YLED0805W 产品概述
一、产品简介
YLED0805W（品牌：YONGYUTAI/永裕泰）是一款白光贴片发光二极管，采用标准0805封装，提供高亮度、小尺寸、长寿命的指示与显示解决方案。二极管为独立单体结构，便于点对点驱动和阵列排布，适合各种消费电子、仪表与照明指示场合。
二、主要参数
- 发光颜色：白色
- 正向压降（Vf）：2.6 V ~ 3.0 V
- 额定正向电流（If）：30 mA（连续）
- 发光强度：360 mcd（典型）
- 发光角度：120°
- 工作温度：-40 ℃ ~ +85 ℃
- 封装：0805（≈2.0 × 1.25 mm）
- 二极管配置：独立二极管
三、电气与光学特性说明
正向压降范围随批次与工作电流、温度略有变化，设计驱动时应以最大3.0 V计算余量。尽管额定电流为30 mA，为延长寿命与降低功耗，推荐常规应用采用20 mA驱动；必要时可短时脉冲至30 mA。功耗估算：P ≈ Vf × If（例如3.0 V × 30 mA ≈ 90 mW），热管理通常较为宽松。120°的大视角保证从较大视域范围内均匀可见。
四、封装与焊接建议
0805小封装适用于自动贴装与回流焊工艺。建议遵循无铅回流曲线（例如SAC305），峰值温度不超过260 ℃，并注意焊接热冲击控制以免影响光通与可靠性。焊盘设计按0805标准推荐，留足焊盘面积与焊膏量以避免翘曲与冷焊。
五、驱动与电路注意事项
- 恒流驱动优于恒压限流，能保证亮度一致性。
- 若使用限流电阻，R = (Vsupply − Vf) / If（示例：5 V 至 20 mA，取 Vf = 2.8 V，则 R ≈ 110 Ω）。
- 对于并联多个LED，建议每颗采用独立限流元件以保证一致性。
- 考虑温度升高导致 Vf 降低，应在最坏情况下校核电流。
六、安装、存储与可靠性
- 运输与贴装时注意静电防护（ESD）。
- 为防潮吸湿，建议干燥包装保存，开封后若超过常温高湿环境需按规范回烘烤处理。
- 工作环境温度应控制在额定范围内，超温会加速光衰与寿命下降。
七、典型应用
适合指示灯、按键背光、仪表盘、消费电子指示、家电面板、信号灯及一般点光源照明应用。凭借小尺寸与较宽视角，亦适用于密集阵列与面板均匀照明设计。

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.
