LTW-C193SN5（0603）产品概述
一、产品简介
LTW-C193SN5 是台湾光宝（LITEON）出品的一款贴片发光二极管，封装尺寸为0603（约1.6×0.8 mm），采用独立二极管结构与黄色透镜设计，发出白色光。该器件针对微型指示与点状背光应用优化，具有宽广的视角与良好的光学均匀性，适合空间受限的电子产品。
二、主要规格参数
- 发光颜色：白色（黄透镜）
- 正向电流：5 mA（典型驱动）
- 正向压降 Vf：2.65 V ～ 3.15 V
- 功率：35 mW（最大）
- 发光强度：146 mcd（在5 mA时典型）
- 发光角度：130°（广视角）
- 工作温度：-20 ℃ ～ +80 ℃
- 二极管配置：独立二极管
- 封装：0603（SMD）
三、电气与光学应用建议
- 驱动方式：建议使用恒流源驱动，典型电流为5 mA，以保证稳定亮度与长寿命。若使用限流电阻，计算公式为 R = (Vsupply - Vf) / If。
示例：5 V 电源且按最大可能 Vf=2.65 V 计算以防止过流，R ≈ (5 − 2.65) / 0.005 ≈ 470 Ω（取标准值470 Ω）；若电源为12 V，则 R ≈ (12 − 2.65) / 0.005 ≈ 1.87 kΩ（可取1.8 kΩ或2 kΩ并考虑功率裕度）。 - 功率与发热：在5 mA 工作点，器件耗散功率远低于35 mW 最大值，但仍需注意PCB热路径及相邻元件散热，避免长期高温影响光输出与寿命。
- 光学特性：黄色透镜结合白色芯片有助于改善光学均匀与出光扩散，130°大视角适合指示与面光源用途，典型亮度146 mcd 在显示/指示场景表现良好。
四、封装与焊接注意
- 0603 小型封装，适用于高速贴装与回流焊流程。推荐参照光宝的数据表提供的推荐PCB焊盘尺寸与回流曲线进行焊接。
- 采取标准回流焊工艺并控制峰值温度与时间，避免超出供应商建议以免影响发光效率或封装老化。
- 处理时注意防静电（ESD）保护与防潮包装，未使用器件建议保持原厂干燥包装以防吸湿现象。
五、典型应用与可靠性要点
- 典型应用：消费电子指示灯、仪表面板、手持设备状态指示、白光点状背光与嵌入式照明。
- 可靠性：在指定工作温度范围（-20 ～ +80 ℃）内使用可获得稳定性能。长期高温、高湿或超额流条件会加速光衰与寿命下降，设计时应留有裕量并遵循光宝的可靠性与存储说明。
- 其它注意：如需精准色度、光通量或长期光衰数据，请参阅原厂完整技术规格书并在量产前进行样件验证。
如需我帮您计算不同电源或并联/串联方案下的限流元件选型、PCB焊盘推荐或给出按批量采购的注意事项，可继续提供电源、电路与环境条件，我将给出更具体的设计建议。

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.
