LTST-C281KGKT 产品概述
一、产品简介
LTST-C281KGKT 是 LITEON（台湾光宝）推出的一款黄绿色（Yellow-Green）LED 芯片光源，采用无色透明透镜设计，光学性能稳定，适合各种指示与光源应用。该器件在典型驱动条件下具有良好的发光强度与宽视角，兼顾亮度与可视性。
二、主要电光参数
- 发光颜色：黄绿色（Yellow-Green）
- 峰值波长（λp）：574 nm
- 波长（主波长）：571 nm
- 正向电流（IF）：20 mA（额定/推荐工作电流）
- 正向压降（Vf）：约 2.0 V（典型值）
- 功率耗散：75 mW（最大功率）
- 发光强度：35 mcd（典型值，测量条件通常为 IF=20 mA）
- 发光角度：130°（半功率角，视场宽广）
- 工作温度范围：-30 ℃ ~ +85 ℃
- 透镜颜色：无色透明透镜
- 封装：Chip（详见厂商数据手册获取外形尺寸与焊盘信息）
（注：以上典型值与测量条件通常基于 IF=20 mA、Ta=25 ℃，具体参数请以厂方数据手册为准。）
三、应用场景
- 面板指示灯、仪表指示
- 消费类电子产品状态指示（家电、遥控器等）
- 工业控制与信号灯
- 小型显示与装饰照明点缀
其宽视角（130°）与清晰的黄绿色光色使其在需要良好侧向可见度的场合表现良好。
四、使用与电路建议
- 推荐稳定电流驱动，避免直接接入恒压电源。
- 常用电阻计算（以 5 V 电源为例）：R = (VCC - Vf) / IF = (5 V - 2 V) / 20 mA ≈ 150 Ω（取常规阻值 150 Ω 或 160 Ω，按功率选型）。
- 不要超过额定正向电流 20 mA 与功率耗散 75 mW，长期超额会降低寿命与光输出。
五、热与可靠性注意事项
- 工作温度范围为 -30 ℃ 至 +85 ℃，在高温环境下需考虑适当降额使用以延长寿命。
- 芯片类 LED 对焊接、回流曲线与PCB热阻敏感，推荐参考厂商的焊接与回流规范。
- 储存与装配时注意防潮与静电保护（ESD），以避免损伤。
六、封装与选型建议
封装标注为 Chip，外形与焊盘详情请参照 LITEON 官方数据手册或供应商提供的 3D/2D 图纸。选型时同时确认光强等级、颜色一致性（Bin）与出货批次的稳定性，以满足批量一致性需求。
七、总结
LTST-C281KGKT 是一款适用于多种指示与小型照明场景的黄绿色 LED 芯片，具有较低工作电压（≈2.0 V）、标准 20 mA 驱动电流和 130° 宽视角。良好的发光强度与宽温范围使其在消费电子与工业指示应用中可靠性高。欲获得完整性能参数与封装细节，请参考 LITEON 官方数据手册或联系授权经销商。

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.
