RVE1C220M0405 产品概述
一、产品简介
RVE1C220M0405 为 ROQANG（容强）出品的贴片型铝电解电容，容值 22µF，额定电压 16V，体积小巧（D4 × L5.4mm），适用于对体积与成本敏感的表面贴装去耦、滤波与电源旁路场合。器件为极性电容，请按正确极性安装。
二、主要参数
- 容值：22µF（公差 ±20%）
- 额定电压：16V
- 纹波电流：110mA @ 120Hz
- 等效串联电阻（ESR）：1.5Ω（标称）
- 体积：直径 4mm × 长度 5.4mm（SMD，D4×L5.4mm）
- 工作温度：-55℃ ～ +105℃
- 工作寿命：2000 小时 @ 105℃
三、电气特性与热管理
纹波电流产生的自热由 I_rms² × ESR 决定，长期超额纹波会导致温度上升、寿命缩短和电容容量降低。请根据实际工作频率和纹波频谱评估等效加热，必要时选用并联电容或更低 ESR 的器件以降低发热。
四、可靠性与寿命评估
标称寿命为 2000 小时（105℃）。按常用温度加速经验法则（每降 10℃ 寿命约翻倍），在 85℃ 下寿命可显著延长（约数倍量级），但此为估算，具体寿命受工作电压、纹波、散热条件与实际制造差异影响，应以实际可靠性试验为准。
五、典型应用
- 开关电源与线性稳压器输入/输出去耦
- 模拟电路电源滤波与旁路
- 小型便携设备的电源旁路与去耦
- 通信、音频电路中对瞬态响应有中等要求的场合
六、选型与使用建议
- 对纹波和发热敏感的场合，优先考虑更高纹波能力或更低 ESR 的替代品；如需提高寿命可选择额定电压与实际工作电压之间留有裕量。
- 避免反向电压和过压；启动或异常瞬态可能对极性电容造成破坏。
- 并联小值低 ESR 电容（如陶瓷）可改善高频去耦和降低等效 ESR/ESL。
七、封装与贴装注意事项
- 为保证焊接可靠性，请参照厂商推荐的焊盘与回流曲线。贴片铝电解对高温和长时间加热敏感，需控制回流峰值温度与停留时间。
- 布局时应留出顶端极性标识可视区域，避免机械应力集中，焊接后应避免强烈挤压或弯曲。
八、结论
RVE1C220M0405 以其小型 SMD 封装、16V/22µF 的规格适合中低功率电源滤波与去耦应用。使用时关注纹波、电压余量与热管理，可通过合适的并联和布板策略提高整体性能与寿命。若需更高纹波承受能力或更长寿命，请参考容强的更高等级产品或咨询厂方技术支持。

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.
