FC-2012UGK-520D5 产品概述
一、产品简介
FC-2012UGK-520D5 为国星光电出品的表面贴装发光二极管（SMD LED），采用0805（2012公制）封装，体积小、亮度稳定，适用于各类指示与背光场合。典型工作条件下，顺向压降 Vf ≈ 2.8V（If = 5mA），在该电流下典型发光强度约 180 mcd，发射波长约 520 nm（绿光）。
二、主要参数
- 封装：SMD 0805（2012，约 2.0 × 1.25 mm）
- 典型顺向电压：2.8 V（If = 5 mA）
- 额定顺向电流：5 mA（建议典型驱动电流）
- 典型发光强度：180 mcd（If = 5 mA）
- 典型发射波长：≈ 520 nm（绿光）
三、产品特点
- 小型化封装，适合高密度贴装与轻薄设备设计。
- 在低电流工况下仍能提供良好亮度，利于节能设计。
- 与常见 SMT 贴装和回流工艺兼容，生产线易集成。
- 光色稳定、制造一致性好，便于批次间配色控制。
四、典型应用
- 仪表与面板指示灯、状态显示；
- 消费电子与可穿戴设备的指示/背光；
- 智能家居、物联网终端指示；
- 小型信号灯与装饰照明。
五、驱动与使用建议
- 必须采用限流措施（电阻或恒流驱动器）。计算公式：R = (Vcc − Vf) / If。
例如 Vcc = 5V、Vf = 2.8V、If = 5mA，则 R ≈ 440Ω，常用 470Ω。 - 支持 PWM 调光，但应避免极低占空比下重复应力导致寿命异常。
- 长期稳定工作建议不超过典型额定电流，避免过流与过热，若需更高亮度请在热管理和寿命评估上做验证。
六、封装与焊接建议
- 参考标准无铅回流焊工艺进行贴装，遵循 JEDEC 类无铅温度曲线，峰值温度一般 ≤ 260°C，实际曲线请以厂家推荐为准。
- 贴片时注意极性识别与贴装方向，具体极性标记以产品外观及包装指示或规格书为准。
- 操作与贴装环境应采取 ESD 防护措施，避免静电损伤。
七、可靠性与存储
- LED 寿命与温度、驱动电流密切相关，长期高温或过流会降低光衰寿命。
- 未开封卷带建议干燥密封保存，避免潮湿；如潮湿敏感等级（MSL）有要求，请按厂方说明回焊前做烘烤处理。
- 出货前建议做按批次的光学、电气抽测以保证一致性。
八、选型与后续工作
为保证设计一致性与可靠性，请在最终采纳前索取并确认国星光电最新的产品规格书（Datasheet）与封装图纸，必要时申请样品做温升、光衰、环境应力等验证。若需符合特殊认证（如车规、医疗等），请与供应商确认对应版本与测试报告。

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.
