YLED0805G（0805）翠绿色贴片LED — 产品概述
一、产品概述
YLED0805G 是永裕泰（YONGYUTAI）出品的一款0805封装翠绿色发光二极管，面向小间距指示与背光应用。器件峰值波长525nm（波长范围516–534nm），呈明亮翠绿色光色，发光角度120°，单粒光强典型值430mcd。标准工作电流为20mA，最大功率耗散70mW，适用工作温度范围-40℃至+85℃，正向压降Vf范围2.4V–3.1V。
二、主要性能参数（关键信息）
- 封装：0805（SMD）
- 发光颜色：翠绿色（峰值525nm，516–534nm）
- 正向电流（If）：20mA（典型工作值）
- 最大耗散功率：70mW
- 正向压降（Vf）：2.4V ~ 3.1V
- 发光强度：430mcd（典型，If=20mA）
- 发光角度：120°
- 工作温度：-40℃ ~ +85℃
注：光强与电流、环境温度有关；数据应以厂家完整数据手册为准。
三、典型应用
- 仪表、面板状态指示灯
- 手机、可穿戴设备、家电面板小型指示/背光
- 消费电子指示与符号照明
- 传感/光学校准参考光源（低功耗）
0805小封装适合空间受限的高密度贴片布局。
四、电气与热设计建议
- 电流限制：建议在每颗LED上使用恒流源或串联电阻限流，工作电流不超过20mA；为提高寿命，连续工作常规推荐10–15mA。
- 串联电阻计算示例（以5V供电、目标If=20mA）：R = (5V − Vf)/0.02A。取Vf下限2.4V时R≈130Ω；为容忍Vf变化可选150Ω。3.3V供电时需注意Vf接近供电电压，宜采用恒流驱动或更小电流。
- 功率与散热：单颗功耗约Vf×If（最大约62mW），接近器件70mW极限。0805体积小，热阻较高，长时间高电流工作需降流或多颗并联分摊热量。
五、贴装与可靠性注意
- 焊接工艺：支持回流焊，遵循无铅回流温度规范（参考制造商回流曲线）。建议预热、峰值温度与时长按PCB装配工艺控制，避免超温及重复高温循环。
- 储存防潮：小封装LED对回流焊接前的吸潮敏感，建议开封后在规定时间内贴片或按厂家建议烘烤处理。
- 环境与寿命：避免长时间在高温高湿或强电流条件下工作，按用途适当降额使用以延长亮度保持率与寿命。
六、选型与实施建议
YLED0805G 适合对体积和亮度有平衡要求的绿色指示场合。选型时注意匹配工作电压、驱动方案与热管理策略；需精确亮度一致性时建议按批次筛选并参考光电特性曲线（If对Iv/光谱曲线）。为获得最佳可靠性与一致性，采购前索取并核对永裕泰的完整规格书与生产批次数据。
总结：YLED0805G 提供在微型封装下较高的光强与宽视角，是面板指示与紧凑型电子产品的常用绿色LED解决方案，但在驱动与热设计上应给予足够重视以确保长期稳定性。

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.
