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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
