RVT2A470M1010 产品概述

一、产品简介

RVT2A470M1010 为 ROQANG(容强)出品的贴片铝电解电容,标称电容值 47μF,公差 ±20%,额定电压 100V。封装为 SMD 形式,电容体直径 10mm、长度 10.2mm(D10×L10.2mm),适用于空间受限且需较高工作电压的电源滤波与能量储存场合。额定工作温度范围为 -40℃ 至 +105℃,在 105℃ 下的寿命为 2000 小时。

二、关键电气与机械参数

  • 电容值:47μF ±20%
  • 额定电压:100V(极性电容,注意正负极)
  • 纹波电流:148mA @ 120Hz
  • 工作温度:-40℃ ~ +105℃
  • 寿命:2000 小时 @ 105℃
  • 封装/尺寸:SMD,电容体直径 10mm,长度 10.2mm 这些参数决定了器件适用于中低频纹波滤波与直流母线储能,但在高纹波或高频大电流场合需注意散热与并联方案。

三、性能特点与优势

  • 高耐压:100V 额定电压适合较高电压的直流回路,如工业电源、功率放大器电源滤波等。
  • 紧凑体积:D10×L10.2mm 的 SMD 体积便于自动贴装,适合密集 PCB 布局。
  • 宽温区与高温寿命:-40~+105℃ 的范围适应广泛环境,105℃ 下 2000h 的寿命可满足一般工业级应用要求。
  • 易于加工与装配:SMD 封装支持回流焊和自动化贴装,提高生产效率。

四、应用场景

  • 开关电源与线性电源的输出滤波
  • 高频直流链路的储能与去耦(需关注频率与纹波能力)
  • 工业控制设备、电机驱动以及通信设备的电压稳定与滤波
  • 需要较高耐压但尺寸受限的电源模块

五、选型与使用建议

  • 纹波管理:本型号 148mA@120Hz 的纹波能力偏向中小功率直流滤波;在高频开关电源中,应注意频率对容器内阻(ESR)与发热的影响,必要时并联低 ESR 的固态电容或增加并联电解电容以提高纹波处理能力。
  • 电压与温度降额:为延长寿命,建议在实际设计中对额定电压进行适当降额(例如 ≤80%)并尽量降低工作温度;高温与高电压会显著缩短使用寿命。
  • 极性与焊接:为极性电容,装配时必须标注并确认极性方向;遵循元件厂商的回流焊工艺建议,避免长时间高温或过度机械应力。
  • 储存与老化:长时间存放前应按厂家建议保持干燥,必要时在回流前进行烘烤以防吸湿引起焊接缺陷或电容失效。

六、可靠性与维护要点

  • 在高温(接近 105℃)或连续大纹波工作下,电解液老化会加速,应在设计时预留维护和更换周期。
  • 对关键应用建议进行温升与寿命评估仿真,根据实际 PCB 散热条件选择合适的降额系数或并联冗余。
  • 生产过程中保证正确的贴装方向和焊接参数,避免机械应力导致外壳裂纹或内部损伤。

综上,RVT2A470M1010 是一款面向中等能量储存与中小纹波滤波的高压 SMD 铝电解电容,适合在体积受限且需 100V 级别耐压的电源与工业电子场景中使用。选型时重点考虑纹波需求、温度环境与寿命降额,以确保长期可靠运行。

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
