16-216/T3D-AQ1R2TY/3T — EVERLIGHT 0402 白光扩散型LED 产品概述

一、产品概述

16-216/T3D-AQ1R2TY/3T 为台湾亿光(EVERLIGHT)出品的超小型 SMD 白光扩散 LED,封装规格为 0402(约 1.0 × 0.5 mm)。器件采用黄色扩散透镜,提供柔和、均匀的白光显示效果,视角宽广,适合用于空间受限且对指示/背光均匀性有要求的便携与消费类电子产品。

二、主要电光参数

  • 发光颜色:白色(扩散,黄色透镜)
  • 正向电压 Vf:典型 2.8 V(驱动电流 5 mA 条件)
  • 正向电流 If:推荐 5 mA(典型驱动)
  • 发光强度:126 mcd(在 If=5 mA 条件下典型值)
  • 发光角度:130°(半值角,扩散透镜带来宽广视角)

三、封装与机械特性

  • 封装:0402 SMD,极其微小的占板空间,便于高密度布局与轻薄化设计。
  • 透镜:黄色扩散透镜,有助于改善点光源感,提高近距离观看的均匀性并降低眩目。
  • 注意:0402 封装体积小,对贴装、焊接与检查要求较高,请在 PCB 过孔与锡膏印刷、拾取放置工艺上做好控制。

四、电气与驱动建议

  • 典型驱动:If = 5 mA,可获得 126 mcd 的亮度。为延长寿命及提高可靠性,可根据使用环境适当降流。
  • 串联限流电阻计算示例:
    • 3.3 V 电源:R = (3.3 − 2.8) / 0.005 = 100 Ω
    • 5.0 V 电源:R = (5.0 − 2.8) / 0.005 = 440 Ω
  • 功率耗散:LED 自身功耗约 Vf×If ≈ 14 mW(2.8 V × 5 mA),热量集中,连续驱动时注意散热与环境温度对光输出的影响。

五、光学表现与典型应用

  • 宽视角(130°)与扩散镜面,适用于状态指示、按键背光、面板指示、可穿戴设备、移动终端与物联网终端的小面积照明或指示。
  • 黄色扩散透镜可使白光更柔和,改善近场视觉体验,减少“点光源”效果。
  • 在对色温和显色性有严格要求的应用(如医疗显示、精确照明)请向厂商获取具体 CCT 与色容差数据并做实测验证。

六、生产与可靠性注意事项

  • 焊接工艺:建议采用标准无铅回流工艺并遵循器件制造商的回流曲线建议,避免长时间高温暴露。
  • 防静电与存储:小体积 LED 易受 ESD 损伤,生产与测试环节需做好静电防护;存储时按常规 SMD 器件防潮、防氧化要求处理。
  • 设计建议:PCB 封装库应精确匹配器件引脚与焊盘尺寸;因封装极小,建议在 PCB 标注极性并在首件检查时确认方向与亮度一致性。
  • 温度与寿命:在高温或连续高电流工况下建议降额使用,并进行可靠性验证以确保长期亮度稳定。

结论:16-216/T3D-AQ1R2TY/3T 以 0402 极小体积、宽视角与扩散透镜的组合,提供了在微型化设备中实现柔和、均匀白光指示的优良选择。根据实际系统电压与使用环境进行限流、热设计与工艺控制,可获得良好的光学性能与长期可靠性。若需更详尽的光电曲线、尺寸图与回流曲线,请联系供应商索取完整规格书(Datasheet)。

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
