LTST-C930KSKT — 黄色透明 1210 封装 LED 产品概述

一、产品简介

LTST-C930KSKT 是 LITEON(光宝)推出的一款黄色(YELLOW)高亮度表面贴装 LED,采用 1210(约 3.2 mm × 2.5 mm)封装,透明无色透镜、窄光束设计,适合需要高指向性和明显视觉提示的指示与光源应用。该器件在标准驱动电流下表现出稳定的亮度与色温一致性,工作温度范围宽,适应工业级使用环境。

二、主要规格(典型/额定值)

  • 发光颜色:黄色
  • 峰值波长:588 nm
  • 波长范围:587 nm ~ 594.5 nm
  • 正向电压 (Vf):约 2.0 V(在 If = 20 mA)
  • 正向电流 (If):20 mA(额定驱动电流)
  • 功率:75 mW(器件允许的最大耗散功率)
  • 发光强度:800 mcd(在标准测试条件,If = 20 mA)
  • 发光角度:25°(典型半角,窄光束)
  • 透镜颜色:透明无色(Clear)
  • 封装尺寸:1210(约 3.2 mm × 2.5 mm)
  • 工作温度:-55 ℃ ~ +85 ℃

三、光学与电气特性解析

  • 波长与颜色:588 nm 的峰值波长位于典型黄色光谱中心,视觉亮度感强,适合信号指示与高对比度显示。给定的波长容差(587–594.5 nm)保证了在批次间色差可控。
  • 发光强度与角度:800 mcd 的亮度配合 25° 的小发散角,呈现明显的聚光性,适合面向观察者的指示灯设计或需要远距离可见性的场合。透明透镜有利于光束整形并保持较高的轴向亮度。
  • 电气耗散:在 If = 20 mA、Vf ≈ 2.0 V 时,电气耗散约为 40 mW,明显低于器件最大功率 75 mW,因此在规范驱动下有一定安全裕度。但不建议超额驱动以追求更高亮度,应遵循制造商的额定 If 及热管理要求。

四、封装与安装建议

  • PCB 尺寸与焊盘:推荐按照 1210 标准封装的 PCB 焊盘设计,保证焊盘面积和焊膏量匹配,以获得良好热传导与焊点可靠性。
  • 光轴与开孔:由于 25° 的窄光束特性,应在面板开孔或光学孔对齐 LED 光轴,避免遮挡并尽量减少漫射层以保持亮度。
  • 回流焊注意:遵循供应商的焊接曲线与 PCB 材料规范,避免过高的峰值温度与过长的热暴露时间,以防封装或内部光学材料劣化。

五、驱动与热管理

  • 驱动方式:推荐使用恒流驱动或在串联限流电阻的恒压驱动下工作,确保电流稳定于 20 mA 上限之内。避免直接并联多个 LED 而无均流措施。
  • 热管理:尽管在 20 mA 时功耗较低,但在高密度布板或高环境温度时应考虑散热通道或增加铜箔面积以降低结温,延长寿命并维持光输出稳定性。
  • 浪涌与瞬态:上电浪涌电流可能对 LED 造成冲击,建议在驱动电路中加入软启动或限流保护元件,避免短时间内超过器件额定电流。

六、环境与可靠性

  • 工作温度范围宽(-55 ℃ 至 +85 ℃),适合大多数工业与商业环境。
  • 在潮湿或腐蚀性环境中使用时,应采取防潮、防盐雾的封装或表面处理措施,避免焊点与端子腐蚀影响可靠性。
  • 存储与搬运:建议按湿敏等级(MSL)要求保存,避免长时间暴露在高湿环境下,贴片前若超过吸湿时限应按回流前烘烤要求回烘。

七、典型应用场景

  • 面板/指示灯:工业设备、仪器面板、控制台的状态指示。
  • 消费电子:家电指示、手持设备状态灯。
  • 商业标识与信号:需要定向发光的标识、指示箭头或信号装置。
  • 工业控制:在环境温度要求较高的应用中作为可靠的视觉反馈组件。

八、注意事项与采购建议

  • 请以厂商正式数据手册(Datasheet)为最终依据,特别是在焊接、热规和可靠性试验条件下的具体参数。
  • 选购时注意光通量/发光强度分档(Binning)与色偏分档,若系统需色彩一致性,应在同一色况分档中下单。
  • 如需用于汽车或安全关键系统,请确认是否有相应认证与长期可靠性测试数据。
  • 若对亮度、色点或安装有特殊要求,建议向供应商索取样品并在目标应用环境下进行评估验证。

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
