WS2816C-2121 产品概述
一、产品简介
WS2816C-2121 系列是一款面向小间距显示屏和精细灯光控制的高性能智能LED模组，来自 worldsemi。器件集成了驱动与控制电路，支持 16bit 高灰度、断点续传和上电复位，体积小、散热好、功耗低，适合高密度点阵与精细化显示场景。
二、主要技术参数
- 波长：G 522–527 nm；R 620–625 nm；B 470–475 nm
- 发光强度（典型）：R 125 mcd；G 270 mcd；B 40 mcd
- PWM 频率：10 kHz（典型）
- 工作电压：3.7 V ～ 5.5 V
- 静态电流：0.8 mA（典型空闲/待机）
- 工作温度：-25 ℃ ～ +85 ℃
- 发光角度：120°
- 封装：SMD，典型封装 2.2 × 2.2 mm；单颗参考尺寸 长 2.1 mm × 宽 1.0 mm × 高 2.1 mm
- 载带方式：正贴（Tape & Reel）
- 功能特性：内置上电复位电路、断点续传、16bit 高灰度
三、功能与优势
- 高灰度（16bit）带来更细腻的亮度梯度与渐变效果，适合高精度显示。
- 断点续传功能可在通信中断或上电后恢复显示状态，提升系统鲁棒性。
- 内置上电复位电路，简化上电时序设计，保证稳定启动。
- 10 kHz PWM 避免可见闪烁，提升观感并降低声波干扰风险。
- 小尺寸与良好散热特性，便于密集布置和高刷新场景。
四、封装与可靠性
WS2816C-2121 采用 SMD 小封装，适用于贴片工艺的自动化生产。工作环境温度范围宽，制造与散热设计上针对小间距显示进行了优化。器件对湿度敏感，存储与贴装前请严格按规格书进行干燥与回流工艺控制。
五、典型应用场景
- 小间距 LED 显示屏与室内精细化屏幕
- 可穿戴与便携式显示模组
- 精细化背光、标牌、舞台灯光及装饰照明
- 需要断点续传与高灰度控制的智能照明系统
六、使用建议与注意事项
- 电源设计：建议使用稳压 3.7–5.5 V 电源，器件在 5 V 系统中具有最佳兼容性；供电线和 PCB 需做好退耦（建议在每颗模组附近放置 0.1 μF~1 μF 去耦电容）。
- 信号电平：确保控制器输出电平与器件工作电压兼容，必要时采用电平转换。
- 温度与散热：高密度布置时注意热管理与通风，避免长时间高温工作。
- 防潮与储存：器件对潮气敏感，贴片前请按规格书要求进行干燥与回潮预处理。
- 测试与调试：在批量生产前进行亮度、色度一致性及灰度线性测试，以保证显示效果。
七、选型与采购建议
在选型时请结合显示点密度、供电方案与控制器接口要求确认工作电压和逻辑电平匹配；对色彩一致性与亮度有严格要求的项目，建议向供应商索取样片并参考完整规格书与色彩曲线。购买时选择正规渠道，留意封装批次与防潮处理记录，以保证良率与稳定性。

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.
