SML-D12U8WT86C(ROHM)产品概述

一、产品概述

SML-D12U8WT86C 是 ROHM(罗姆)生产的一款红色发光二极管(LED),封装为 1608(通称 0603)微小贴片型,白色透镜,独立二极管结构。该器件适用于对尺寸和功耗有严格要求的小型指示与显示应用,典型发光波长为 620 nm,呈现标准红色指示光。

二、主要电气与光学参数

  • 发光颜色:红色
  • 峰值波长:620 nm
  • 正向电压 Vf:2.2 V(典型,If = 20 mA)
  • 额定正向电流 If:20 mA
  • 额定功率/耗散:54 mW
  • 发光强度:63 mcd(典型值)
  • 二极管配置:独立二极管
  • 透镜:白色透镜
  • 工作温度范围:-40 ℃ ~ +100 ℃

(注:上述光学参数如发光强度通常以额定正向电流下测得,实际应用中会因驱动电流、封装、透镜及环境温度而有所差异。)

三、机械与封装特性

SML-D12U8WT86C 采用 1608(0603)SMD 封装,体积小巧,便于高密度 PCB 设计与自动化贴装。白色透镜利于光分布均匀与外观一致性。作为小封装器件,焊盘设计与锡量控制对光学一致性与可靠性影响显著,推荐按厂商或通用 SMD LED 建议的焊盘尺寸设计过孔和阻焊。

四、典型应用场景

  • 面板与设备状态指示灯(电源、报警、网络状态)
  • 便携式电子设备与家电指示
  • 小型信号灯与按键指示
  • 医疗仪器、仪表及汽车内饰(限非关键安全用途)
  • IOT 终端与穿戴设备的状态显示

五、使用建议与注意事项

  • 驱动控制:建议恒流驱动或在串联限流电阻(见示例计算)下工作,避免直接并联接入恒压电源。
  • 热管理:尽管功耗不大,但在高温环境或高密度布局中应注意散热与电流降额,以保证长期可靠性。
  • 焊接与工艺:兼容常规回流焊工艺,建议遵循焊接曲线与回流峰值温度限制,避免长时间超温。
  • 防静电:LED 对静电敏感,搬运装配时应采取 ESD 防护措施。
  • 储存与搬运:避免潮湿与污染,贴片后尽量缩短暴露时间并遵循厂商防潮建议。

六、示例电路与限流计算

常见用法是在电源与 LED 之间串接限流电阻 R:

  • 3.3 V 电源:R = (3.3 V − 2.2 V) / 0.02 A = 55 Ω → 选用 56 Ω;电阻功耗 P = I^2·R ≈ 0.02^2·56 ≈ 0.0224 W。
  • 5 V 电源:R = (5 V − 2.2 V) / 0.02 A = 140 Ω → 可选 150 Ω;电阻功耗 ≈ 0.06 W。
    以上计算基于典型 Vf = 2.2 V,实际设计时应考虑 Vf 的公差、工作温度及寿命要求,可适当增大限流电阻或降低驱动电流以提高可靠性与寿命。

七、结论

SML-D12U8WT86C 为一款适用于空间受限场合的小型红色 SMD 指示 LED,具有稳定的光学特性与适中的发光强度。通过恰当的驱动、焊接工艺与热管理,可在消费电子、仪器仪表及各种指示场景中获得良好表现。如需更详细的封装图、回流曲线或光学分布图,请参阅 ROHM 官方产品规格书或联系供应商获取完整数据手册。

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.

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
