WS2812C-2020-V1/W 产品概述
一、产品简介
WS2812C-2020-V1/W 为 worldsemi 推出的微型 RGB 晶粒一体化智能灯珠，封装为 SMD-4P（2.2 × 2.0 mm），内置驱动与恒流源，单颗工作电流典型 5 mA（小电流设计）、静态电流 0.5 mA。灯珠采用白色雾状透镜，色彩均匀且防眩光，适用于空间受限的场景与对视觉柔和性有要求的产品。
二、主要规格（典型值）
- 供电电压：3.7 V ～ 5.3 V
- 数据速率：800 kbit/s（兼容 WS281x 系列协议）
- PWM 频率：2 kHz
- 峰值波长：R 624 nm；G 525 nm；B 467 nm
- 波长范围：R 620–630 nm；G 520–530 nm；B 464–470 nm
- 发光强度（单色，典型）：R 130 mcd；G 320 mcd；B 60 mcd
- 工作温度：-40 ℃ ～ +65 ℃
- 外形尺寸：长 2.2 mm，宽 2.0 mm
- 透镜：白色雾状透镜
- 功能：内置上电复位与掉电复位电路
三、功能与亮点
- 小尺寸高集成：2.2×2.0 mm SMD-4P 封装，适配微型化布局，便于贴片自动化生产。
- 内置复位电路：上电/掉电复位保证数据稳定性，降低因电源抖动造成的色彩异常风险。
- 低功耗设计：典型工作电流 5 mA，适合电源受限或需多点布放的系统。
- 平滑雾面光感：白色雾状透镜使混色更均匀，减少点光源感，提升氛围灯表现。
四、引脚与接口（常见接口说明）
- 4 引脚布局（SMD-4P）：VDD、GND、DIN（数据输入）、DOUT（数据输出）。
- 建议在数据线上串联 300–500 Ω 的匹配电阻，靠近第一颗灯珠并在电源线上并联 0.1 µF 陶瓷电容做去耦。
五、典型应用场景
- 汽车氛围灯（微型光源阵列）
- 小家电与便携设备（按钮背光、状态指示）
- 机器人与扫地机（嵌入式装饰与反馈灯）
- 电子琴、乐器类产品的按键背光与演示灯带
- 各类微型装饰灯、可穿戴与物联网终端
六、设计注意事项
- 电源稳定性：建议 5 V 系统中布置合适供电分布，长串灯带需考虑电压降与分段供电。
- 信号兼容：若 MCU 为 3.3 V 输出，单颗芯片供电在 3.7–5.3 V 时通常可直接识别数据，但长线或多级拓扑建议使用电平匹配或缓冲。
- 散热与工作温度：在高密度布局或高环境温度下注意热管理，确保工作环境不超过 -40～+65 ℃。
- 电磁与可靠性：合理布局信号线和电源回流，避免干扰导致数据丢失。
本产品凭借超小尺寸、高集成与饱和色彩表现，特别适合对体积、功耗和视觉体验有较高要求的消费电子与智能产品。若需详细电气特性曲线、时序图或封装库文件，可联系制造商获取完整数据手册与评估样品。

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.
