YLED1206G 产品概述

一、基本参数与概述

YLED1206G(品牌:YONGYUTAI/永裕泰)是一款1206贴片封装的翠绿色发光二极管(LED)。其面向各种通用照明与显示指示应用,体积小、视角宽、光色稳定。主要基础参数如下:

  • 波长范围:516nm ~ 531nm,峰值波长 525nm(翠绿色)
  • 正向电流:20 mA(典型工作电流)
  • 最大功耗:100 mW
  • 发光强度:620 mcd(典型)
  • 发光角度:120°(广视角)
  • 正向压降 Vf:2.4 V ~ 3.1 V
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:1206 SMD

该型号适合用于面板指示、背光、信号指示和消费电子等需要稳定绿色指示的场合。

二、光电性能

YLED1206G在525nm附近有峰值发射,色调接近翠绿色,肉眼色彩鲜明。发光强度典型值为620 mcd,配合120°的发光角度,能在较大视角范围内提供均匀可见光。光电性能受工作电流与温度影响,增大电流会提高亮度但同时加速老化并升高结温,从而可能导致光输出随温度升高而下降(需做热管理与电流控制)。

三、电气特性与驱动建议

  • 驱动电流:建议以20 mA作为额定驱动电流;若需延长寿命或降低功耗,可采用10–15 mA的降额驱动。
  • 正向压降:2.4–3.1 V 范围,电源与限流元件需按最不利情况(低Vf)考虑以防止过流。
  • 最大功耗:100 mW,实际耗散为 Vf × If。举例:在 Vf≈2.75 V、If=20 mA 时,P≈55 mW,低于标称上限,但仍应注意高温下的功率限制与热堆积。

限流电阻计算(基础公式):R = (Vsupply − Vf) / If 示例(以保证不超过20 mA,按最小 Vf = 2.4 V 计算):

  • Vs = 5 V:R ≥ (5 − 2.4) / 0.02 = 130 Ω(建议取常用值 150 Ω,实际电流约 15 mA)
  • Vs = 12 V:R ≥ (12 − 2.4) / 0.02 = 480 Ω(建议取 560 Ω,实际电流更低以提高安全裕度)

限流电阻功率计算:P_R = I^2 × R。以 130 Ω、20 mA 为例,P_R ≈ 0.052 W(推荐使用 1/4 W 或更高功率等级电阻以提高可靠性与散热裕度)。

四、热管理与可靠性

尽管单个1206 LED散热要求不高,但在高密度封装与长时间点亮场合下要注意结温 (Tj) 的上升。高结温会导致亮度下降、色坐标漂移与寿命缩短。建议:

  • 在PCB布局上预留铜箔散热区域,尽量避免多个高亮LED靠得太近;
  • 在高环境温度(靠近 85 ℃)下应进行电流降额;
  • 遵循厂方的回流焊及储存条件(湿敏等级与翻锡次数),以防潮湿引起焊点与器件问题。

五、封装与安装建议

  • 1206 SMD 尺寸适用于自动贴装与回流焊流程;建议使用标准贴片工艺并控制焊接曲线,避免超出器件耐受的热循环次数与峰值温度。
  • 建议在贴装前做好元件的干燥与防潮处理(若为湿敏器件),并避免在波峰或手工焊接时过度加热LED正面。
  • 设计焊盘时考虑良好的焊盘尺寸与焊膏量,以便获得稳定的焊接强度与热导通。

六、典型应用场景

  • 仪器面板、指示灯、信号指示与状态显示;
  • 消费电子产品指示、遥控器指示;
  • 交通设备、家电面板与机箱指示灯;
  • 需要绿色视觉强调的装饰照明及指引灯带。

七、注意事项与选型要点

  • 在选型时关注亮度(mcd)与波长范围是否满足视觉需求;若要求严格的色容差或一致性,应向供应商索取色温/色区以及分-bin 数据。
  • 电路设计时应优先考虑恒流驱动或合适的限流方案,避免因Vf波动导致过流。
  • 在苛刻环境(高温、高湿或强振动)中使用前,应确认器件的封装可靠性与具体环境试验数据。
  • 如需批量一致性与长期供货保障,建议与 YONGYUTAI 或其授权代理沟通获取长期供货与质量保证信息。

如需进一步的电气曲线(正向特性、光强随电流/温度的曲线)、色度坐标或回流焊工艺规范,可向厂家索取完整数据手册以便精确设计验证。

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.
