SMLEN3BC8TT86 是 ROHM(罗姆)生产的一款蓝光发光二极管(LED),封装为0603(标准表贴微型封装),发光波长为470 nm,颜色为蓝色。器件采用共阴极配置,透镜为无色透明,典型应用为面板指示、信号提示和微型光源场合。
注:在典型工作点 If=5 mA 时,器件自身的功耗约为 Pd = Vf × If = 2.9 V × 5 mA = 14.5 mW,远小于标注的66 mW额定耗散,说明在该工作电流下热裕量充足。
0603 封装体积小,适合空间受限的高密度表贴电路板。共阴极配置常用于多色或多个灯珠集成驱动的情形(共用一端接地/阴极),在设计时应注意驱动端的极性与接线方式。具体焊盘尺寸与丝印位号建议参考 ROHM 原厂封装图和回流焊工艺建议。
为保证稳定亮度,需串联电流限流电阻或使用恒流驱动器。
提示:标注66 mW 为器件允许的最大耗散功率,按照 Pd_max / Vf ≈ 22.8 mA 可估算出理论上可能的极限电流,但长期或重复工作应遵循典型正向电流 5 mA 的推荐值及原厂极限条件,避免超额使用导致寿命下降。
SMLEN3BC8TT86 以其微型0603 封装、470 nm 纯蓝发光、适中的发光强度和宽工作温度范围,适合对空间与功耗有严格要求的指示类应用。在电路设计中应采用合适的限流或恒流驱动,并按原厂装配与可靠性建议进行回流焊与 ESD 管控,确保长期稳定运行。如需最终设计与生产资料,请以 ROHM 官方数据手册为准,以获取完整的机械图、光学分布、回流图与绝对极限参数。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
