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。
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。
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):
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。
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。
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。
适合用于:
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
