YLED0402B 产品概述

一、产品简介

YLED0402B 是永裕泰(YONGYUTAI)推出的一款超小型蓝光贴片发光二极管(0402 封装),外形尺寸仅 1.1 × 0.5 × 0.4 mm,采用透明平面胶体与无色透明透镜,单颗为独立二极管结构。该器件在技术参数、封装兼容性与环保要求方面均满足现代电子产品对高密度组装和回流制程的需求,适用于各种要求体积小、响应快的标示与背光应用。

二、主要规格参数

  • 发光颜色:蓝色
  • 波长范围:460 nm ~ 475 nm,峰值波长 469 nm
  • 正向电压 Vf:2.6 V ~ 3.1 V
  • 额定正向电流 If:20 mA
  • 功率:100 mW
  • 发光强度:100 mcd(典型)
  • 发光角度:120°
  • 二极管配置:独立二极管
  • 透镜:无色透明平面胶体
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:0402(EIA STD Package)
  • 外观尺寸:1.1 × 0.5 × 0.4 mm
  • 环保:RoHS 合规
  • 品牌:YONGYUTAI(永裕泰)

三、光电特性与电气设计建议

  • 由于 Vf 在 2.6~3.1 V 范围内波动,电路设计时应考虑最大和最小 Vf 对电流的影响。
  • 推荐工作电流:典型 20 mA;若需要降低亮度或延长使用寿命,可采用 5–10 mA 的欠流驱动。
  • 串联电阻计算示例(以 5 V 电源、目标电流 20 mA 为例):R = (VCC − Vf) / If ≈ (5 V − 2.8 V) / 0.02 A ≈ 110 Ω(取常用阻值 120 Ω)。
  • 对于多颗并联驱动,应使用每颗一只限流电阻以保证亮度一致性及可靠性。

四、封装与制造兼容性

  • 0402 超小封装完全兼容自动贴片机(SMT)及 EIA 标准封装要求,适用于高密度 PCB 设计。
  • 支持红外线回流焊制程;建议参考回流曲线,峰值温度与时间应符合焊料和 SMT 组件的规范(一般峰值 ≤ 260 ℃,精确参数请遵循厂方回流曲线)。
  • 建议在 PCB 设计阶段采用厂方或 EIA 推荐的 0402 焊盘尺寸以保证贴装良率。

五、典型应用

  • 状态指示灯、面板指示、按键背光
  • 可穿戴设备与微型电子产品指示元件
  • 物联网终端、遥控器、消费电子及微型显示辅助照明
  • 车载信息指示(在相应温度与认证范围内)

六、使用与焊接注意事项

  • 建议干燥保存,避免潮湿环境。开封后若长时间暴露在空气中,可能需要按厂家建议进行预烘烤以去除吸湿。
  • 贴装与回流焊时注意温度曲线与时间窗,避免超出材料承受范围。
  • 操作过程中做好静电防护(ESD),以保护二极管免受损坏。
  • 存储于原厂防潮包装,避免强光直射与高温环境。

七、环保与质量保证

  • 产品符合 RoHS 环保要求,采用无铅可回收材料及环保包装,满足现代电子产品环保合规性需求。
  • 封装与标称参数经过工厂测试与出货检验,适用于自动化批量生产。
  • 如需完整的电气、光学曲线、回流曲线和封装尺寸图(PCB 推荐焊盘),建议联系永裕泰技术支持获取详细数据手册与验证样品。

YLED0402B 以其极小的体积、稳定的蓝光输出与良好的封装兼容性,适合对体积和自动化装配有严格要求的电子产品设计与量产场景。若需样品或批量报价,请提供需求数量与应用环境以便进一步支持。

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
