EWH1CM471F120T 产品概述
一、产品基本规格
EWH1CM471F120T 为 AISHI（艾华集团）出品的直插铝电解电容，主要参数如下：
- 容值：470 µF（±20%）
- 额定电压：16 V
- 纹波电流：310 mA（@120 Hz）
- 外形尺寸：φ8 mm × L12 mm（D8×L12mm）
- 引脚间距：3.5 mm（径向引线、插件）
- 工作寿命：2000 小时（@105 ℃）
- 封装形式：径向引线（直插、插件）
二、主要特性
- 小型化体积、高容量密度：φ8×12mm 的紧凑外形适合空间受限的电路板设计。
- 良好滤波与旁路能力：470 µF 容量配合 310 mA 的纹波电流特性，适合中等功率的电源滤波与去耦。
- 可靠性数据明确：标注 105 ℃ 下 2000 小时的寿命评级，便于热设计与寿命评估。
- 插件形式便于手工或波峰焊装配，适用于传统 PCB 工艺。
三、典型应用场景
- 开关电源与线性稳压电源的输出滤波与能量储存
- 数字电路与模拟电路的去耦、稳压旁路
- 工业控制、通信设备和消费电子中需要中等容量的小体积滤波电容场合
- 作为电源上电瞬态抑制与局部储能元件
四、安装与使用注意事项
- 极性识别：本产品为极性铝电解电容，安装时必须注意正负极（负极通常有明显标识），严禁反向接入。
- 电压与温度退让：建议在实际使用中对额定电压做适当退让以延长寿命；避免长期满压、高温环境工作。
- 纹波与涌流：避免长期超过额定纹波电流和频繁的大幅涌流，否则会加速电解质失效。
- 焊接注意：插件工艺下应控制焊接温度与时间，避免过热导致电容性能下降或寿命缩短。
五、可靠性与保养建议
- 使用寿命：标称 2000 h@105 ℃，在较低工作温度下寿命会显著延长；一般经验法则为温度每降低 10 ℃，寿命约延长一倍（需结合实际制造商曲线评估）。
- 储存与搬运：建议置于干燥、常温环境，避免潮湿、高温及长期光照；在装配前检查外观及引脚完整性。
- 预防故障：系统设计中应考虑过压、反向电压保护及适当的散热路径，以保障长期稳定运行。
六、订购与技术支持
- 型号：EWH1CM471F120T
- 品牌：AISHI（艾华集团）
- 封装：径向引线，8×12 mm，脚间距 3.5 mm 如需更详细的电气特性（如 ESR、等效串联电阻随频率/温度的曲线）、波形数据或可靠性试验报告，请联系供应商或参考厂方规格书以获得完整规范与检验数据。

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.
