XL-C4040UYC — 4.0×3.95mm 侧面黄光贴片 LED 产品概述
一 概述
XL-C4040UYC 为 Xinglight（成兴光）系列 SMD-4P 小型侧面发光贴片发光二极管，方形封装（约 4.0mm × 3.95mm），采用无色透明透镜，单颗独立二极管设计。典型发光为黄光（峰值 590nm），在点亮、指示和侧面发光照明等应用中表现优秀。
二 主要参数
- 发光颜色：黄色（波长 585nm–595nm，峰值 590nm）
- 正向电压（Vf）：2.0V ~ 2.3V（If = 20mA）
- 额定正向电流：20mA
- 功率：50mW
- 发光强度：900 mcd（典型值，If = 20mA）
- 发光角度：120°（宽视角侧发光）
- 二极管配置：独立二极管
- 透镜：无色透明
- 封装：SMD-4P（4×4 mm）侧面发光封装
- 载带方式：侧贴（便于自动化贴装）
- 工作温度：-20℃ ~ +85℃
三 主要特性
- 侧面发光设计，适合边缘指示、光槽或面板侧照明，视觉均匀性好。
- 宽视角（120°），覆盖范围大，便于低高度均匀照明。
- 小型封装，兼容高速贴片和自动化生产工艺。
- 透明透镜保证色散小、色温稳定，适合指示与标识灯应用。
四 电气与热设计建议
- 常用限流电阻计算：R = (Vcc − Vf) / If。例：Vcc = 5V，取 Vf = 2.1V，If = 20mA ⇒ R ≈ 145Ω，常用 150Ω；Vcc = 12V ⇒ R ≈ 495Ω，常用 500Ω。
- 功率耗散注意：发光功率和芯片自耗会产生热量，PCB 应留足铜箔散热区，避免长时间在高温环境下工作以维持亮度与寿命。
- 频繁脉冲或高占空时需评估平均电流与结温，保持结温在规格范围内以保证可靠性。
五 典型应用场景
- 消费电子的指示灯与面板指示（仪表、家电按钮）。
- 工业设备的状态指示、操控面板背光与光槽引导。
- 仪表、安防设备和显示边缘照明等需要侧向可见性的场合。
六 封装与贴装建议
- SMD-4P 小型方形封装，支持自动贴片（侧贴载带）与回流焊工艺。
- 建议依据厂方推荐的 PCB 贴装孔位与焊盘设计进行布局，保证焊点焊接质量与散热路径。
- 回流焊温度曲线应符合无铅或有铅焊接规范，避免过高峰值温度或过长保温时间。
七 可靠性与工作环境
- 适用工作温度范围 -20℃ ~ +85℃，适合大多数室内与轻工业环境。
- 在高湿、高粉尘或强腐蚀性气氛中使用时建议采取保护措施（密封或涂覆）。
- 建议在设计阶段考虑冗余与降额使用，以延长使用寿命与提高系统可靠性。

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.
