EVERLIGHT 42-21SYGC/S530-E2/TR8 产品概述
一、产品简介
42-21SYGC/S530-E2/TR8 为亿光（Everlight）黄绿色高亮SMD LED，采用透明透镜（clear），发光面小且光束集中。典型应用为状态指示、光点显示、仪表面板与精确指示场合，适合要求小光斑、高对比度的场景。
二、主要电光参数
- 发光颜色：黄绿色（Yellow/Green）
- 峰值波长：575 nm，典型主波长 573 nm
- 正向电压（Vf）：约 2.0 V（IF = 20 mA）
- 额定正向电流：20 mA（典型驱动）
- 发光强度：342 mcd（IF = 20 mA，典型值）
- 发光角度：20°（集中窄角光束）
- 透镜颜色：无色透明
- 封装：SMD，外形约 3.2 × 2.4 mm（裸灯体直径标注 1.8 mm）
三、特性亮点
- 窄视角（20°）：适合需要指向性与高亮度密度的显示与指示应用。
- 高亮度：在20 mA下342 mcd典型值，视觉清晰。
- 小型SMD封装：便于自动贴装与高密度PCB布局。
- 透明透镜保证色泽纯净、色偏小。
四、典型驱动与电路建议
为确保稳定与寿命，建议使用恒流驱动或在电源与LED间串联限流电阻。示例电阻计算：
- 5 V 电源：R = (5.0 − 2.0) / 0.02 ≈ 150 Ω（取标准值150 Ω）
- 3.3 V 电源：R = (3.3 − 2.0) / 0.02 ≈ 65 Ω（可取68 Ω）
实际设计时应考虑驱动器余量与温度影响，建议以恒流驱动为优先方案。
五、封装与贴装注意
- 包装形式 TR（Tape & Reel），便于自动化贴装。E2/S530 为厂方内部分档/批号标识。
- 请参照厂方推荐焊盘与回流曲线，避免超温或长时间高温停留。
- 具ESD敏感性，生产与测试时应采取静电防护措施（接地、手腕带、导电工作台等）。
六、可靠性与储存
- 建议依照厂家湿敏等级（MSL）要求储存与回流前干燥处理，减少湿气导致的焊接缺陷。
- 长期高电流或高结温会加速亮度衰减，建议在额定条件下运行并留余量以延长寿命。
七、应用场景
适合工业与消费电子中的指示灯、仪器仪表指示、车载等级以外的一般指示、精密点光源及光学配合显示场合。
八、采购与选型提示
下单时确认所需光强档位、包装（TR卷带）与批次要求。具体焊盘尺寸、回流曲线、最大额定值与可靠性测试数据请以亿光官方数据手册为准，以保证设计与生产一致性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
