XL-3528UBC（Xinglight 成兴光）产品概述
一、产品简介
XL-3528UBC 是成兴光（Xinglight）推出的一款高性价比蓝色贴片发光二极管，采用SMD3528封装，适合各种通用照明与指示应用。该器件在常见的驱动条件下能提供稳定的蓝光输出，色温集中、发光角度较宽，便于在面板指示、背光和装饰照明等场景中使用。
二、主要参数
- 发光颜色：蓝色
- 峰值波长：465 nm（光谱范围 460–470 nm）
- 正向电压（Vf）：约 3.4 V（典型值）
- 正向电流（If）：20 mA（推荐最大驱动）
- 功率耗散：70 mW
- 发光强度：约 530 mcd（在标准测试条件下）
- 发光角度：120°（无色透明透镜）
- 封装/封装方式：SMD3528 / 载带方式：正贴
- 工作温度范围：-20 ℃ 至 +85 ℃
三、光电特性与封装说明
3528小封装体积紧凑，透明无色透镜保证良好透光性与较宽视角。峰值 465 nm 的蓝光在视觉上显色鲜明，发光强度 530 mcd 在20 mA驱动下满足多数指示和背光亮度需求。因封装小且功率有限，适合用于点光源或小面积阵列，不建议在高功率连续应用中超额驱动。
四、驱动与散热建议
- 推荐恒流驱动，典型驱动电流 20 mA；为延长寿命与稳定输出，可在实际应用中采用 10–15 mA 的去评级驱动策略。
- 根据 Vf≈3.4 V 与 If，选择合适限流电阻或恒流源，避免浪涌电流。
- 虽然单颗功耗仅 70 mW，但在密集贴装或长期开启时需关注PCB散热，建议使用铜箔加厚与散热通道，保证结温在安全范围内。
- 工作温度对光输出和寿命有显著影响，尽量控制环境与结温靠近室温以获得最佳稳定性。
五、典型应用场景
- 面板指示灯、状态指示与信号灯
- 仪器仪表、家电指示窗与按键背光
- 装饰照明、广告标识与小型显示背光
- 低功耗蓝光源需求的电子产品
六、可靠性与存储
- 建议遵循常见的LED存储规范：防潮包装，开封后按回流焊时效要求使用。
- 在超出规定的工作温度或长时间过流驱动下，LED的光通量衰减速度将加快，应在设计阶段留有裕量。
- 出货前通常经过光电参数筛选与电气测试，用户可根据需求申请色容差与亮度分档。
七、使用及选型建议
- 若需更高亮度或更窄发光角，请考虑更大功率或不同透镜设计的封装。
- 在要求长寿命和稳定性的场合，建议采用恒流源并进行热仿真验证。
- 购买时确认色温/波段分档、封装批次和供货包装（卷带方向与贴装兼容性），以保证贴片生产线兼容性。
如需更详细的电气特性曲线、SMD封装尺寸图或建议的PCB焊盘样式，可提供具体资料或样品测试报告以便进一步设计验证。

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.
