XL-TD2012UWC 是成兴光(Xinglight)推出的一款高亮贴片发光二极管,封装为 0805(实际尺寸 2.0mm × 1.25mm 方形灯头),顶部球形发光面,采用黄色透镜封装白光发光体。二极管为独立单灯设计,适合自动贴装(正贴、载带包装),用于要求窄光束和高可见度的指示与背光应用。
该型号在 5 mA 驱动条件下具有高亮度输出,典型 Vf 约 2.9 V,电功耗远低于其最大耗散,计算示例:P = Vf × If ≈ 2.9 V × 5 mA ≈ 14.5 mW。窄 30° 出光角度适合点光源指示与聚焦背光;黄色透镜有助于改善发光均匀性与视感。色温位于冷白范围,适用于需要高显白度的场合。
推荐限流电阻计算(以 5 V 电源为例):R = (Vs - Vf) / If ≈ (5 - 2.9) / 0.005 ≈ 420 Ω(常规选用 430 Ω)。若 12 V 总线并串联多只灯,按串联数重新计算电阻或采用恒流驱动。
型号标识:XL-TD2012UWC,品牌:Xinglight(成兴光),封装:805。若需样片、分档光电数据(IV 曲线、光强分档、色温 bin)或回流曲线建议,请提供具体项目要求以便进一步提供详细技术资料。

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.
