APT2012LSECK/J3-PRV 产品概述

一、产品简介

APT2012LSECK/J3-PRV 是 Kingbright 推出的小型表面贴装红色 LED(RED CLEAR),封装尺寸约为 2.0 × 1.3 mm,采用无色透明透镜,提供宽广的发光角度与良好的视觉识别性能。该器件以典型低电流驱动(标称正向电流 2 mA)实现红色发光,适合对尺寸、功耗与可见性有要求的便携式与大批量指示类应用。

二、光学特性与视觉表现

  • 典型发光颜色:红色
  • 标称发射波长:625 nm(典型)
  • 光谱峰值:约 640 nm(峰值位置表征光谱分布)
  • 透镜:无色透明,提供较高的透射率与纯色外观
  • 发光角度:140°(宽视角,适合远近多角度可视指示)

该器件在可见光谱的红色区表现稳定,透明透镜加上宽视角设计,使得在指示灯、状态显示与用户界面中具有良好的可见性与均匀照明效果。

三、电气特性与注意事项

  • 典型正向电压(Vf):1.8 V(在标称 If = 2 mA 条件下)
  • 标称正向电流(If):2 mA(推荐驱动条件)
  • 列出参数中“功率:84 mW”的说明:按 Vf × If,器件在 1.8 V、2 mA 条件下的电功率约为 3.6 mW;因此所给的 84 mW 与此计算不一致。该“功率”项可能指最大允许耗散、光学输出或其他特定测试条件下的数值。建议在最终设计与热管理前,参照 Kingbright 官方数据手册确认“功率”含义与极限参数。

设计时务必通过限流电阻或恒流源控制 If,避免直接连接电源。举例限流电阻计算(取目标 If = 2 mA):

  • 5.0 V 电源:R = (5.0 − 1.8) / 2 mA ≈ 1.6 kΩ
  • 3.3 V 电源:R = (3.3 − 1.8) / 2 mA ≈ 750 Ω

实际工程中应考虑电阻容差、驱动器精度与温度导致的 Vf 变化,留有安全裕量以防过流。

四、热与环境特性

  • 工作温度范围:−40 ℃ 到 +85 ℃

器件为小型 SMD 封装,热阻相对较高,长时间或高频脉冲驱动时需要关注 PCB 的散热布局。建议在 PCB 上为 LED 引脚周围配置适量铜箔以改善散热,并在高密度布板或封装空间受限的场景进行热仿真与测试,确保器件长期可靠工作。

五、封装、安装与焊接建议

  • 封装类型:SMD(2 × 1.3 mm)
  • 焊接:推荐采用回流焊工艺(遵循 Kingbright 的回流曲线与温度上限),避免手焊直接在高温下长时间加热而损伤件体或透镜。
  • 安装注意:小型封装易发生 tombstoning 或偏移,建议优化焊盘比例、锡膏印刷量与贴装压力,按 SMT 常规良率控制流程进行。

另外,避免在贴装与清洗过程中使用对透镜有腐蚀性的溶剂;如需清洗,应使用厂商认可的方法与介质。

六、应用场景

适合用于:

  • 仪表与控制面板的状态指示
  • 消费电子(遥控器、穿戴设备、便携设备)指示灯
  • 网络通信设备与服务器状态标识
  • 工业控制与仪器仪表的指示单元

凭借小型化与低功耗特性,该器件特别适合空间受限且需长期低电流指示的产品。

七、可靠性与选型提示

  • 在批量采购与色彩一致性要求较高的项目中,应向供应商索取色度/强度分档(bin)信息,保证多片器件间颜色与亮度一致性。
  • 确认最大正向电流、最大正向电压、反向电压、峰值电流与瞬态功率限制等极限参数,以免超出器件安全工作区(推荐参照 Kingbright 官方数据手册)。
  • 电气保护:在可能存在反向电压或电源瞬态的应用中,考虑并联反向保护器件或适当限制反向电压。

总结:APT2012LSECK/J3-PRV 是一款体积小、视角宽、适合低电流驱动的红色透明透镜 SMD LED。合理的限流和散热设计配合良好的贴装工艺,可以在多种消费与工业场景中提供稳定可靠的指示功能。请在最终设计前参考 Kingbright 官方完整数据手册,以获取极限参数和回流焊曲线等关键工艺信息。

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.
