APTD2012LSURCK 产品概述 — Kingbright 红色 0805（2012）LED
一、产品简介
APTD2012LSURCK 为 Kingbright 生产的红色 SMD 发光二极管，封装尺寸为 0805（公制 2012），透明无色透镜设计。该器件在典型正向电流 2mA 条件下提供稳定的发光强度和窄光束特性，适合用于指示、背光与微型显示等空间受限的照明或指示场合。
二、主要电气与光学参数
- 发光颜色：红色
- 波长（主波长）：630 nm；峰值波长：645 nm
- 正向电压（Vf）：约 2.1 V（典型）
- 正向电流（If）：2 mA（额定推荐工作点）
- 功率耗散：75 mW（最大）
- 发光强度：150 mcd（在 2 mA 测试条件下）
- 发光角度：40°（半功率角）
- 工作温度范围：-40 ℃ 至 +85 ℃
三、封装与机械特性
0805（2012）SMD 封装，尺寸小巧，适用于高密度 PCB 布局。透明无色透镜有利于获得更高的亮度与更集中的发光角度。典型焊盘布局与封装尺寸请参照 Kingbright 官方数据手册以保证良好的贴装与焊接可靠性。
四、典型驱动与选型建议
- 驱动电阻计算示例（恒压源）：
- 5 V 供电：R ≈ (5.0 − 2.1) / 0.002 ≈ 1.45 kΩ → 常用 1.5 kΩ
- 3.3 V 供电：R ≈ (3.3 − 2.1) / 0.002 ≈ 600 Ω
- 额定 If 为 2 mA，使用时应避免长时间接近最大功率耗散（75 mW）。若需更高亮度，可采用短脉冲驱动并注意热管理与脉冲宽度限制。
- 若在环境温度较高或多颗并列工作时，应适当降低工作电流以保证可靠性和寿命。
五、可靠性与使用注意事项
- 焊接：遵循无铅回流焊工艺规范，避免超出器件温度极限（参考 Kingbright 数据手册的回流曲线）。
- ESD 敏感：LED 对静电敏感，装配与测试时应采取防静电措施。
- 热管理：尽管单颗功耗低，但在高密度布局或长时间高电流工作时需考虑 PCB 散热与温升。
- 极性识别：贴装前请确认正负极方向（参照产品标识或数据手册焊盘图）。
六、典型应用
- 面板指示灯、状态显示
- 仪器仪表与消费电子指示
- 背光点阵与微型显示单元
- 医疗与通信设备的小型指示器
总结：APTD2012LSURCK 以其小巧的 0805 封装、稳定的红色发光特性（630 nm / 645 nm）和在 2 mA 下 150 mcd 的亮度，适合对空间与功耗有严格限制的指示与照明场景。具体电气、机械及焊接参数应以 Kingbright 官方数据手册为准，选型与设计时建议预留足够的热与电流裕量。

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.
