APTD3216SYCK 产品概述

APTD3216SYCK 是 Kingbright 推出的一款黄色(黄光)1206(3216 公制)表面贴装 LED,透明无色透镜设计,单个独立二极管封装,适用于面板指示、仪表、消费电子和各种状态显示应用。该型号以稳定的光学性能与紧凑封装为特点,提供可控的光通量和较窄的发光角度,便于在有限空间内实现高可见度的指示效果。

一、主要电学与光学参数

  • 发光颜色:黄色
  • 峰值波长:590 nm(典型)
  • 正向电压(Vf):2.0 V(典型)
  • 典型正向电流(If):20 mA(建议最大常用驱动)
  • 功率(器件额定):75 mW(器件额定或最大功耗,实际电耗与驱动电流相关)
  • 发光强度:800 mcd(在指定测试条件下)
  • 发光角度:40°(半值角,较窄的光束有助于提高视觉集中度)
  • 工作温度范围:-40 ℃ 至 +85 ℃

说明:在 20 mA、Vf ≈ 2.0 V 时,LED 自身耗电约 40 mW(P=Vf×If)。75 mW 可视为器件的允许功耗上限或封装热容限定值,请在实际应用中留余量以保证可靠性。

二、封装与光学结构

  • 封装尺寸:1206(3216 公制),适配常用 SMT 贴片工艺与 PCB 布局;适合高密度板级设计。
  • 二极管配置:独立二极管,便于单点驱动与排列组合。
  • 透镜:无色透明透镜,确保色温与光谱不受过滤影响,光色更纯净,配合 40° 发光角可形成较聚焦的指示光斑。

三、典型应用场景

  • 面板与机箱指示灯(电源、状态、告警指示)
  • 工业与医疗仪器的状态显示
  • 消费类电子产品(路由器、显示器、家电等)状态指示
  • 仪表盘、按钮背光、小型显示模块(在需要较高可视性的点光源处)
    注:若用于汽车或军事等高可靠性场合,请参考供应商的完整资格与认证信息。

四、驱动与电路建议

  • 恒流驱动优先:为保证亮度一致性与延长寿命,推荐使用恒流源或恒流驱动器。
  • 分流电阻计算示例(采用简单电阻限流):
    • 以 5 V 电源驱动:R = (5 V − 2 V) / 20 mA = 150 Ω,电阻功率 ≈ 0.06 W(建议选用 1/4 W 或更高额定功率)。
    • 以 12 V 电源驱动:若串联 n 个 LED,按总压降计算限流电阻;单颗直接限流需 R = (12 − 2) / 0.02 = 500 Ω。
  • 建议在多数指示应用中采用 10–15 mA 的降额驱动,以延长寿命并降低热量,同时仍能保持良好视觉效果。
  • PWM 调光:支持 PWM 调光,建议 PWM 频率高于 200 Hz 以避免可见闪烁;占空比控制可实现线性亮度调节,但注意低占空比下的驱动电流峰值对热与寿命的影响。

五、热管理与可靠性提示

  • 工作温度范围:-40 ℃ 至 +85 ℃,适合大多数室温与工业环境使用。
  • 为保证长期可靠性,应避免在高温环境中持续满载驱动,必要时采用降额设计(降低 If)或增强散热。
  • PCB 布局建议:为优化散热与焊接强度,控制焊盘尺寸与焊膏量,遵循厂商的 PCB footprint 建议。

六、焊接与存储建议

  • 兼容常见 SMT 回流焊工艺;建议遵循无铅回流焊曲线与制造商的温度与时长规范以降低焊接应力。
  • 存储避免潮湿与强光直射,长期存放建议密封防潮并在规定时间内回流焊接使用。

七、选型与替代考虑

  • 若需要更高亮度或更宽发光角,可考虑封装尺寸更大或使用带扩散/着色透镜的型号。
  • 若追求更长寿命或更高可靠性,可选择在更低电流(例如 5–10 mA)下使用,或选用经过更严格认证的工业等级器件。

总结:APTD3216SYCK(Kingbright,1206/3216)凭借紧凑封装、590 nm 黄色光谱、800 mcd 的可见亮度与 40° 聚焦角度,适合用于需要集中可视提示的小型指示场合。合理的电流与热管理设计将有助于提升其使用寿命与稳定性。如需进一步的机械尺寸图、回流曲线或可靠性数据,请参考 Kingbright 官方规格书或联系供应商获取详细资料。

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.

Replenishment inquiry Typical RFQ workflow
