XL-3020UYC-FJ 是成兴光(Xinglight)推出的一款小尺寸贴片发光二极管,封装为 SMD 3.0 × 2.0 mm 方形灯头。外观采用无色透明透镜、独立二极管设计,发出反极黄色(588 nm 峰值)光,适用于面板指示、背光、信号指示及消费电子小型点光源等场合。
该器件在 20 mA 驱动下提供约 1.15 cd 的亮度,120° 的视角使其在较宽观察角内均有良好可见性。典型 Vf 在 1.8–2.2 V 之间,最大功耗 50 mW,按最大 If 20 mA 与 Vf 上限 2.2 V 计算,封装耗散约 44 mW,仍在额定功率范围内,但长期工作应注意热管理与电流控制。
推荐恒流驱动或系列限流电阻驱动。以 5 V 电源为例,限流电阻 R = (Vs - Vf) / If。取 Vf 范围计算:
载带为正贴,适合自动贴片机直接贴放。推荐遵循标准 SMD LED 的回流焊工艺,遵循器件厂商的回流曲线与焊接可焊区设计,避免机械应力作用于透镜。贴装时注意极性标识,样品盒或卷带上会有极性标注。
工作环境温度范围宽 (-40 ℃~+85 ℃),但长期高温或长时间高电流运行会加速亮度衰减。存储与搬运请做好防潮、防静电措施,避免高湿、高温及阳光直射。建议在规定保质期内(参考出货包装)使用,并在贴片前进行充分回温除湿。
型号:XL-3020UYC-FJ,品牌:Xinglight(成兴光)。采购时请确认包装形式(卷带、数量)、批次和出厂测试数据(IV 曲线、光谱、光强分布),以满足量产一致性需求。
如果需要,我可以帮您计算不同电源电压下的限流电阻、给出参考 PCB 封装尺寸或提供与常见驱动芯片的配套建议。

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.
