LTW-006DCG-E2 产品概述

一、本产品简介

LTW-006DCG-E2 为台湾光宝(LITEON)出品的标准表面贴装白光 LED,采用黄色透镜设计,外观为 2-SMD 无引线封装。该器件在常见 20mA 驱动条件下,提供稳定的白色光输出,配合黄色透镜可改善视觉对比或实现特定指示效果,适合面板指示、按键背光及小型照明等场景。

二、主要特性

  • 额定正向电流:IF = 20 mA(典型驱动值)
  • 正向压降:Vf ≈ 3.1 V(典型)
  • 发光强度:Iv = 2400 mcd(在指定测试条件下)
  • 发光角度:2θ1/2 = 110°(宽视角)
  • 发光颜色:白色光(黄色透镜)
  • 封装:2-SMD,无引线,便于高速贴装与回流焊工艺

三、电学与光学参数要点

  • 电流与亮度关系:在 20 mA 时为参考标称亮度,建议在设计中预留一定余量以延长寿命并控制色温漂移。
  • 正向压降容差:Vf 随温度与驱动电流变化,电源设计需考虑最坏情况电压降以保证稳定驱动。
  • 视角与漫射效果:110° 的半功率角提供均匀出光,黄色透镜对光谱有轻微修饰,可增强视觉识别度。

四、封装与机械特性

  • 2-SMD 封装适配常见贴片工艺,支持回流焊;无引线设计减小安装高度,利于紧凑型电路板布局。
  • 透镜材质与颜色:黄色透镜有助于改善光感受但对颜色还原有一定影响,选型时需考虑最终视觉效果要求。

五、典型应用

  • 面板指示灯、状态显示、按键背光、装饰照明、小型仪器与家电指示等。
  • 适用于需要宽视角且对比度增强的应用场景。

六、推荐驱动与使用建议

  • 建议恒流驱动,推荐电流不超过 20 mA;若要求更长寿命或更低功耗,可考虑 5–15 mA 的降流使用以获得线性亮度降低。
  • 上电浪涌保护:避免瞬态电压和过流冲击,建议串联限流电阻或恒流源。
  • 散热管理:虽然单颗功耗低,但在高密度布局或高环境温度下需考虑器件温升对光效与寿命的影响。

七、存储与贴装注意事项

  • 建议遵循 IPC/JEDEC 的贴片元件储存与回流焊工艺规范,防潮包装拆封后应在规定时间内回流焊接。
  • 避免长时间暴露在高温、潮湿和强紫外环境中,以免透镜老化或光学性能退化。

综合而言,LTW-006DCG-E2 以其稳定的光学输出、宽视角与便捷的 SMD 封装,适合各类指示与背光应用。设计时关注驱动电流、正向压降与热管理,能最大化器件性能与可靠性。

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
