XL-3215UBC 1205 蓝色贴片发光二极管 — 产品概述

一、产品简介

XL-3215UBC(1205)是成兴光(Xinglight)推出的一款高可靠性蓝色表面贴装发光二极管。封装尺寸约为3.2 × 1.3 mm(俗称3215/1205封装),采用无色透明透镜、独立二极管结构,发光波长以470 nm为峰值(工作波段460–475 nm),视感鲜明、色纯度高。载带方式为反贴(LED 面朝下),适合自动贴片与回流焊工艺。

二、主要性能参数

  • 封装:SMD,3.2 × 1.3 mm(方形灯头,3.2×1.25 mm 标注)
  • 发光颜色:蓝色
  • 峰值波长:470 nm(光谱范围 460–475 nm)
  • 正向电压(Vf):典型 3.3 V
  • 正向电流(If):最大/标称 20 mA
  • 功率:70 mW
  • 发光强度:约 240 mcd(If = 20 mA,视角 2π/3)
  • 发光角度:120°(宽视角)
  • 二极管配置:独立二极管(单芯片)
  • 透镜颜色:透明无色
  • 工作温度范围:-40 °C 至 +85 °C
  • 载带方式:反贴(flip tape)

三、电、光特性与使用建议

  • 电流与亮度:标称驱动电流为 20 mA,240 mcd 为典型发光强度。为延长寿命和降低温升,设计时常采用 10–15 mA 的降额驱动。
  • 电阻计算示例(单颗、5 V 供电):R = (Vcc − Vf) / If = (5 − 3.3) / 0.02 ≈ 85 Ω,常用 82 Ω 或 100 Ω。
  • PWM 调光:建议使用高频 PWM(>200 Hz)以避免可见闪烁;低占空比下亮度线性下降。
  • 热管理:虽然单颗功耗不大,但在高密度阵列或持续 20 mA 下,需考虑PCB散热与铜箔面积,保证结温在推荐范围内。
  • ESD 与浪涌保护:为防止静电或反向浪涌损伤,生产与装配环节应采取ESD保护;在电路端可并联TVS或串联限流元件。

四、封装与贴装建议

  • 由于载带为反贴(灯面朝下),自动贴装方向与常规贴带略有不同,请在料带上工艺定位。
  • 采用标准回流焊工艺,建议遵循PCB厂家与锡膏供应商的回流曲线(避免超出峰值温度与长期高温暴露)。如长期存放受潮,必要时进行烘烤以防回流过程中发生湿气爆裂。
  • 推荐的PCB焊盘和阻焊开窗请参考3215封装通用封装资料,并根据实际OEM工程图优化焊盘尺寸与焊膏印刷量。

五、可靠性与存储

  • 工作温度宽(-40~+85 °C),适用于室内、户外指示、仪表及一般工业环境。
  • 存储建议:避免高温高湿环境,未开封的推荐在 30 °C / 60% RH 以下保存;开封后若超过推荐时间或潮湿,应进行烘烤处理。
  • 可靠性测试建议:提供寿命测试(HTOL)、温度循环、湿热循环与振动试验,以验证在目标应用环境下的稳定性。

六、典型应用与选型建议

  • 指示灯、面板指示、按键背光、仪表显示、消费电子状态指示等需要较宽发光角度与纯蓝光的场景。
  • 若需更高亮度或严格色品控制,请选择经过波段 / 强度分档(binning)产品,或者联系供应商确认色度与光通量分档信息。
  • 对于汽车或医用等有更高可靠性与认证要求的应用,建议确认是否满足相应资质或选择对应等级件。

七、订购信息与注意事项

  • 型号:XL-3215UBC(1205) 蓝色,品牌:Xinglight(成兴光)。
  • 下单时请确认:封装尺寸、载带方向(反贴)、分档要求(波长 / 强度 bin)、最小包装卷盘数量及生产批次。
  • 使用前请参考供应商提供的完整数据手册(详细的电气参数曲线、光学分布、回流曲线和推荐焊盘),以便在设计中获得最佳性能与可靠性。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
