XL-HD3535UVA2-A2 是成兴光(Xinglight)出品的一款高效贴片紫外发光二极管,采用 SMD3535-3P 封装与球头透明透镜设计,面向需要宽角UVA照射的工业与消费类应用。该器件在 395nm~400nm 波长范围内输出紫外光,单只功率标称 1W,适合点光源与面光源组合使用。
根据额定功率与正向压降,可推算理论工作电流约 270mA(I = P/V ≈ 1W / 3.7V)。建议采用恒流驱动器并留有余量(降额设计),典型驱动电流可在 200–300mA 范围内选择以兼顾光效与寿命。由于UV LED 对结温敏感,必须与金属基板或良好散热的 PCB 结合使用,保证良好导热路径并尽量降低结温以延长寿命与维持光通衰减性能。
SMD3535-3P 为标准贴片封装,适用回流焊工艺。推荐遵循标准 SMT 回流温度曲线,并控制最大回流峰值温度与时间以防止材料老化。贴装时注意保持透镜表面清洁,避免有机物污染影响光输出。储存及贴装环境应注意湿度管控,必要时进行烘干处理以防潮。
选择时应关注工作结温、驱动电流、平均功率与使用频次。UVA LED 在高温或过流条件下光通衰减较快,建议在实际方案中进行温升测试与寿命加速试验。若需并联多颗使用,优先采用带电流均衡或恒流源的驱动方案,避免单颗过驱。
完整型号:XL-HD3535UVA2-A2,品牌:Xinglight(成兴光)。封装标称 SMD3535-3P,载带包装适配 SMT 贴片机。订购时请确认波长范围(395–400nm)、正向压降及额定功率,以保证与系统其他模块兼容。
如需更详细的电气特性曲线、光学曲线、回流焊工艺参数或样片支持,可提供进一步资料与测试建议。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
