EVERLIGHT 333-2UYD/S530-A3 黄色直插LED产品概述

一、产品基本定位与核心属性

该产品为台湾亿光(EVERLIGHT)推出的通用型5mm圆形直插LED,主打黄色发光指示功能,适用于各类电子设备的状态提示、小型照明辅助等场景。作为亿光经典指示类LED之一,其核心优势在于光色稳定、亮度均衡、低功耗适配性强,可完美替代传统白炽灯指示,同时兼容主流3.3V/5V电路,是工业、消费电子领域的高性价比选择。

二、关键性能参数详解

1. 电参数:低功耗适配主流电路

  • 正向压降(Vf):2V:处于黄色LED的典型压降范围,与常见3.3V/5V供电系统完全兼容——只需串联简单限流电阻即可稳定工作(如5V电源下串联150Ω电阻,3.3V下串联65Ω电阻),无需复杂电源转换。
  • 正向电流(If):20mA:工业级LED的标准工作电流,既保证足够亮度,又避免过流导致的器件老化加速,长期可靠性有保障。

2. 光参数:黄色辨识度与亮度均衡

  • 波长与峰值波长:中心波长589nm,峰值波长591nm,属于人眼最敏感的标准黄色光区域,比偏红/偏绿的黄色光更易识别,适合设备状态指示(如电源开启、故障告警)。
  • 发光强度:320mcd:处于指示类LED的中等偏上水平,既不会因过亮刺眼(如部分高亮度LED易造成视觉疲劳),也不会因过暗难以观察,适配室内外多种环境(室内无强光下清晰可见,户外弱光环境也能识别)。
  • 发光角度:30°:窄角度发光,光输出集中性好,适合“定向指示”场景(如面板指示灯、小型标识牌),避免光线扩散导致的辨识度下降。

3. 外观与透镜:适配插件安装

  • 灯头类型:5mm圆形:符合传统直插LED的通用尺寸,兼容各类插件式PCB设计,无需特殊模具改造。
  • 透镜颜色:黄色:与发光颜色一致,强化黄色光纯度,减少杂光干扰,提升视觉辨识度。
  • 整体尺寸:D5×8.6mm:灯头直径5mm,总高度8.6mm,体积小巧,适合空间紧凑的电子设备(如小型家电控制板、便携式仪器)。

三、典型应用场景

该LED因性能均衡、成本可控,广泛应用于以下领域:

  1. 电子设备面板指示:电脑/路由器的电源/网络状态灯、家电(空调/洗衣机)的功能指示灯、仪器仪表的工作状态提示。
  2. 小型照明辅助:发光玩具的局部装饰、小夜灯(低亮度辅助照明)、户外小型警示牌(如自行车尾灯辅助指示)。
  3. 工业控制与测试设备:PLC(可编程逻辑控制器)的输入输出指示、测试仪器的信号提示灯,满足工业环境可靠性要求。
  4. 消费电子配件:耳机充电盒的电量指示、智能手环的功能提示灯,适配便携式设备的低功耗需求。

四、可靠性与品质保障

作为亿光旗下产品,333-2UYD/S530-A3具备行业领先的可靠性:

  • 环保合规:符合RoHS、REACH等国际环保标准,无铅焊接兼容,适配绿色制造需求。
  • 长寿命设计:典型使用寿命达10万小时以上(20mA连续工作),远高于传统白炽灯(约1000小时),降低设备维护成本。
  • 抗环境干扰:工作温度范围宽(-25℃至+85℃),可适应低温(北方户外)、高温(家电内部)环境;抗静电能力强(HBM≥2kV),减少生产/使用中的静电损坏。

五、选型与使用注意事项

  1. 电流严格控制:必须串联限流电阻,禁止直接接电源(过流会烧毁LED)。计算公式:R=(V电源 - Vf)/If(V电源为实际供电电压,Vf取2V,If取20mA)。
  2. 焊接规范:焊接温度不超过260℃,单次焊接时间不超过3秒,避免引脚过热损坏芯片;建议使用无铅焊锡。
  3. 静电防护:生产/组装需佩戴静电手环、使用防静电工作台,避免静电击穿内部电路。
  4. 环境适配:避免长期暴露在高湿度(>85%RH)、腐蚀性气体(如硫化氢)环境中,否则会加速引脚氧化,影响寿命。

综上,EVERLIGHT 333-2UYD/S530-A3是一款性能稳定、应用广泛的黄色指示LED,可满足多数电子设备的低功耗指示需求,是工业与消费电子领域的可靠选择。

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
