YLED0805YG 产品概述

一、主要参数概览

YONGYUTAI(永裕泰)YLED0805YG 是一款封装为 0805 的黄绿色发光二极管(LED)。主要参数如下:正向电流 IF = 30 mA(最大);二极管为独立二极管;中心波长 566–576 nm,发光颜色为黄绿色;发光角度 120°;标准发光强度 约 70 mcd;正向压降 Vf 范围 1.8–2.4 V;工作温度范围 -40 ℃ 到 +85 ℃。封装尺寸为 0805(约 2.0 mm × 1.25 mm),适合表面贴装工艺。

二、产品特点

  • 小型表贴封装(0805),适合高密度 PCB 及体积受限场合。
  • 黄绿色波长(566–576 nm),在人眼视觉敏感区域亮度感受好,指示和显示效果清晰。
  • 宽视角 120°,可覆盖较大的观察范围,适用于指示灯和面板灯。
  • 独立二极管设计,便于单点驱动与分区控制,便于故障替换与维修。

三、典型电气与光学特性

  • 最大正向电流:30 mA(建议按应用需求降额使用以延长寿命)。
  • 正向压降:1.8–2.4 V(随电流和温度变化)。
  • 发光强度:≈70 mcd(典型,测量条件下)。
    设计时请以 Vf 范围和最大 IF 为依据计算限流器元件,避免过流。例如,在 5 V 供电、目标电流 20 mA 时:
  • 若取 Vf = 1.8 V,电阻 R = (5 − 1.8) / 0.02 ≈ 160 Ω;
  • 若取 Vf = 2.4 V,R ≈ 130 Ω。
    为避免因 Vf 偏低导致过流,实际选型时应以 Vf 最小值计算以限制最大电流,或采用恒流驱动。

四、封装与安装建议

0805 封装适用于常规回流焊工艺。建议:

  • 遵循 IPC/JEDEC 回流焊温度曲线,峰值温度一般不超过 260 ℃。
  • 贴装与焊接后避免对 LED 发光面施加机械应力。
  • 设计 PCB 焊盘时参考 0805 SMD 元件通用尺寸,并优先参考供应商的推荐焊盘图以获得最佳焊接可靠性。

五、可靠性与环境适应

  • 工作温度范围 -40 ℃ 至 +85 ℃,可满足大多数工业与消费类环境。
  • LED 的寿命与驱动电流、结温和工作环境密切相关;建议在长期使用中对电流和结温进行降额设计以延长寿命。
  • 推荐在生产与维修过程中采用防静电措施(ESD),并在干燥、避免潮湿和污染的条件下存储。

六、典型应用场景

  • 仪器仪表与面板指示灯;
  • 工业控制与信号指示;
  • 消费电子指示(家电、充电器、路由器等);
  • 背光与装饰照明中需要黄绿色提示的场合。

七、选型与驱动建议

  • 若长期可靠性优先,建议将工作电流控制在 10–20 mA 区间而非长期满载 30 mA。
  • 对亮度精度要求高的场合,采用恒流源或带反馈的驱动器优于简单限流电阻。
  • 在多 LED 阵列与高温环境下,应关注结温(Tj)管理与散热设计,必要时降低驱动电流或增加间距。

概括:YLED0805YG 以其小型 0805 封装、黄绿色高可见性发光及宽视角特性,适合各类指示与显示应用。设计时注意电流限流、焊接工艺和温度管理,可在保证亮度的同时提升长期可靠性。若需精确的机械尺寸图、光学曲线或可靠性数据,请咨询供应商获取完整数据手册。

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
