LTST-C194KRKT 为 LITEON(台湾光宝)生产的红色表面贴装发光二极管(LED),封装为0603(1608 公制)。该器件为透明无色透镜,发光颜色为红色,适用于需要紧凑体积和宽视角的指示、背光及一般显示应用。
封装:0603(1608 公制)微型 SMD,透明透镜利于光学耦合与外观一致性。适用于高密度贴装以及自动化贴片生产工艺。
适用于消费电子指示灯、仪表面板背光、电路板状态指示、遥控器、医疗设备和便携式产品等需要小型、低功耗红光源的场合。
建议驱动电流不超过 20 mA。常见限流电阻计算示例:3.3 V 电源下 R ≈ (3.3−2.0)/0.02 ≈ 65 Ω(可选 68 Ω);5 V 电源下 R ≈ (5−2.0)/0.02 ≈ 150 Ω。功耗约为 Vf×If(例如 2 V×20 mA = 40 mW),仍低于器件最大功率 75 mW,注意整体电路热量分散与焊盘散热设计。
工作温度范围:-30 °C 至 +85 °C。推荐遵循厂商回流焊曲线(一般峰值不超过 260 °C,参照具体数据手册),避免潮湿环境长期存放;取放和贴装时注意静电防护和机械应力,避免重压和侧向拉伸引脚。
选型时参考发光强度、视角及波长要求,若需更高亮度或不同波长,可咨询同系列或相近封装型号。购买时确认包装形式(卷盘/散装)与出厂参数一致,并索取最新数据手册以获得完整规范与焊接参数。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
