XL-3528UYC 3528 黄色贴片LED 产品概述

XL-3528UYC 是 Xinglight(成兴光)推出的一款 SMD 3528 黄色贴片发光二极管,面向指示灯、背光和一般照明点光源应用。器件采用透明无色透镜、120°宽视角设计,颜色偏向暖黄色,视觉效果柔和且亮度稳定。该器件在标准贴片生产流程中易于加工并具备良好的性价比。

一、主要特性与优势

  • 发光颜色:黄色(视觉暖黄、接近 588nm 峰值)
  • 峰值波长:588 nm(波长范围 585–595 nm)
  • 正向电压(Vf):典型 2.4 V
  • 额定正向电流:20 mA(最大)
  • 功率:50 mW
  • 发光强度:400 mcd(在额定电流下)
  • 发光角度:120°(宽视角,适合指示与背光)
  • 透镜颜色:无色透明
  • 封装:SMD 3528(尺寸约 3.5 × 2.8 mm)
  • 载带方式:正贴(载带装配,元件面向上)
  • 工作温度范围:-20 ℃ 至 +80 ℃

这些参数使 XL-3528UYC 在常规电子指示、面板标示、工具仪表、家电指示灯及小型装饰照明等应用中表现良好。

二、电气与光学参数说明

  • 正向电压 Vf 约为 2.4 V,随电流和温度会略有变化;实际电路设计应考虑 Vf 的容差。
  • 在 20 mA 条件下,典型发光强度为 400 mcd;若降低电流(例如 10–15 mA),亮度会线性下降,但器件寿命和可靠性会提升。
  • 峰值波长 588 nm 属于暖黄色范畴,视觉上偏暖,适合提示与警示色应用。
  • 宽视角(120°)可提供较为均匀的出光分布,减少对准精度要求。

示例限流电阻计算(以 5 V 电源为例):

  • R = (Vs − Vf) / If = (5.0 − 2.4) / 0.02 = 130 Ω(可选 120–150 Ω 标准值,实际按亮度与功耗权衡选择)

建议在设计中对驱动电流进行降额(例如工作电流设置在 10–15 mA)以延长寿命并降低热衰。

三、封装与机械特征

  • 封装形式:SMD 3528,适用于自动贴片(SMT)生产线。
  • 透镜:无色透明透镜,出光均匀,适合需要明显发光但不需色散的场景。
  • 载带方式为正贴(元件面向上),便于视觉检验与贴装定位。
  • 建议根据标准 3528 PCB 封装布局设计焊盘和锡膏模板,保证焊接可靠性与热传导。

四、典型应用场景

  • 面板与面向用户的指示灯(仪表、家电、通信设备)
  • 背光与装饰照明(控制面板、标识灯)
  • 信号指示与状态显示(开关、指示灯条、指示矩阵)
  • 低功耗指示与电路调试标识

由于工作温度上限为 +80 ℃,不建议用于高温或严苛户外环境中的直接照明或高功率应用。

五、使用与焊接建议

  • 采用回流焊进行 SMT 贴装;建议遵循 IPC/JEDEC J-STD-020 的回流温度曲线(峰值温度一般不超过 260 ℃,且高于 217 ℃ 的时间应控制在规范允许范围内)。
  • 存储与搬运时应注意防潮、防静电:在潮湿条件下长时间存放的元件可能需要回流前预烘烤处理。建议按照供应商提供的储存说明进行管理。
  • 为保证光输出与一致性,焊接后应避免在高温环境下长时间回流或暴露。
  • 推荐在 PCB 设计中预留适当散热路径(虽然单颗 3528 LED 功率不大,但长期高电流使用会导致温升影响光衰与寿命)。

六、散热与寿命建议

  • 虽然单颗功率仅 50 mW,但在密集布局或高环境温度条件下,应考虑散热和热隔离设计。
  • 建议工作电流适度降额(例如 50–75% 的最大额定电流)以显著提高寿命和保持光衰低速化。
  • 常规工作环境下(室温、适当电流)可获得长期稳定的光输出;如要求高可靠性,应在设计验证阶段进行老化与热循环测试。

七、包装与订购信息

  • 封装:SMD 3528,载带包装(正贴)适用于自动贴片机。
  • 建议按工程样品与量产需求与供应商确认最小订购量、包装卷带长度与出货前的品质检验规范。

总结:XL-3528UYC 是一款面向常规指示与小功率背光应用的黄色 SMD LED,具有稳定的光色、宽视角和兼容 SMT 生产工艺的封装特性。合理的驱动与热管理能显著提升其使用寿命与可靠性,适合在消费电子与工业控制等多种场景中应用。若需更详细的曲线(IV 曲线、光谱曲线、视角坐标)或回流曲线与物料表(MSDS/ROHS/可靠性测试报告),建议向 Xinglight 或成兴光供应商索取完整技术数据手册(TDS)。

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.
