RT1E221M0810 产品概述
一、产品简介
RT1E221M0810 是 ROQANG（容强）出品的一款贴片型铝电解电容，标称容量 220µF，额定电压 25V，公差 ±20%。电容体尺寸为直径 8mm × 长度 10.2mm（SMD，D8×L10.2mm），适用于要求体积小、容量较大且需表面贴装的电子设备电源与滤波电路。
二、主要电气参数
- 容值：220µF
- 精度：±20%
- 额定电压：25V
- 纹波电流：183mA @ 120Hz
- 工作温度范围：-40℃ ～ +105℃
- 工作寿命：2000 小时（105℃）
说明：纹波电流参数对封装内温升和寿命影响显著，设计时应根据实际纹波电流进行热平衡评估。
三、产品特点
- 小尺寸、大容量：8×10.2mm 的紧凑体积，适合高密度 PCB 布局。
- 宽温区与高温寿命：-40℃ 至 +105℃ 工作范围，2000 小时高温寿命，适合汽车电子（非最高可靠性等级）、工业电源等中高温场合。
- 良好滤波性能：适合电源输出端和稳压后滤波，能有效抑制低频纹波。
- 表面贴装工艺：SMD 封装便于自动贴装和回流焊，提高生产效率。
四、典型应用场景
- 稳压器输出端及输入滤波（线性与开关电源）
- DC-DC 转换器输出滤波与储能
- 工业控制、消费电子、通信设备的电源去耦
- 需要体积受限但容量较大的场合
五、可靠性与寿命
该型号按说明在 105℃ 环境下额定寿命为 2000 小时。实际使用寿命受电压应力、纹波电流、环境温度以及散热条件影响。为延长寿命，建议在靠近高温或长时间工作的场景中适当进行电压降额和降低纹波负载，并预留足够的散热路径。
六、封装与焊接建议
- 封装类型：SMD，外形直径 8mm，长度 10.2mm。
- 焊接：建议遵循元件厂商的回流焊曲线（一般按无铅回流标准，峰值温度与时间需参照具体数据表）。
- 安装：注意极性标识（电解电容有明显负极或正极标记），避免反向焊接或贴装。建议在 PCB 设计时为热膨胀与电容散热预留足够的焊盘和通孔散热方案。
七、选型注意与替代参考
- 如果电路中纹波电流较大，应选用更高纹波电流等级或并联多个电容分担热量；并注意 ESR、ESL 等参数对稳压和瞬态响应的影响（具体 ESR/阻抗请参照型号数据表）。
- 需更高寿命或工业级应用时，可考虑寿命更长或耐高温等级更高的铝电解或固态电容替代。
八、储存与使用注意
- 储存时避免潮湿、高温与强酸碱环境，未使用的电容请保留原包装。
- 使用前检查极性、外观无泄漏或胀鼓，焊接后建议经过额定电压的检验与老化测试。
总结：RT1E221M0810 以小体积提供较大容量与合理的纹波处理能力，适合表面贴装电源滤波与去耦场合。在实际设计中应结合纹波电流、工作温度和散热条件进行合理选型与布局，以保证长期可靠运行。

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.
