LTST-S270GKT 产品概述
一、产品简介
LTST-S270GKT 为 LITEON（台湾光宝）推出的一款黄绿色（Yellow-Green）表面贴装发光二极管（SMD LED）。器件封装紧凑，尺寸为 1.2 x 1.6 mm，透明无色透镜设计，发光角度宽达 130°，适合需要均匀面光或大视角显示的应用。该型号以高可靠性与良好的贴片兼容性见长，适用于各类消费电子、背光指示与信号指示等场景。
二、主要电光参数
- 发光颜色：黄绿色（主波长 565 nm，波长中心 569 nm）
- 正向电压（Vf）：典型 2.1 V（If = 20 mA）
- 最大正向电流（If）：20 mA（推荐驱动电流）
- 最大功率耗散：100 mW
- 发光强度：10 mcd（If = 20 mA，典型）
- 发光角度：130°（大视角）
- 透镜颜色：无色透明透镜
- 工作温度范围：-55 ℃ 至 +85 ℃
- 封装：SMD，尺寸 1.2 x 1.6 mm；载带方式为侧贴（便于自动贴片生产线使用）
三、应用场景
- 面板指示与状态显示（家电、仪器仪表）
- 背光与键盘指示灯
- 信号指示与状态反馈（网络设备、通信设备）
- 需大角度均匀发光的装置与导光结构配合使用
四、设计与驱动建议
- 推荐工作电流 20 mA，以获得标称光强与色点；为延长寿命与降低发热，可在多数应用中采用 5~15 mA 的降流设计。
- 在常温下 Vf 约 2.1 V，设计驱动电阻或恒流源时应考虑工差与温漂。
- 最大功率 100 mW，典型工作时功耗（Vf × If）约 42 mW，仍有余量，但在高密度布局或高环境温度下需注意散热与热集合效应。
- 由于透镜为透明设计，光轴及视角较宽，若需聚光或限制发光方向，应配合遮光罩或微结构光学件。
五、封装与装配注意
- SMD 封装尺寸小，适配常规贴片机与回流焊工艺；载带侧贴方便贴装方向控制。
- 推荐在 PCB 设计时参考厂方推荐焊盘尺寸与焊锡量，避免锡桥或虚焊；留意热循环与回流焊温度对塑封材料的影响。
- 处理与安装过程中注意静电防护（ESD），并遵循生产线的吸湿防护与回流规范以保证成品可靠性。
六、可靠性与储存
- 额定工作温度范围宽（-55 ℃ 至 +85 ℃），适合多数工业与民用环境。
- 建议在实际应用中对环境温度进行降额设计，高温环境下适当降低驱动电流以延长使用寿命。
- 存储与运输中避免潮湿、强光与高温，按厂商包装说明进行干燥箱保存与回流前干燥处理。
七、采购与包装
- 品牌：LITEON（台湾光宝）
- 型号：LTST-S270GKT
- 封装：SMD（带卷带包装，适配自动化贴片）
- 采购时请确认批次与颜色码一致性，并索取产品规格书（Datasheet）以获取焊盘图、回流曲线及全量程电光曲线数据。
如需具体电气特性图、推荐 PCB 焊盘样式或回流焊曲线，可告知，我可以基于官方 Datasheet 帮您整理更详细的工程实施建议。

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.
