  • 最大/典型功率:60 mW
  • 额定正向电流:20 mA(典型工作值)
  • 透镜颜色:无色透明
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装形式:0805 SMD
  • 型号:17-21/R7C-AN2Q1B/4T
  • 品牌:EVERLIGHT(台湾亿光)

(注:更多电气特性如正向电压、视角、光强分布等请参阅官方数据手册以获得完整工程参数。)

三 光学与电气性能特点

该红色LED在标准20 mA偏置下提供稳定的红色发射,透明透镜有助于提高亮度感知与亮度均匀性,同时便于实现较窄的光束控制或较宽的扩散,具体视器件内部结构和封装而定。峰值波长接近639 nm,使得人眼对红光的敏感度与色彩表现达到良好平衡。推荐在规定的最大功率与电流范围内工作,以保证长期可靠性与色温一致性。

四 封装与机械特性

0805(通常为2.0 mm × 1.25 mm)是行业内常见的小型SMD封装,适合高密度PCB布局。无色透明透镜降低了光色偏移的出现几率,有利于多批次一致性管理。具体外形尺寸、引脚布局与焊盘建议请参考厂方机械图与推荐PCB焊盘图。

五 推荐应用场景

  • 消费电子:状态指示灯、触控板/按键指示
  • 通信设备:指示与信号反馈
  • 仪表仪器:状态与告警显示
  • 工业控制面板:工作状态指示
  • 家电与办公设备:电源/工作状态提示灯

注:若用于汽车或安全关键型设备,请事先确认是否满足相关认证与额外可靠性要求。

六 安装与焊接建议

  • 焊接方式:适用于回流焊装流程。建议采用符合行业标准(如IPC/JEDEC)的回流温度曲线,并以厂商推荐的温度/时间为准。
  • 焊盘设计:建议按照厂方提供的推荐焊盘尺寸进行PCB布局,以确保焊接强度与热散逸性能。
  • 散热与限流:0805器件受限于体积与导热能力,建议在电路中使用合适的限流电阻,并在必要处优化PCB铜箔厚度或增加散热路径以降低结温。
  • 清洗:若需清洗,选择对LED封装材料安全的溶剂与工艺,避免高压喷水或超声清洗可能对器件造成机械或光学损伤。

七 可靠性与环境适应性

该器件可在-40 ℃ 至 +85 ℃ 的环境下正常工作,适合多数室内与部分室外环境。为保证长期可靠性,应避免超出额定电流与功率,同时控制回流焊峰值温度和焊接时间。针对潮湿敏感性与长期储存建议参考供应商提供的MSL(湿敏等级)信息。

八 储存与静电防护

  • 储存:建议在干燥、防尘、避光及常温条件下储存,必要时按厂方说明进行防潮包装与烘烤处理。
  • ESD防护:LED对静电敏感,建议在装配和测试过程中严格遵守静电放电防护规范(佩戴接地腕带、使用防静电工作台等)。
  • 认证与合规:如需RoHS、REACH或特定行业认证,请向供应商确认相应证书与生产批次资料。

结语:17-21/R7C-AN2Q1B/4T(0805)以其微型封装、稳定的红色发射和适中的功率设计,适合多种通用指示与状态显示场景。工程设计时建议参照亿光官方数据手册完成详细的电气、热与机械校核,以保证产品性能与可靠性。

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
