YONGYUTAI(永裕泰)YLED0402O 是一款超微型贴片橙色发光二极管(封装:0402 / EIA),外观尺寸仅 1.1 × 0.5 × 0.4 mm。该器件为独立二极管结构,透明平面胶体和无色透明透镜设计,视角宽达 120°,适用于高密度表面贴装(SMT)和自动贴片机生产线,支持红外线回流焊制程并符合 RoHS 环保要求。
当以恒流驱动时可获得稳定亮度。若以限流电阻驱动,电阻 R = (Vsup - Vf) / If。示例:
建议根据实际亮度与寿命要求适当降低工作电流(如 5–15 mA)以延长可靠性和降低自热。
如需我为您的具体电路(供电电压、驱动方式、PCB 布局限制等)给出更详细的配套建议或热管理评估,可提供使用场景与电源条件,我将进一步优化驱动与封装选型建议。

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.
