RVT1C471M0607 产品概述

RVT1C471M0607 是 ROQANG(容强)推出的一款贴片型铝电解电容器,额定容量为 470 µF,额定电压 16 V,体积小巧(D6.3 × L7.7 mm),适合对容量与体积有严格要求的消费电子、便携设备和工业控制电源滤波与去耦场合。该型号在 105°C 环境下标称寿命为 2000 小时,纹波电流规格为 185 mA(120 Hz),公差 ±20%。

一、主要规格与结构特点

  • 容值:470 µF,公差 ±20%
  • 额定电压:16 V
  • 纹波电流:185 mA @ 120 Hz(典型测试频率)
  • 封装形式:SMD(贴片型),外形尺寸 D6.3 × L7.7 mm
  • 工作温度范围:-40°C ~ +105°C
  • 使用寿命:2000 hrs @ 105°C
  • 引脚与极性:贴片极性标识明显,注意焊接方向

该器件采用铝电解技术,具备单位体积较高的容量和较好的高频滤波能力,适合在受限空间内提供可靠的能量储备与纹波抑制。

二、性能优势与应用场景

  • 体积小、容量大:D6.3×L7.7 mm 的小外形使其适用于便携设备、消费电子、模块化电源和紧凑型母板设计;470 µF 的容量可在有限空间内保证良好的去耦与稳压能力。
  • 高温寿命保证:105°C 下 2000 小时的寿命指标,适合工业级或高温环境的设计要求。
  • 合理的纹波能力:185 mA@120 Hz 的纹波电流能力满足多数低功耗开关电源与线性稳压后的滤波需求。
  • 贴片工艺兼容:适合自动贴装与回流焊工艺,利于批量生产和 SMT 流程集成。

典型应用包括稳压器输出滤波、开关电源的输入/输出滤波、便携式音频/视频设备、嵌入式控制板和通信设备的局部去耦。

三、设计与使用建议

  • 额定电压与降额:为延长寿命,建议设计时对电压进行降额使用(例如 60%~80% 额定电压),尤其在高温环境下应更严格降额。
  • 温度对寿命的影响:按照常用经验法则(温度每降低 10°C,寿命翻倍),在 85°C 工作温度下,其寿命可显著高于 2000 小时(仅为估算,具体以厂方数据为准)。
  • 纹波与 ESR:给定的纹波电流是以 120 Hz 测试的参考值;在高频开关电源中,实际纹波频率远高于 120 Hz,器件的等效串联电阻(ESR)与阻抗随频率变化,建议在设计前查阅完整数据手册或进行实测,确保电容在实际频率下的发热在可接受范围内。
  • 布局与散热:在 PCB 布局上尽量将电容靠近电源引脚或稳压器输出端,缩短信号回路环路;必要时增加散热通道,有利于降低温升,延长寿命。
  • 焊接与回流:该型号为 SMD 贴片元件,兼容常见回流焊工艺。具体回流温度曲线应遵循制造商推荐的焊接规范,避免多次高温回流造成电解液性能下降。
  • 存储与调整:铝电解电容长期储存会有自放电或形式电解质变化,建议按厂商要求储存并在长期库存后进行必要的恢复充电(reform)或更换。

四、封装与采购信息

  • 品牌:ROQANG(容强)
  • 封装:SMD 贴片,尺寸 D6.3 × L7.7 mm
  • 产品型号:RVT1C471M0607(标注规格 470 µF,16 V)
  • 包装与交付:常见为卷带(Tape & Reel)方式,便于 SMT 自动化生产;大批量采购可向厂商或授权分销商咨询供货与最小订购量。

五、注意事项与兼容替代

  • 在替换或替代元件时,应注意容量、公差、额定电压、纹波电流、工作温度与寿命等级(尤其是 105°C 等级)等关键参数一致或更优。
  • 使用中避免长期在高电压、高温、高纹波工况下运行,以防加速老化、漏电增加或寿命急剧下降。
  • 如需在高频大纹波的开关电源中使用,建议配合低 ESR 的固态电容或钽电容进行级联滤波,以获得更好的温升和寿命表现。

总结:RVT1C471M0607 是一款用于紧凑空间电源滤波与去耦的高容量贴片铝电解电容,兼顾体积与性能,在消费电子与工业电源场景中具有良好适配性。选择和使用时请结合实际工况、厂方完整数据手册与 PCB 布局优化以获得最佳可靠性与寿命。

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.
