ERS1VM221F12OT 产品概述
一、产品简介
ERS1VM221F12OT 为 AISHI（艾华集团）直插径向铝电解电容，额定容量 220µF，额定电压 35V，体径 8mm，体长 12mm，适用于常见的插件电源滤波与去耦场合。封装为径向引线，脚间距 3.5mm，标准插件安装，适配紧凑型 PCB 布局。
二、主要技术参数
- 容值：220µF（ ±20% ）
- 额定电压：35V
- 封装尺寸：径向引线，电容体 Ø8mm × L12mm
- 引脚间距：3.5mm（中心距）
- 工作寿命：7000 小时 @ 105℃
- 品牌：AISHI（艾华集团）
（以上为出厂标称参数，详情请参见厂家规格书以确认测试条件和额外电特性）
三、结构与外形
本系列为传统铝电解结构，采用电解质注入密封，带极性标识。径向引线利于通孔插件生产与手工焊接，紧凑的 D8×L12 体积便于在空间受限的电路板上布置成组使用。脚间距 3.5mm 适配小间距插件孔阵列。
四、性能与特点
- 高容量密度：220µF 在 8×12mm 的小封装内提供较大容量，适合小功率电源滤波与旁路。
- 耐高温可靠：额定寿命 7000h@105℃，适合要求长期稳定性的工业级或高温环境设计（应结合实际使用温度与周期曲线考虑寿命余量）。
- 插件便捷：径向引线适合传统通孔焊接，维修更换方便。
- 常见铝电解特性：对频率和温度敏感；直流漏电、等效串联电阻（ESR）和纹波电流随温度与频率变化，应在设计时考虑相应裕量。
五、典型应用
- 开关电源与线性稳压器的输入/输出滤波
- 工业控制、仪器仪表、小型功放和车载电子（在符合温度/振动要求时）
- 电源去耦、耦合与储能场合，尤其在空间受限但需大容量的位置
六、使用与焊接建议
- 极性注意：为极性电容，请严格按电路标识安装，反接会导致失效或爆裂。
- 温度与寿命：长期工作温度每降低 10℃，寿命大致延长一倍；设计时应留有寿命裕度。
- 焊接工艺：通孔焊接时避免长时间高温加热，推荐回流/波峰焊工艺参数遵循厂家建议，焊接温度与持续时间过大会影响内部电解质。
- 安装留距：建议在 PCB 上为电容底部留出适当空间以利散热，并确保孔距与 3.5mm 对应。
七、储存与可靠性注意
长时间储存后电容可能出现自放电或电容值变化，长期储存（>2年）建议进行“恢复”处理（按厂家说明施加额定电压一段时间）以恢复性能。存放环境应干燥、无腐蚀性气体、温度适中。
八、选型与注意事项
在选型时除容量、电压和尺寸外，还应关注 ESR、最大允许纹波电流、低温性能与机械振动耐受性等参数；若应用为车载或高脉冲场合，建议咨询厂方或参考替代系列以获得更详细的电气特性曲线与可靠性数据。
如需完整规格书、ESR 与纹波电流曲线、寿命加速试验数据或大批量采购信息，可联系 AISHI 或授权分销商获取原厂文件。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
