WS2812E-4020 产品概述

一、产品简介

WS2812E-4020 是 worldsemi 推出的高性价比侧发光可寻址 RGB SMD 灯珠,采用 SMD-4P(4×2mm)小型封装,集成驱动与发光单元。模块化、尺寸小、易贴装,适用于像素点阵、灯带、装饰照明及小型显示等需要高密度布置的场合。

二、主要参数

  • 工作电压:5V
  • 数据速率:800 Kbit/s(标准 WS2812 通信协议)
  • 静态电流(断电/待机):0.6 mA(典型)
  • 尺寸:长 4.00 mm × 宽 2.00 mm × 高 1.65 mm
  • 封装:SMD-4P,侧发光结构
  • 品牌:worldsemi

三、光电性能

  • 波长(典型范围):R 620–625 nm;G 520–525 nm;B 449–454 nm
  • 发光强度(IV 测试条件下):G 850–1200 mcd;R 260–380 mcd;B 90–130 mcd
    上述光电参数适用于额定电流条件下的典型值,实际亮度随驱动电流、PWM 占空比及封装透镜角度有所变化。

四、封装与机械特性

WS2812E-4020 采用 4×2 mm SMD-4P 小型封装,侧发光设计便于在薄型或侧向可视产品中实现均匀光学效果。标准贴片工艺兼容 0603/0805 产线,便于自动化贴装与回流焊接。外形适合高密度像素排列,节省 PCB 占用面积。

五、功能特性与电气特性

  • 内置上电复位(Power‑On Reset)与掉电复位电路,确保供电波动或断电时数据和状态可靠复位,减少失步或熄灭现象。
  • 内置恒流驱动与 PWM 调制接口,支持 800 kHz 单线协议,单颗芯片即可按像素寻址。
  • 建议在每个灯珠的电源近端并联 0.1 μF 陶瓷旁路电容,以保证瞬态响应与信号稳定。若 MCU 为 3.3V 输出,建议使用电平转换或保证数据高电平 ≥ VCC × 0.7 以提高通信可靠性;同时可在数据线上串 300–500Ω 抑制振铃。

六、典型应用

适用于:像素灯条、舞台装饰、小尺寸显示屏、可穿戴灯饰、智能家居氛围灯、广告标牌及需要微型化高密度像素控制的场合。侧发光特点尤其适合边缘照明及薄型面板光效设计。

七、使用建议与注意事项

  • 制板与走线:尽量保证 5V 电源回路的低阻抗、较宽的电源与地线,并考虑分段供电以减少电压降。
  • 热管理:连续高亮色彩下单颗发热增加,布板时留意散热路径及元件间距。
  • 焊接工艺:推荐回流温度曲线遵循无铅工艺规范,避免过高温度与长时间保温。
  • 静电与防护:器件对静电敏感,生产与调试环节采取 ESD 防护措施。
  • 兼容性:遵循 WS2812 通信时序规范,多点链式连接时注意信号完整性与总线长度,必要时加信号放大或缓冲。

WS2812E-4020 汇集小体积、集成化控制与侧发光光学设计,适合要求高像素密度与成本敏感型项目,是常见地址able LED 的实用解决方案。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
