RVT1V4R7M0405 产品概述
一、产品简介
RVT1V4R7M0405 为 ROQANG（容强）推出的贴片型铝电解电容，额定电容值 4.7µF，容差 ±20%，额定电压 35V。外形为 SMD 小型圆柱体，电容体直径 4mm、长度 5.4mm（封装标识 D4×L5.4mm），适合高密度贴片装配场景。
二、主要参数
- 容值：4.7µF（±20%）
- 额定电压：35V
- 纹波电流：15 mA @120Hz
- 体积：直径 4mm × 长度 5.4mm（SMD）
- 工作温度：-40℃ ~ +105℃
- 工作寿命：2000 小时 @105℃
三、性能与可靠性
本型号为铝电解结构，适用于要求中等容值与较小尺寸的电源滤波与旁路场合。2000 小时 @105℃ 的寿命指标表明在高温应力下具备一定耐久性，但在长期或高纹波工况下需注意寿命衰减。额定纹波电流较小，适合低功率、低纹波应用；若用于高纹波或高频开关电源，应复核实际纹波损耗与温升。
四、典型应用场景
- 消费类电子中低功耗电源滤波与去耦
- 仪表与控制板的平滑电容与旁路电容
- 小体积 DC-DC 调节器输出滤波（需确认纹波与温升）
- 音频前端滤波和耦合（注意极性和漏电流要求）
五、封装与安装建议
该器件为贴片封装，推荐使用标准回流焊工艺安装。为保证可靠性：
- 注意极性标识，避免反向安装；
- 回流焊温度曲线请参照厂商推荐，避免超出焊接峰值时间和温度；
- 在长期存放或受潮后，必要时进行预烘烤以防焊接缺陷；
- 布局上尽量靠近电源引脚并提供充分散热路径，以降低工作温度并延长寿命。
六、选型与订购建议
在选型时除电容值与电压外，应重点核实实际纹波电流、ESR、漏电流及工作温度下的寿命要求。若系统存在较高纹波或需要更长寿命，建议选择更大纹波电流等级或寿命更长的型号。订购时参考型号 RVT1V4R0405（或厂商给出的完整料号）并向供应商确认可用的批次与出货规格单。

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.
