RVT1H221M1010 — ROQANG(容强) 220µF ±20% 50V SMD 铝电解电容 产品概述

一、产品简介

RVT1H221M1010 是 ROQANG(容强)推出的一款贴片型铝电解电容,标称容量 220µF,公差 ±20%,额定电压 50V。器件为轴向短身圆筒型 SMD 封装,电容体直径 10mm、长度 10.2mm,适配表面贴装工艺,主要面向开关电源滤波、直流母线旁路与电源退耦等场合。该型号在 120Hz 下的额定纹波电流为 230mA,工作温度范围为 -40℃ 至 +105℃,并在 105℃ 条件下保证 2000 小时的寿命,适用于要求中长期高温稳定性的工业电子设备。

二、主要规格(概览)

  • 型号:RVT1H221M1010
  • 品牌:ROQANG(容强)
  • 电容值:220µF
  • 容差:±20%
  • 额定电压:50V DC
  • 纹波电流:230mA @ 120Hz
  • 外形尺寸(电容体):直径 10mm × 长度 10.2mm(SMD)
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 小时 @ 105℃
  • 封装形式:贴片(适合 SMT 自动贴装加工)

三、产品特性与优势

  • 紧凑体积:D10×L10.2mm 的短柱形结构,在容量与体积之间取得平衡,适合空间受限但需要相对较大电容量的电源滤波应用。
  • 高温寿命保证:2000 小时@105℃ 的寿命等级,表明该器件在高温环境下仍能维持较长时间的性能稳定性,适合工业级电源与设备。
  • 良好纹波处理能力:120Hz 纹波电流额定值 230mA,适用于整流后滤波、线性/开关电源的低频纹波抑制。
  • 贴片化便于量产:SMD 封装兼容主流贴片机和回流焊工艺,提高生产效率并利于表面贴装组装(SMT)流程的自动化。

四、典型应用场景

  • 开关电源输出滤波与输入旁路(尤其中低功率及板级电源管理场合)。
  • 工业控制电源、通信设备、仪器仪表中的直流稳压与能量储备。
  • PCB 上的去耦与瞬态功率支撑(靠近功率芯片或稳压器处使用,可改善瞬态响应)。
  • 非严格汽车级但要求高温运行的工业类产品(如电机驱动、电源模块等),在使用前请确认是否满足系统可靠性要求与认证需求。

五、设计与选用建议

  • 温度与电压余量:为延长使用寿命,建议在实际应用中对电容进行额定电压与工作温度的适当降额(例如尽量避免长期满额定电压和高温工况同时长期存在),以提高可靠性。
  • 布局与焊接:将电容尽量靠近被滤除噪声源(例如稳压器输出、开关管)布局,缩短信号回路长度以降低寄生阻抗。采用厂方推荐的 PCB 封装尺寸及焊盘布局,确保良好焊接强度与热传导。
  • 焊接工艺:遵循 ROQANG 提供的回流焊工艺指南,避免重复高温循环或超出厂方规定的温度/时间限制。若组件长时间放置或受潮,必要时按厂家建议进行烘烤预处理以避免焊接缺陷。
  • 频率与纹波匹配:本型号在低频至中低频范围(如工频整流后的 120Hz)表现出色;若系统包含高频开关纹波,应结合低 ESR 的薄膜或固态电容并联使用以优化高频响应。

六、可靠性与检验要点

  • 额定寿命与高温性能是该系列的核心指标:2000hrs@105℃ 代表在该温度下的设计寿命验证。实际应用寿命受工作温度、直流偏置、纹波电流等多因素影响,应根据系统使用工况估算等效寿命。
  • 检测项目建议:容量保持率、漏电流、等效串联电阻(ESR)、纹波承载能力以及外观(鼓胀、泄漏)等常规电容检验项目。

七、包装与生产线兼容性

RVT1H221M1010 为 SMD 形式,适配自动贴装生产线,便于卷盘进料与高速贴装。建议在采购时与供应商确认具体卷带包装规格(如卷带长度、托盘或其他包装形式)以及可追溯的批次/质检报告。

总结:RVT1H221M1010 是一款面向工业级电源滤波与去耦应用的短体贴片铝电解电容,兼具较大电容量、高温寿命和 SMT 可装配性,是需要在有限 PCB 面积内实现可靠滤波与能量缓冲场合的合适选型。购买与设计采纳前,建议参考 ROQANG 的详细数据手册与焊接指南以获得最佳性能与可靠性。

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.
