RVT1E221M0810 产品概述

RVT1E221M0810 是 ROQANG(容强)推出的一款贴片型铝电解电容,额定容量 220µF、额定电压 25V,体积小巧(Φ8mm × L10.2mm),专为对体积、寿命和中等纹波要求的便携式与嵌入式电源应用设计。

一、主要规格

  • 容值:220µF(±20%)
  • 额定电压:25V
  • 纹波电流:183mA @ 120Hz
  • 外形尺寸:φ8mm × L10.2mm(SMD)
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 小时 @ 105℃
  • 封装形式:贴片(SMD)

二、产品特性

  • 小尺寸、高容值:8mm×10.2mm 的紧凑封装在有限空间内提供 220µF 的滤波与旁路能力,适合紧凑型电路板设计。
  • 中等纹波能力:183mA @ 120Hz 的纹波电流适用于低功率开关电源与线性稳压器的输入/输出滤波。
  • 宽温度范围与长寿命:-40℃ 至 +105℃ 的工作温度和 2000 小时的高温寿命,适合工业级与散热受控的消费类电子产品。

三、电气性能说明

  • 容值公差 ±20%,在选型时请考虑容值随温度和老化的变化,并按电路容错需求预留裕量。
  • 纹波电流参数按 120Hz 标准测得,若工作在高频开关电源环境,应结合频率特性与等效串联电阻(ESR)评估实际热升及寿命。若需 ESR、阻抗随频率/温度曲线,请参照完整数据手册或向厂方索取测试资料。

四、外形与封装

  • 贴片式铝电解电容,底部为焊盘式接触,便于自动贴装与回流焊工艺。
  • 在 PCB 布局时,应为贴片电容预留足够的焊盘尺寸与焊膏量,保证良好焊接可靠性与散热路径。

五、典型应用场景

  • 开关电源输入/输出滤波与稳压器旁路
  • 手持设备、便携终端的去耦与能量缓冲
  • 工业控制电源、通信设备的辅助滤波
  • 音频前端的电源滤波(需结合 ESR/噪声要求评估)

六、可靠性与寿命

  • 在 105℃ 环境下额定寿命为 2000 小时;在更低工作温度下寿命会显著延长。长期可靠性受温度、纹波电流和应用环境影响,设计时建议按温升与寿命衰减进行裕度计算。
  • 为获得更准确的寿命预测,应结合实际工作电压与工作温度曲线使用厂方的寿命模型或加速老化试验数据。

七、PCB 布局与焊接注意事项

  • 建议采用推荐的焊盘布局与焊膏印刷量,避免因焊点过多或过少导致焊接缺陷。
  • 贴装后应采用适当的回流焊工艺,避免过度热冲击。具体回流温度曲线请遵循厂方资料;若使用潮湿敏感器件管理(MSL),请遵守烘箱烘干与回流前的防潮要求。
  • 元件端面应有良好冷却路径,必要时在 PCB 上增加铜箔或热通孔以改善散热。

八、储存与搬运

  • 储存环境应干燥、无腐蚀性气体,温度及相对湿度按厂方建议保存。长时间存放前建议根据厂商说明进行烘箱干燥处理以避免回流焊时出现焊接缺陷。
  • 贴片电容为极性器件,搬运与贴装时注意极性标识,防止倒装。

九、选型建议

  • 若应用纹波电流或高频性能要求高,请向供应商索取 ESR 与容抗频率曲线,并根据实际工况选择更高纹波等级或低 ESR 型号。
  • 若系统对寿命有更高要求,可考虑更高温寿命等级或增加散热设计以延长使用寿命。

十、结论与订购信息

RVT1E221M0810(ROQANG)为一款面向中小功率电源滤波与去耦的贴片铝电解电容,特点为高容值与小体积,适用于便携与嵌入式电源设计。在最终设计与量产前,建议获取完整数据手册(包括 ESR、阻抗曲线、回流焊曲线与推荐焊盘)并进行样品验证。若需技术资料或采购信息,请联系 ROQANG 官方渠道获取最新支持与批量报价。

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
