LTST-S220KSKT 产品概述
LTST-S220KSKT 是来自台湾光宝（LITEON）的小尺寸黄色贴片发光二极管，采用 SMD 1.0×2.2mm 封装，面向空间受限的状态指示与背光应用。该器件以清晰无色透镜、宽视角和稳定的光电参数，适用于消费电子、仪表面板、按键指示与车载非关键指示灯等。
一、主要技术参数
- 发光颜色：黄色
- 正向压降 (Vf)：约 2.0 V
- 额定正向电流 (If)：20 mA（典型工作点）
- 最大耗散功率：75 mW
- 峰值波长：591 nm；标称波长：589 nm
- 发光强度：54 mcd（If = 20 mA 时的典型值）
- 发光角度：130°（宽视角）
- 透镜颜色：无色透明
- 封装形式：SMD，尺寸 1.0 × 2.2 mm
- 载带方式：侧贴（side-feed）
- 工作温度范围：-30 ℃ ~ +85 ℃
二、产品特点
- 小尺寸 SMD 封装，便于高密度 PCB 布局与微型化设计。
- 宽视角 130° 提供均匀的视觉覆盖，适合指示与面板照明。
- 清晰无色透镜确保发光色纯净，色点集中，利于色彩一致性控制。
- 低正向压降与中等光强，在低功耗场景下表现稳定。
- 侧贴载带方式利于自动贴装线取料与方向控制，提高生产效率。
三、典型应用
- 消费类电子状态指示（电源、充电、网络指示等）
- 仪表面板与按键背光
- 小型显示模块与信号指示灯
- 家电与工业控制面板的视觉提示
四、设计与使用建议
- 串联限流电阻计算示例（以 5 V 电源为例）：R = (VCC − Vf) / If ≈ (5 V − 2 V) / 20 mA = 150 Ω，取标准阻值并考虑元件容差与温升。
- 由于最大耗散功率为 75 mW，推荐在长期使用时对电流适当降额（如 ≤ 20 mA）并注意结温控制，避免长期在高温环境中满载工作。
- 对于需要严格色温或亮度一致性的应用，建议在同一批次中选型并进行排序（binning）校正。
- PCB 布局时在发光面附近保留适当开窗和遮光结构，以避免光学串扰和提高可见性。
五、焊接与可靠性提示
- 推荐采用贴片回流焊工艺，遵循无铅/含铅回流曲线规范，避免长时间在高温区停留以防封装变形。
- 储存与搬运注意防潮与防静电（ESD），在 SMT 前采用规定的烘烤流程去除潮气。
- 工作温度范围 -30 ℃ ~ +85 ℃，在极端低温或高温环境下需进行可靠性验证。
六、选购与包装信息
- 品牌：LITEON（台湾光宝）
- 产品型号：LTST-S220KSKT
- 封装：SMD 1×2.2 mm，载带侧贴包装，适配自动贴片机取料。
- 选购时请确认所需电流、亮度等级（mcd bin）与色度 bin，确保与系统要求匹配。

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.
