YLED0402W 贴片LED产品概述

YLED0402W是永裕泰(YONGYUTAI)推出的超小型白色贴片发光二极管,采用行业通用0402封装,兼具高亮度、低功耗与宽温适应性,适用于高密度PCB布局的各类电子设备指示、背光场景。

一、产品基本定位

该产品属于微型高亮度白色贴片LED,核心定位为紧凑空间下的状态指示、辅助背光及小型照明需求,支持宽温度范围工作,可满足消费电子、工业控制、汽车电子等多领域的低功耗应用场景。

二、核心性能参数详解

YLED0402W的参数设计兼顾了光效、电气稳定性与环境适应性,关键参数如下:

1. 光色与光学表现

  • 发光颜色:纯白色,搭配黄色透镜设计,可优化光输出均匀性,减少眩光;
  • 色温范围:8513K~35677K(实际应用中覆盖冷白至超冷白区间,适配不同视觉需求);
  • 发光强度:额定430mcd,在0402封装级别中属于较高亮度,确保远距离/弱光环境下清晰可见;
  • 发光角度:120°宽视角,光线覆盖范围广,无明显中心暗区,视觉体验均匀。

2. 电气特性

  • 正向压降(Vf):2.6V~3V(典型值约2.8V),参数一致性好,便于电路设计时的限流电阻匹配;
  • 正向电流(If):额定20mA,短时间脉冲电流可适当提升(需参考官方 datasheet 具体规格);
  • 功率:额定70mW,低功耗设计,适合电池供电的便携设备(如智能手表、蓝牙耳机)。

3. 环境适应性

  • 工作温度:-40℃~+85℃,覆盖低温户外、高温工业环境,满足汽车电子、户外传感器等严苛场景;
  • 存储温度:兼容-55℃~+125℃(行业常规,便于仓储运输)。

三、封装与布局优势

YLED0402W采用0402封装(公制1005,尺寸约1.0mm×0.5mm×0.5mm),是贴片LED中体积最小的规格之一,具备以下优势:

  1. 高密度布局:可在1cm² PCB上实现数百个LED的排列,适合小型化设备(如智能手环、遥控器);
  2. 焊接兼容性:支持回流焊、波峰焊等常规SMT工艺,与其他0402封装元器件兼容;
  3. 独立二极管配置:每个LED为独立单元,无串扰,可单独控制亮度/开关,便于实现复杂指示逻辑。

四、典型应用场景

结合产品参数与封装特点,YLED0402W的核心应用场景包括:

  1. 消费电子:智能手机状态指示(充电、通知)、智能手表背光、蓝牙耳机配对灯;
  2. 小型便携设备:遥控器、电子秤、MP3播放器的功能指示灯;
  3. 工业控制:微型PLC、传感器模块的状态显示(电源、信号输入);
  4. 汽车电子:车载小屏背光、仪表盘辅助指示、胎压监测模块指示灯(宽温适配);
  5. 智能家居:智能开关、温湿度传感器的工作状态提示。

五、品质与可靠性

永裕泰作为专业LED制造商,YLED0402W具备以下品质保障:

  1. 参数一致性:批量生产中Vf、发光强度偏差控制在±5%以内,避免电路设计差异;
  2. 环保合规:符合RoHS、REACH等国际环保标准,无铅无镉,适配绿色制造需求;
  3. 长寿命设计:额定工作条件下寿命可达50000小时以上,可靠性满足长期使用需求。

六、选型注意事项

  1. 限流电阻匹配:需根据实际工作电压(Vcc)计算限流电阻R=(Vcc-Vf)/If,避免过流损坏;
  2. 散热设计:高密度布局时需注意PCB散热,避免局部温度过高;
  3. 透镜保护:黄色透镜为光学组件,避免尖锐物体刮擦,影响光效。

以上为YLED0402W的核心产品概述,具体应用需参考官方 datasheet 获取详细电气、光学及可靠性数据。

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.

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
