WS2813E 产品概述
一、产品简介
WS2813E 是 worldsemi 推出的 SMD5050 封装智能全彩 LED 像素灯，集成单线串行控制与断点续传功能，适用于高密度点光源与可编程照明场景。高性价比设计适配商业照明、装饰照明及舞台背景屏等多种应用（注意防潮，请查阅规格书中对应具体内容）。
二、光学与发光参数
- 波长范围：R 620–625nm，G 515–525nm，B 465–475nm。
- 发光强度（典型值）：G 1150mcd，R 360mcd，B 220mcd。
该组合在多色混合时可实现宽色域与稳定的白光还原，绿色亮度优势明显，适合对绿色饱和度有要求的场景。
三、电气与信号特性
- 工作电压：3.5V ～ 5.3V，兼容常见 5V 系统。
- 静态电流：0.7mA（单像素待机参考值）。
- 数据速率：800Kbit/s，标准 WS* 系列兼容的单线协议。
- 内置单向传输功能，支持断点续传，当链路中断或像素失效时可维持后续像素数据传输，提高整链可靠性。
四、环境与机械规格
- 工作温度：-25℃ ～ +85℃，适应室内及多数室外环境（如有极端环境请参考规格书）
- 外形尺寸：宽度 5mm，高度 1.65mm，SMD5050 封装便于贴片生产与高密度排列。
五、应用场景
适用于LED灯带、像素屏、建筑轮廓照明、背光条及舞台装置。其断点续传与单向传输增强了长链应用的可靠性，便于大规模串接部署与故障隔离。
六、封装与品牌
- 品牌：worldsemi
- 封装：SMD5050，表面贴装工艺，兼容自动贴片与回流焊流程。
七、包装、储存与使用建议
- 注意防潮处理：SMD 器件对湿度敏感，建议按规格书中的湿敏等级（MSL）和回流焊前的干燥要求进行保存与烘干处理。
- 电源与地线布线要充分考虑电压降与散热，长链应用建议分段注入电源以保证亮度一致性。
- 信号线长度与驱动能力需按 800Kb/s 协议规范设计，必要时添加驱动芯片或缓冲器。
总结：WS2813E 以 SMD5050 的体积和 worldsemi 的控制方案提供稳定的色彩表现、800Kbit/s 的高速数据传输与断点续传能力，是追求可靠性和成本效益的像素级照明方案。更多详细电气特性与封装尺寸、公差及湿敏等级，请参阅官方规格书。

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.
