EVERLIGHT 19-21SURC/S530-A3/4T 产品概述
一、产品概述
19-21SURC/S530-A3/4T 为台湾亿光（EVERLIGHT）生产的0603贴片红色发光二极管（SMD LED）。单颗独立二极管封装，透明无色透镜，标准0603体积，适用于对尺寸、光学一致性和成本都有严格要求的消费电子和指示类产品。发光颜色为红色，典型主波长632nm，适配常见视觉指示与低亮度显示需求。
二、主要电学与光学参数
- 发光颜色：红色
- 峰值波长：632 nm（典型），波长范围约624 nm
- 正向电压 Vf：典型 2.0 V（工作电流 25 mA 时）
- 额定正向电流 If：25 mA
- 最大功率耗散：60 mW
- 发光强度：37 mcd ~ 56 mcd（视角 100°）
- 发光角度：100°（半强度角）
- 工作温度范围：-40 ℃ 至 +85 ℃
三、封装与机械特性
- 封装形式：0603（贴片）
- 透镜：无色透明，适合获得较宽的出射角与均匀光分布
- 二极管配置：独立单颗器件，便于回流焊装配与分散布局
该尺寸可实现高密度布板，适合空间受限的移动设备与小型指示面板。
四、应用与设计注意事项
- 典型应用：状态指示灯、键盘背光、仪表指示、便携电子产品和装饰照明的微型指示点。
- 驱动建议：为保证稳定与寿命，建议使用恒流驱动或在串联限流电阻的稳压电源下使用；典型限流电阻可按 R = (Vsup - Vf) / If 计算并留有余量。
- 散热与可靠性：单颗功耗低，但在高密度或高温环境下需注意PCB散热与热堆叠，避免长期超过额定结温。
- 焊接工艺：兼容常规回流焊流程，建议遵循厂方推荐的回流温度曲线以减少透镜与焊盘应力。
五、可靠性与包装
- 工作温度范围宽，适合工业级温度要求的短期应用。
- 常见包装为卷带（Tape & Reel），便于贴片机取放与量产。下单时注意确认卷带方向与单位数量。
六、选型与采购建议
在选择时关注发光强度等级与波长公差以保证视觉一致性；若用于群组显示或色彩匹配场景，建议按同一批次下单并对光学参数进行筛选。对于需要更高亮度或更窄发散角的场合，可咨询替代型号或不同封装选项。

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.
