WS2812B-XF01/W 产品概述

一、产品简介

WS2812B-XF01/W 是 worldsemi 推出的一款内置驱动的全彩可寻址 RGB 发光器件,封装为 SMD5050。器件集成单线数字接口驱动电路,支持 800Kbit/s 的数据速率,使用方便,无需外接驱动芯片或复杂外围元件。器件具备上电复位、掉电复位以及智能反向连接保护和过压保护等多重可靠性设计,适用于对体积、可靠性和可控性有较高要求的灯光控制应用。

二、主要技术参数

  • 发光波长(峰值):
    • 红(R):623 nm
    • 绿(G):521 nm
    • 蓝(B):452 nm
  • 发光强度(典型):
    • R:350 mcd
    • G:1050 mcd
    • B:110 mcd
  • 数据速率:800 Kbit/s(单线串行数据接口)
  • 工作电压:3.7 V ~ 5.3 V
  • 静态电流(待机):0.6 mA(单元)
  • 外形尺寸:长度 5.0 mm × 宽度 5.0 mm × 高度 1.57 mm(SMD5050)
  • 封装:SMD5050
  • 品牌:worldsemi
  • 型号:WS2812B-XF01/W

三、功能特性

  • 内置上电复位电路,确保上电瞬间逻辑稳定,避免异常显示。
  • 内置掉电复位电路,电源断开及恢复过程保持器件状态的安全切换。
  • 集成智能反向连接保护功能,防止因电源反接导致的永久损坏。
  • 具有过压保护能力,提升系统可靠性与使用安全性。
  • 支持单线高速数据传输,兼容常见的 WS2812 系列控制协议,便于与常见微控制器、控制器固件配合使用。
  • 无需外部驱动元件,简化 PCB 布局与 BOM。

四、封装与机械信息

  • 标准 SMD5050 封装,5 mm × 5 mm 的占位适合灯带、像素点阵与点光源设计。
  • 厚度(高度)1.57 mm,适用于低矮安装空间的方案。
  • 建议在 PCB 布局时预留适当扩散/散热区域,并考虑信号链路的完整性与电源回流路径。

五、典型应用场景

  • 全彩像素化灯带、像素屏、数码霓虹与广告牌
  • 舞台灯光、装饰照明与家居氛围灯
  • 可穿戴灯饰与智能家居指示灯
  • 教育、创客与工程原型开发(与单片机/控制器配合实现丰富动画效果)

六、使用建议与注意事项

  • 虽然器件不需要外部驱动器件,但仍建议在电源入口处并联适当的去耦电容(如 0.1 μF 至 10 μF)以抑制瞬态和降低噪声,提高系统稳定性。
  • 布线时保证电源线径足够粗短,防止长线带来压降;多点接地回流以降低 EMI 干扰和信号完整性问题。
  • 器件支持单线 800Kbit/s 数据链,链路长度与更新速率有关,长链或高刷新率时需评估信号完整性和时序匹配。
  • 在高亮度或持续全白运行情况下,单颗器件电流会随驱动强度变化,系统设计时应考虑电源与散热裕量;如需精确电流估算,请参考评估板实测或咨询厂商技术支持。

七、兼容性与采购信息

  • WS2812B-XF01/W 兼容 WS2812 系列常用控制协议,易于与现有控制器(如 Arduino、STM32、ESP 系列等)集成。
  • 品牌:worldsemi,标准 SMD5050 封装,便于贴片制造与自动化组装。

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
