YLED0805O 产品概述
一、产品简介
YLED0805O 是永裕泰（YONGYUTAI）推出的一款0805（2012英制）封装橙色贴片发光二极管（LED）。单体二极管设计、视角宽（120°），在-40℃+85℃工作温度范围内稳定工作，适用于多种指示、背光及信号显示场合。典型峰值波长600nm612nm，呈现饱和橙色光效。
二、主要参数
- 发光颜色：橙色
- 峰值波长：600 nm ~ 612 nm
- 正向电压（Vf）：1.8 V ~ 2.4 V
- 额定正向电流：25 mA（最大/额定）
- 发光强度：144 mcd（规格值，按额定电流测定）
- 发光角度：120°（半强度角）
- 封装：0805 SMT（独立二极管）
- 工作温度：-40℃ ~ +85℃
三、封装与机械建议
0805体积小、适合高密度贴装。推荐采用标准0805焊盘尺寸并遵循厂家推荐的PCB焊盘与回流焊工艺，保证焊点可靠性。对高密度布局建议加大焊盘下方铜皮或引入热通孔以利散热，避免多颗高电流LED长期连续发光导致温升过高。
四、电气设计与电阻选择
LED为恒流器件，应串联限流电阻或采用恒流驱动：
- 阻值计算公式：R = (Vs - Vf) / I 举例（取If = 25 mA）：
- 3.3 V 电源：R ≈ (3.3–1.8)/0.025 = 60 Ω（Vf=1.8）至 36 Ω（Vf=2.4）
- 5.0 V 电源：R ≈ 128 Ω（Vf=1.8）至 104 Ω（Vf=2.4）
电阻耗散功率 P = (Vs - Vf) × I，5 V/25 mA 最大约 0.08 W，建议采用 1/8 W ~ 1/4 W 安规电阻以保证余量。为延长寿命与降低发热，可考虑将驱动电流降低至 10–20 mA。
五、应用场景
适合做为各类状态指示灯、面板指示、家电与仪器仪表指示、手持设备与物联网终端指示、按键背光或装饰性光源。因封装小巧，也适用于空间受限的消费电子产品与工业控制面板。
六、可靠性与使用注意
- 避免在超出额定电流/温度下长期工作，长期高温会导致亮度衰减与寿命缩短。
- LED 对静电敏感，生产与装配应采取ESD保护措施（佩戴防静电手环、使用导电包装等）。
- 建议按照标准回流焊曲线进行焊接，避免重复高温暴露。
- 若需车规级或更严格环境应用，请与厂商确认额外认证与性能保证。
YLED0805O 以小尺寸、稳定发光与较高亮度适配多种指示应用，设计时注意限流与散热即可获得可靠长期的光学表现。欢迎在具体应用中提供电源与布板信息，可进一步给出更精确的驱动与布局建议。

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.
