XL-2835UBC-02 产品概述
一、产品简介
XL-2835UBC-02 为成兴光（Xinglight）推出的高亮贴片蓝光二极管，采用SMD2835封装。发光颜色为蓝色，峰值波长465nm（范围460–470nm），透镜为无色透明透镜，出光均匀，适合高密度贴片阵列和精细背光应用。
二、主要电气与光学参数
- 发光颜色：蓝色
- 峰值波长：465nm（460–470nm）
- 正向电压（Vf）：3.4V（典型）
- 正向电流（If）：60mA（额定）
- 功率：200mW（最大耗散近似）
- 发光强度：1750mcd（在额定条件下的典型值）
- 发光角度：120°
- 载带方式：正贴（适用于自动贴片机）
- 工作温度：-20℃ ~ +85℃
备注：发光强度与测试条件（电流、光学接收角度）相关，选型时请参照厂商光学曲线。
三、热管理与可靠性要点
在60mA工作点时，器件近似功耗 Vf×If ≈ 3.4V×0.06A ≈ 0.204W，接近标称200mW。长期使用建议做好PCB散热设计：增大焊盘、增加铜厚或使用热 vias。连续长时间工作时可考虑降额（例如80%额定电流）以延长寿命。遵循回流焊工艺要求，峰值温度不宜超过厂家推荐值，回流高温停留时间尽量缩短。操作时注意静电防护（ESD）。
四、电路与选型建议
- 常用限流方式：串联恒流源或串联电阻。电阻计算示例（以5V供电、60mA为例）：R = (5V − 3.4V) / 0.06A ≈ 27Ω，电阻功率 ≈ I^2R ≈ 0.097W，选用0.25W及以上电阻；若使用恒流驱动器，应选定稳定的60mA恒流源并考虑降额。
- 多颗并联时应保证每串通道恒流均分；多颗串联可减少功耗在限流元件上的损失，但需注意系统电压裕度。
- 若追求更长寿命或更稳定的光通量，建议将驱动电流控制在额定值以下（如40–50mA）并结合散热设计。
五、典型应用
适用于指示灯、仪表背光、通用照明模组、小型投影/显示背光以及需要高显色与稳定蓝光源的电子产品。
六、封装与贴装建议
SMD2835（尺寸约2.8×3.5mm）兼容常见贴片工艺。载带为正贴，便于自动贴装。建议参考厂家提供的封装图样与焊盘建议，调整焊膏量与回流曲线以避免过多焊膏引起光学遮挡或热阻升高。
总结：XL-2835UBC-02 在蓝光输出、视角与亮度上具有良好表现。正确的驱动与热设计是发挥其稳定性与寿命的关键。若需更详细的光电曲线、封装图或回流曲线，请联系供应商获取完整数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
