WS2812C-4020-H2 产品概述

一、主要特点

WS2812C-4020-H2 是 worldsemi 推出的 5V 小电流内置驱动 RGB 侧发光 SMD 灯珠(封装 SMD4020)。芯片内置驱动与逻辑电路,具备上电复位与掉电复位功能,支持单线串行控制,工作电流极低(典型工作电流约 5mA),待机静态电流仅 0.6mA,适用于体积受限且需低功耗的差异化照明与指示类产品。

二、规格参数

  • 发光波长:R 622nm~626nm,G 525nm~530nm,B 467nm~472nm
  • 发光强度(典型):R 180 mcd;G 500 mcd;B 120 mcd
  • 数据速率:800 Kbit/s(单线串行通信)
  • 工作电压:3.7 V ~ 5.3 V
  • 静态电流:0.6 mA(待机);典型工作电流:5 mA(全彩/常用驱动条件下)
  • 工作温度:-40℃ ~ +65℃
  • 外形尺寸:长 4.0 mm × 宽 2.0 mm × 高 1.65 mm
  • 封装:SMD4020(侧发光,正贴)

三、电气特性与控制

WS2812C-4020-H2 基于 WS2812C 系列单线协议,数据速率为 800kHz,可串联级联多个灯珠。每个灯珠内置 24 位色彩寄存器(常见 GRB 顺序),主控端发送色彩数据后,灯珠完成内部驱动与 PWM 调光。内置上电/掉电复位电路可保证在电源波动或复位时的稳定性,减少花屏与异常显示。

四、机械与封装说明

SMD4020 小型封装,侧发光设计适合狭长空间或需要侧向出光的产品位置(如鼠标侧沿、键盘侧灯、机箱走线槽等)。正贴(Top-side)安装,兼容常规 SMT 贴装与回流工艺,体积小、提高模块集成度。

五、典型应用场景

适用于需要小体积、多色指示或氛围灯的消费电子与外设产品,例如:鼠标、机械/薄膜键盘、便携音箱、机箱风扇灯环、电子琴与其它乐器、仪器面板等。低功耗特性适合电池供电或功耗敏感设备。

六、设计与使用建议

  • 电源:建议在 3.7–5.3V 范围内稳定供电,考虑加装 0.1uF~1uF 去耦电容靠近灯珠 VCC-GND 以抑制瞬态波动。
  • 信号:数据线建议串联 200–500Ω 抑制反射,并在数据线上采用合适的抗干扰布局;信号接地共地非常重要。
  • 焊接:兼容无铅回流工艺,参考元器件回流温度曲线,避免超过材料允许的热应力;建议在贴片前确认焊膏量与锡膏类型。
  • 散热与布局:虽然单颗功耗低,但大数量并联时应注意 PCB 散热与电源分配,避免电压降引起色差。

七、可靠性与包装

工作温度范围宽(-40~+65℃),适应常见工业与消费环境。出厂通常采用卷带(Tape & Reel)包装,便于贴片机自动化生产。建议在设计验证阶段进行电源抖动、ESD 防护与长期老化测试,以确保多颗级联场景下的稳定性。

总结:WS2812C-4020-H2 以其超小体积、低工作电流、内置复位与单线高效控制的特性,特别适合需要侧发光、节能与高集成度的外设与消费类灯光设计。

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
