VT1A221M0605 产品概述

一、产品简介

VT1A221M0605 是 ROQANG(容强)推出的一款贴片型铝电解电容,额定容量 220µF,公差 ±20%,额定电压 10V。该器件采用 SMD 封装,电容体尺寸小巧(直径 6.3mm × 长度 5.4mm),适合空间受限的表面贴装电路。工作温度范围宽 (-40℃ ~ +105℃),并在 105℃ 下具有 2000 小时的寿命保证,适用于中高温度工况的电子产品。

二、主要电气与机械参数

  • 容值:220µF ±20%
  • 额定电压:10V
  • 纹波电流:90mA @ 120Hz(注意:随频率和温度变化)
  • 封装:SMD,尺寸 D6.3 × L5.4 mm
  • 工作温度:-40℃ ~ +105℃
  • 寿命:2000 hrs @ 105℃
  • 品牌:ROQANG(容强)

三、性能特点与设计要点

  • 小尺寸高容量:在 6.3×5.4mm 的体积下实现 220µF 的容量,适合移动设备与紧凑型电源滤波应用。
  • 温度与寿命:105℃/2000h 的规范适合对长期可靠性有要求的工业或消费类电子。实际使用环境温度越低,预期寿命越长。
  • 纹波处理:标称 90mA@120Hz,适用于低至中等纹波电流的电源滤波与去耦场景;在高频或高纹波应用需参考厂方频率特性曲线并做裕量设计。
  • 极性注意:为铝电解电容,必须严格区分极性,避免反接或出现反向偏置。

四、典型应用场景

  • 移动终端、便携式音视频设备的电源后端滤波与去耦;
  • 无线通信模块、物联网终端供电滤波;
  • 工业控制电源、背光驱动与小型 DC-DC 降压稳压输出端滤波;
  • 对体积敏感且要求中等寿命的消费电子电源滤波场合。

五、封装安装与可靠性建议

  • 回流焊:建议按照厂方回流温度曲线进行焊接,避免长时间高温或多次超温循环;严格遵循 PCB 焊盘及阻焊设计规范以降低机械应力。
  • 存储与再形成:长期存储后电容可能需再形成(加低压逐步回升)以恢复性能;存储环境建议干燥、常温并避免高湿高温。
  • 机械应力:贴装后避免 PCB 弯曲和强烈振动冲击,插件或压装工艺需做好应力释放。
  • 清洗与维护:尽量避免超声波清洗或使用强腐蚀性溶剂清洗,必要时参考厂方清洗建议。

六、选型与应用注意事项

  • 电压裕量:建议在设计中为电容工作电压留有裕量,避免长期满压或脉冲超压;典型工程实践会考虑 70%~80% 的电压利用率以提高寿命。
  • 纹波与温升:若电路纹波电流接近或超过规格值,应选用更高纹波能力或并联多只电容,并关注温升对寿命的影响。
  • 替换与等效:选型时考虑容量、公差、额定电压、ESR/ESL 特性及尺寸匹配,优先选择同系列或同厂商等效型号以保证兼容性。

VT1A221M0605 以其小型化、高容量和较高工作温度能力,为对尺寸和可靠性有要求的电源滤波与去耦设计提供了实用选择。选用时请结合实际工作频率、纹波电流和热环境进行合理的电气与机械设计。若需更详细的电气特性曲线(如 ESR、耐压和纹波随频率的变化)或回流焊工艺参数,建议联系 ROQANG 厂方获取完整技术资料。

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
