NCD1803Y1 产品概述

NCD1803Y1 是国星光电推出的一款高性价比小型贴片发光二极管(LED),封装尺寸为 SMD 1.0 × 1.8 mm,侧贴载带方式,适用于紧凑型面板指示、仪表显示、消费电子和物联网终端等对体积、功耗和视角有综合要求的应用场景。该器件在黄色/琥珀波段具有良好的发光效率与宽视角特性,可在较宽温度范围内稳定工作。

一、主要规格亮点

  • 正向压降(Vf):约 2.0 V(典型值)
  • 额定功率:65 mW(最大耗散能力)
  • 额定正向电流:25 mA(最大工作电流)
  • 峰值波长:592 nm;基波长:589 nm(黄/琥珀波段)
  • 发光强度:30 mcd(典型)
  • 发光角度:145°(宽视角,适合指示和均匀照明)
  • 封装形式:SMD,尺寸 1 × 1.8 mm,侧贴(便于某些贴装方向和光路设计)
  • 工作温度范围:-30 ℃ ~ +85 ℃

二、光电性能与应用建议

NCD1803Y1 的峰值波长与基波长位于 589–592 nm,发光颜色偏黄色/琥珀。发光强度典型值为 30 mcd,配合 145°的大视角,可在较宽的观察区域内提供稳定的视觉指示效果,适合以下应用:

  • 面板指示灯、状态指示、开关指示
  • 家用电器与办公设备的信号提示
  • 仪表与工业控制面板(在指定温度范围内)
  • 可穿戴设备与小型移动终端的微型指示灯
  • 背光或点光源应用(需评估亮度是否满足)

注意:具体亮度与色点受驱动电流、封装散热和测试条件影响,设计时应参考厂方数据手册以及在目标系统中进行实际测量。

三、电气设计与驱动建议

  • 恒流驱动优先:建议使用恒流驱动器或在限流电阻的前提下工作,以避免电流过大导致寿命或亮度不稳定。
  • 限流电阻示例计算(以 Vf = 2.0 V 为估算):
    • 供电 5 V,目标 If = 25 mA:R = (5 − 2.0) / 0.025 = 120 Ω;耗散功率约 50 mW(P = Vf × If = 2.0 × 0.025 = 50 mW)
    • 供电 3.3 V,目标 If = 20 mA:R = (3.3 − 2.0) / 0.020 = 65 Ω;耗散约 40 mW
  • 功率裕量:器件最大额定功率 65 mW,实际耗散(Vf × If)应控制在该值之下并留有裕度,以提高可靠性与寿命。
  • PWM 调光:可用 PWM 控制亮度,但建议频率足够高以避免可见闪烁并注意瞬态电流限制。

四、封装与贴装注意事项

  • SMD 1×1.8 mm 小体积,可实现高密度贴装。侧贴(side-feed)方式在特定的 PCB 布局和指示方向上具有优势。
  • 建议遵循国星光电的推荐 PCB 焊盘尺寸与回流焊曲线。避免过高的回流温度和长时间高温暴露,以防封装变形或内焊点老化。
  • 对于潮湿敏感度(MSL)与回流焊前的烘干处理,请参照厂家包装标签与出厂说明执行。

五、可靠性与环境条件

  • 工作温度范围为 -30 ℃ 至 +85 ℃,适合大多数民用与部分工业使用环境。若需用于更严苛的温度或振动环境,请与供应商确认额外的可靠性测试数据。
  • 建议在防静电环境中操作(ESD 防护),并在制造与维护过程中采取相应的静电防护措施。
  • 存储时避免高温高湿、强光直射与化学蒸汽,必要时采取防潮包装。

六、检验与选型参考

  • 在选型过程中,除上述典型参数外,建议索取并参考完整的数据手册(IV 曲线、光强-电流曲线、不同温度下的光学特性、封装尺寸图及回流焊建议曲线等)。
  • 在样机阶段做实际测量(亮度、波长、视角、功耗与热耦合影响),并在目标应用环境下测试长期可靠性和一致性。

总结:NCD1803Y1 是一款体积小、视角宽、黄色/琥珀发光的 SMD 指示型 LED,适合空间受限且对视觉覆盖要求较高的应用。合理的驱动与热管理能确保其在 -30 ℃ 至 +85 ℃ 温区内长期稳定工作。若需更详尽的电绝、光学曲线或封装资料,请联系国星光电或索取该型号完整技术手册。

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.

Replenishment inquiry Typical RFQ workflow
