YLED1206WFT 产品概述

一、产品概述

YLED1206WFT 是 YONGYUTAI(永裕泰)推出的一款高亮度 1206 封装冷白色贴片 LED。单颗为独立二极管,采用黄色平面透镜封装,面向自动化贴片与红外线回流焊制程。该器件在标准工作点(典型正向电流 20mA)下提供良好的发光强度与宽视角,适用于面板指示、背光和一般指示照明等场景。

二、主要技术参数

  • 发光颜色:冷白色
  • 色温(标称):45408K(注:原始资料标注为 45408K,建议与供应商核实以确认实际 CCT)
  • 正向电压(Vf):2.6 V ~ 3.1 V(在 If=20mA 条件下)
  • 正向电流(If):20 mA(典型)
  • 功率:70 mW(最大/标称,见供应商规格书)
  • 峰值波长:450 nm(资料中有 450 nm / 470 nm 信息,请按样品测量)
  • 发光强度:520 mcd(If=20mA)
  • 发光角度:120°
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 二极管配置:独立二极管
  • 透镜颜色:黄色平面胶体
  • 封装:1206(3.2 × 1.6 × 0.9 mm)
  • 包装:EIA 规范带装(适配自动贴片机)
  • 环保:符合 RoHS 要求

三、外观与封装信息

  • 标准 1206 尺寸(3.2 × 1.6 × 0.9 mm),小尺寸便于高密度 PCB 布局。
  • 黄色平面透镜有助于改善出光的均匀性与角度分布,同时在白光中可影响视觉色感,从而达到所需的冷白效果。
  • EIA 标准卷盘包装,适配常见贴片机;封装材料与工艺支持红外回流焊流程。

四、性能特点与设计注意事项

  • 高视角(120°)适合做面光源或指示灯,出光扩散均匀。
  • 在 If=20mA 时可得到约 520 mcd 的亮度(典型),适合中等亮度指示与小面积背光。
  • 正向压降 2.6–3.1V,设计驱动电路时应按最大 Vf 计算限流电阻或恒流源,以保证可靠性。示例:在 5V 电源下、If=20mA 时,限流电阻约 (5V − 3.0V)/0.02A ≈ 100 Ω。
  • 器件标称功率 70mW,热管理上应避免在高温环境长时间满载工作;如在高密度阵列中使用,需评估 PCB 散热与功耗累计。
  • 出光波长与 CCT 数据在资料中存在多项标注(450 nm、470 nm、45408K),采购与规格确认时建议要求供应商提供光谱分布曲线(SPD)与色容差/分bin 报告,以便确保色彩一致性。

五、可靠性、焊接与存储

  • 兼容常规无铅/有铅红外或热风回流焊工艺。建议遵循供应商回流曲线与 IPC/JEDEC 相应的焊接规范(一般无铅回流峰值温度≤260°C,具体以供应商资料为准)。
  • 建议在 SMT 前按干燥包装要求进行开封与回流焊,以降低潮湿相关失效风险。
  • 处理时注意防静电(ESD)防护,避免对 LED 芯片造成损伤。
  • 存储条件:干燥、避光、常温;长时间存放建议按厂家建议的密封干燥包装保存。

六、典型应用场景

  • 仪表、控制面板与指示灯
  • 家用电器与消费电子的指示与装饰照明
  • 小型背光、按钮与键盘背光
  • 状态指示、信号灯与一般照明点光源(非主光源)

七、选型与测试建议

  • 量产前进行样件的光电参数验证(Vf、Iv、色温、显色、光谱、显度与视角)。
  • 如对色温/色容差有严格要求,请与供应商确认 bin 分组与一致性策略。
  • 在阵列或背光设计中,评估温升对 Vf 与光输出的影响,必要时采用恒流驱动并留有热余量。
  • 对于汽车或高可靠性应用,确认是否具备相应的认证与更严格的温度循环、振动与寿命测试数据。

总结:YLED1206WFT 为一款面向自动化贴片、支持回流焊的 1206 冷白光 LED,特点为小尺寸、高视角、良好兼容性与 RoHS 环保合规。采购与应用时建议对其光谱与色温做确认,并根据实际应用做好热与电气设计。

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
