VT2A220M0810 产品概述

一、产品简介

VT2A220M0810 是 ROQANG(容强)推出的一款贴片型铝电解电容,额定容量 22µF,允许偏差 ±20%,额定电压 100V。电容体为 SMD 结构,外形尺寸直径 8mm、长度 10.2mm,适用于空间受限但需承受较高直流电压的电源滤波与旁路场合。

二、主要技术参数

  • 容值:22µF ±20%
  • 额定电压:100V DC
  • 纹波电流:87mA @ 120Hz
  • 封装尺寸:D8 × L10.2mm(SMD)
  • 工作温度:-40℃ 至 +105℃
  • 使用寿命:2000 小时 @ 105℃(典型)
  • 极性:有极性(贴装时注意标示)

三、性能特点

  • 高耐压设计,适合中高压直流回路的能量存储与滤波。
  • 紧凑 SMD 封装,支持自动贴装和回流工艺,便于表面贴装生产线应用。
  • 在标称频率下有明确的纹波电流指标,利于热设计与可靠性评估。

四、典型应用场景

  • 开关电源与DC-DC转换器的输入/输出滤波
  • 电源总线去耦与能量储存(高压侧)
  • 工业控制、电源模块、通信设备的高压滤波部位

五、可靠性与寿命说明

该系列标注寿命为 2000 小时 @ 105℃。按常用经验规则(温度每降 10℃,寿命近似翻倍)可估算在 85℃ 时寿命约为 8000 小时。实际寿命受工作电压、纹波电流、环境温度与散热条件影响,设计时应考虑适当的裕量与降额。

六、设计与使用建议

  • 严格注意极性,禁止在反向电压下工作。
  • 纹波电流不得长期超过额定值(87mA@120Hz),否则会导致发热并缩短寿命;若不知道 ESR,应按实际电流、温升要求留有裕度。
  • 对长期可靠性要求高的场合建议对额定电压进行适当降额,并做好散热设计。
  • 焊接时请参照厂家推荐的回流曲线与预热要求,避免过长时间的高温暴露。

七、采购与技术支持

选型或批量采购前,请向 ROQANG 或授权分销商索取完整规格书(包括 ESR、介损、回流温度曲线及寿命试验报告)以便进行电路仿真与可靠性评估。对于特殊环境或更高纹波需求,可咨询厂方是否有更高性能的替代型号。

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
