一、产品核心定位与典型应用场景
该型号属于永铭贴片铝电解电容系列的主力规格，聚焦中高压（50V）、大容量（470uF） 场景，主要解决电路纹波抑制、瞬时能量补充问题。典型应用包括：
- 工业电源模块：作为输出滤波电容，降低电压纹波，提升电源稳定性；
- 消费电子主板：适配电脑、电视等设备的电源电路，满足高密度布局需求；
- 车载电子：支持车载中控、照明系统等宽温环境下的稳定工作；
- 音频设备：用于功放电路滤波，减少噪声干扰，提升音质表现。
二、关键电气性能参数详解
产品电气参数经过严格校准，核心指标清晰可靠：
- 容值与精度：标称容值470uF，精度±20%——满足大部分滤波电路对容量的需求，无需额外高精度校准；
- 额定电压：50V直流耐压——适配12V/24V系统的升压模块等中高压场景，避免过压损坏；
- 温度特性：工作温度范围-55℃~+105℃——覆盖极端环境（北方低温、设备内部高温），可靠性更高；
- 工作寿命：10000小时@105℃——高温持续工作场景（如LED驱动、逆变器）下，寿命优于普通规格，降低维护频率。
三、物理结构与封装特性
采用贴片式（SMD）封装，物理尺寸紧凑且适配自动化生产：
- 尺寸规格：电容体直径12.5mm、长度14.5mm——符合贴片元件贴装标准，适配常规PCB布局；
- 封装设计：径向引线贴片结构，焊接可靠性高，抗振动性能优于插件电容，适合移动或工业振动环境；
- 空间优势：同容量同耐压下，尺寸属于紧凑级别，可有效节省PCB空间，支持设备小型化设计。
四、环境适应性与可靠性验证
产品通过多项可靠性测试，确保恶劣环境下稳定工作：
- 高低温循环：-55℃~+105℃循环1000次，容值变化率≤±10%，符合工业级要求；
- 耐振动测试：支持10~2000Hz振动频率、1.5g加速度，满足车载及工业设备振动环境；
- 寿命衰减：105℃额定电压下工作10000小时，漏电流≤初始值150%，性能可控。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
