.100\" pitch, 5A rating, gold plating.
