KPTR-3216CGCK 产品概述

一、产品简介

KPTR-3216CGCK 是 Kingbright 推出的 1206 封装反向安装(Reverse Mount)黄绿色发光二极管,专为需要平面或面板背光、正面指示但安装在 PCB 背面的应用而设计。该器件在 20 mA 驱动下提供稳定的黄绿色发光(发光色调偏黄绿色,主波长约 570 nm,峰值波长 574 nm),透镜为无色透明,出光角度大(140°),适合均匀照明和宽视角可视指示。

二、主要电光参数

  • 发光颜色:黄绿色(Dominant wavelength 570 nm,Peak wavelength 574 nm)
  • 正向压降(Vf):典型 2.5 V
  • 额定正向电流:20 mA(建议工作电流)
  • 最大功率耗散:75 mW(器件最大允许耗散,应勿长期超过)
  • 在 20 mA 时电功率:约 2.5 V × 20 mA = 50 mW(处于最大 75 mW 以内)
  • 发光强度(Iv):50 mcd(@ 20 mA)
  • 发光角度:140°(视角宽,出光分布均匀)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 透镜:无色透明,便于控制发光色与配色一致性

三、封装与外观说明

KPTR-3216CGCK 采用 1206(3216 英制或公制近似)表贴封装,体积小、便于自动化贴装。反向安装设计意味着器件的发光面朝向 PCB 面下方/面内(具体取决于设计),常用于需要将发光面贴近面板开孔或在电路板正面形成可见指示的场合。透镜为透明无色,适合与彩色面板或扩散罩配合使用以获得期望的视觉效果。

四、安装与驱动建议

  • 驱动与限流:建议使用恒流驱动器或串联限流电阻来控制正向电流。常见电源下限流电阻计算示例:
    • 3.3 V 电源:R = (3.3 V − 2.5 V) / 0.02 A ≈ 40 Ω → 可选 39 Ω 或 43 Ω,电阻耗散 P = I^2·R ≈ 0.016 W(使用 1/8 W 或更高功率电阻即可)
    • 5 V 电源:R = (5 V − 2.5 V) / 0.02 A = 125 Ω → 可选 120 Ω 或 150 Ω,电阻耗散 P ≈ 0.05 W(推荐 1/4 W)
  • PWM 调光:建议使用恒流 PWM 或开关型恒流源进行调光以保证色温稳定和寿命。避免在不受控的超脉冲条件下长期驱动。
  • 焊接与回流:采用 SMT 回流焊工艺时,应遵循厂商推荐的回流曲线及行业标准(如 IPC/JEDEC 指导),避免超过器件热极限,减少应力。反向安装时留意焊盘与器件朝向的一致性,防止反向放置。
  • PCB 设计:为保证散热与焊接质量,设计合适的焊盘尺寸与焊膏覆盖,配合良好的锡量与回流参数。若需要前面板透光,确保面板开孔与器件发光位置对准。

五、热与可靠性注意事项

  • 功率管理:器件最大功率 75 mW,建议工作点(20 mA)产生的功率约 50 mW,有一定余量。但在高环境温度或密集封装条件下,应适当降额使用以延长寿命。
  • 工作环境:适用于 -40 ℃ ~ +85 ℃ 的工业与消费环境。若长时间在高湿、高温或振动环境中使用,请做额外可靠性评估。
  • ESD 与静电防护:LED 对静电敏感,装配与测试过程中请采取静电防护措施(佩戴防静电手环、使用防静电工作台等)。

六、典型应用场景

  • 面板/键盘指示灯(隐藏式或透面板式指示)
  • 仪器仪表与工业控制面板的平面指示或背光
  • 消费电子产品指示(如机顶盒、家电面板)
  • 室内小型装饰照明与背光点阵显示
    由于宽视角(140°)和稳定的黄绿色发光,该型号适合需要均匀、宽角度可视性的应用。

七、订购与储存提示

  • 选购时请向供应商确认包装形式(卷带、盘装等)与物料编号,避免混淆方向性或装向。
  • 储存条件:建议在干燥、常温、避免阳光直射的环境中储存,若长期存放请按 SMD 器件防潮包装要求处理(必要时烘干处理后再回流)。
  • 合规性:如需满足 RoHS 或其他环境法规,请向供应商索取相应合规声明或证书。

总结:KPTR-3216CGCK 以其 1206 小型封装、反向安装形式、宽视角和稳定的黄绿色光谱,适合各种需要平面指示与背光的应用。在设计中关注限流、散热与焊接工艺,可以获得长期稳定可靠的指示效果。若需进一步的机械尺寸、回流曲线或完整数据表,建议参考 Kingbright 官方资料或联系授权分销商获取完整技术手册。

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.
