Inquiry
We've looked over your inquiry and the RX24 series should cover what you need, with power ratings form 50W up to 1000W and a resistance range of 4Ω to 10Ω, though we can customize that if your load requirement differ—just let us know tolerance you're targeting, as the standard ±5% works for most LED appliction but tighter specs are possible.
The anodized aluminum housing is what handles the heat—these things can run at -55°C to +275°C without breaking a sweat, and the ceramic core with resistance alloy wire keeps performance stable even under continuous load, which is usually the main concern for automotive LED turn signal and brake light setups where hyper flash is the issue you're trying to solve.
Documentation-wise we provide full COAs with HPLC and TDS data (usually within 2-3 business days after order confirmation), and for initial samples we can send a spec sheet and 3rd-party test report if your QA team needs that before committing to production MOQ.
Payment terms are typically T/T with 30% deposit and 70% before shipment for new accounts, though we can discuss L/C for larger volumes; shiping is FOB Shanghai or CIF depending on your preference, and lead time is roughly 20 days or so for standdard specs, but custom resistance values or terminal shapes might add a week.
A detail buyers don't always ask about—the tinned iron terminals are fine for most connections, but if you're working in high-vibration environments or salt spray conditions, we'd recommend the stainlss steel option which holds up better over time, though it does add about 15% to the unit cost.
For your LED load resistor application, 50W to 200W units are what most automotive buyers go with, and we usually have stock on 4Ω, 6Ω, and 8Ω values in the RX24-50W and RX24-100W sizes so our company can ship within a week after payment clears.
For custom resistance values like 8Ω, MOQ is 500 pieces, and lead time is roughly 2-3 weeks after order confirmation. Standard values like 5Ω ship from stock in 3-5 days.
Yes, we can supply test reports per AEC-Q200 standards, including thermal shock and vibration tests. Just let us know which specific tests you need documented.
The anodized coating gives good salt spray resistance—tested up to 48 hours per ASTM B117. It's fine for under-hood use, but for extreme salt exposure, we'd recommend a conformal coating.
Tinned iron is standard and works for most applications. Stainless steel terminals are better if you need extra corrosion resistance, like in coastal areas or high-humidity engine bays.
Yes, we offer the RX24 series up to 1000W at 10Ω, but the physical size increases with power—1000W is about 150x50mm. Standard tolerance is ±5%, and we can adjust the temperature coefficient if needed.
