ERS1HM681W20OT 产品概述
一、产品简介
ERS1HM681W20OT 为艾华集团（AISHI）推出的一款直插（插件）铝电解电容，额定容量 680µF，精度 ±20%，额定电压 50V。器件为径向引线封装，电容体直径 12.5mm，长度 20mm，脚间距 5mm，常见标记 D12.5×L20mm。该系列设计用于要求长期稳定性的电源旁路、滤波与储能场合，适配批量插件安装工艺。
二、主要性能与规格要点
- 容值：680µF ±20%
- 额定电压：50V
- 结构：径向引线（直插）铝电解电容
- 尺寸：直径 12.5mm × 长度 20mm，脚间距 5mm
- 使用寿命：10000 小时 @ 105℃（高温长寿命设计）
- 品牌/型号：AISHI（艾华） / ERS1HM681W20OT
三、应用场景
适用于各类工业与消费电子的开关电源滤波、直流母线旁路、整流后滤波、DC-DC 变换器储能、音频放大器电源滤波及其它需要大容量、高温寿命的电路。因为为插件封装，也常用于维修替换与原理样机开发。
四、安装与使用注意事项
- 在安装时注意极性标识，避免反向焊接或极性连接错误；反向电压会导致泄漏、鼓包甚至爆裂。
- 遵循制造商推荐的焊接工艺和温度曲线，尽量避免长时间高温，焊接后允许充分冷却和老化处理以恢复电解性能。
- 使用时应避免超过额定电压与超额纹波电流，长期在额定温度附近工作会加速容量衰减，建议按系统热设计留有裕量。
- 储存时防潮、防挤压，避免长期在高温高湿环境下堆放。
五、可靠性与替换建议
该型号标称寿命 10000hrs@105℃，适合对高温稳定性有较高要求的场合。在设计选型时，如需更长使用寿命或更低 ESR，可考虑更大体积或固态/钽电容作为替代；若替换须保证相同或更高的额定电压、容值和等效或更好机械尺寸匹配，以便于插件孔距与安装。
六、选型小结
ERS1HM681W20OT 以其 680µF/50V 的容量组合、小巧的 D12.5×L20mm 尺寸与 10000 小时@105℃ 的高温寿命，适合对容量需求较大且要求插件安装的电源滤波与储能场合。选型时应综合考虑工作温度、纹波电流、ESR 要求及机械安装条件，以确保电容在目标应用中的长期可靠性。若需更详细的电气参数（如阻抗、等效串联电阻 ESR、泄漏电流与纹波电流额定值），建议索取厂商的完整数据手册并按照规范进行验证。

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.
