We've been supplying these Dupont terminal bar assemblies long enough to know that the copper core is the main reason people come back—it's pure copper, not some plated alloy that degrades after a few thermal cycles, and that makes a real difference in conductivity when you're pushing 300V to 600V depending on the insulation you pick.
Honestly, the specs hinge on what insulation materail you go with; PVC is fine for basic automotive stuff up to maybe 105°C, but if you're running RF or electronics near heat sources, you'll want PTFE since it handles -65°C to +250°C without breaking down in chemical-exposure scenarios.
So for the terminal options, we've got JAE, TE, AMP, JST, Anderson, Ambofu, and a few others, but your MOQ is 1000 pieces, which is usually manageable for a production run—our company can do samples first for confirmation, and that lets you test fitment without committing to the full lot.
It's not great for high-vibration environments like marine application unless you brace the connection points, because terminal crimp integrity can loosen over time if the cable isn't strain-relieved, and we've seen that issue pop up with buyers who skip the mechancial testing step.
We typically have stock on common lengths and colors, but lead time is about 20 days or so for custom orders, and you'll want to confirm the suplier's current test method—they run conduction tests and dimension verification per ISO9001 and IATF16949, but we usually just check the COA batch specs to be sure.
Yes, we can share SGS, TUV, and RoHS reports upon request. Just let us know which certification you need to review.
MOQ is 1000 pieces even for custom orders. That applies to any combination of length, color, or connector type you choose.
Samples are usually ready in 3-5 working days. We provide them for confirmation purposes, but shipping costs are on you unless we agree otherwise.
It can be either tinned or bare copper, depending on your needs. The -65°C to +250°C range depends on the insulation material you pick, not the core coating.
Yes, we can pre-crimp TE, JST, or any of the listed terminals. For mixed insulation types in one order, we’d need to discuss lead time since each material requires a separate production setup.
