APT2012SYCK 产品概述
一、概述
APT2012SYCK 是 Kingbright 推出的表面贴装微型黄色发光二极管（LED），采用 0805 封装，透镜为无色透明型。该器件在典型驱动条件下显示纯净的黄色发光（峰值波长 590 nm），适用于状态指示、背光点阵、仪表面板及空间受限的通用照明指示场合。
二、主要性能参数
- 发光颜色：黄色
- 峰值波长：590 nm
- 正向电压 (Vf)：典型 2.0 V（在 If = 20 mA）
- 额定正向电流：20 mA（工作参考值）
- 功率消耗：75 mW（器件最大功耗）
- 发光强度：150 mcd（If = 20 mA，典型）
- 发光角度：140°（宽视角，均匀可视）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装：0805（约 2.0 mm × 1.25 mm）
- 透镜：无色透明
三、封装与光学特性
0805 小体积封装便于高密度贴装与自动化生产。透明透镜设计在不扩散颜色的前提下提供较高的中心亮度，同时 140° 的发光角度保证了较大范围的可视性，适合指示与一般照明用途。由于为透明透镜，灯色边缘相对清晰，需在外观一致性应用中注意与扩散型灯的匹配。
四、热管理与可靠性
器件额定功率 75 mW，为保证长期可靠性建议：
- 在 20 mA 驱动下器件功耗约为 40 mW（2.0 V × 20 mA），低于最大额定功耗，但在封装密集或高环境温度时需考虑热累积。
- 工作环境温度上限 +85 ℃，如长期工作在高温区应进行必要的退额定（derating）。
- 建议在 PCB 设计中保留适当的铜箔散热区并避免与高热源元件紧邻布置。
五、典型应用
- 面板/按键状态指示灯
- 仪器仪表、医疗设备指示
- LCD/LED 背光点阵补光
- 工业控制面板、消费电子指示灯
六、使用建议与注意事项
- 驱动与限流：推荐使用限流电阻或恒流驱动。例：在 5 V 系统下，限流电阻可按 R = (Vs - Vf) / If 计算，代入值为 R ≈ (5 V - 2 V) / 20 mA ≈ 150 Ω。
- 焊接与回流：适用于常规表面贴装无铅回流工艺；建议遵循元器件供应商给出的回流曲线以保证焊接可靠性。
- 静电防护：LED 对静电敏感，封装在生产与存储过程中应采取 ESD 防护措施。
- 光学配合：若需更柔和或漫射的视觉效果，可在封装上使用外部扩散罩或选用扩散透镜型号以匹配系统外观一致性。
总结：APT2012SYCK 以其小巧的 0805 封装、清晰的黄色发光与宽视角特性，为各类指示类与小型照明应用提供了稳定、易集成的光源选择。在设计时注意热管理与限流保护，可获得长期稳定的使用表现。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
