EWH1JM102L25OT 产品概述

一、产品简介

EWH1JM102L25OT 是 AISHI(艾华集团)出品的一款直插式铝电解电容,封装为插件型,外形尺寸 D16 x L25 mm,适用于通过孔(THT)装配的电子电路板。该型号额定电压为 63V,容量为 1000µF,容量公差 ±20%,纹波电流为 930mA(@120Hz),脚间距 7.5mm,设计工作寿命为 2000 小时(105℃ 环境下)。该器件以其较高电压等级与大容量组合,适合用于中高压直流滤波、电源后级平滑以及工业类电源模块中。

二、主要性能特点

  • 高电容量与高电压等级的组合:1000µF/63V,能在较高电压条件下提供有效的滤波和能量储存。
  • 纹波承载力:930mA(@120Hz),适合中等纹波电流的电源滤波场合。
  • 紧凑外形:D16×L25 mm 的小体积设计,节省线路板空间,适合空间受限的工业与消费电子设备。
  • 插件封装:直插脚设计便于手工焊接或波峰焊、自动插件机装配,可靠性高,适合批量化生产。
  • 规范寿命:2000 小时 @ 105℃,满足部分工业级短期高温工作要求。

三、典型应用场景

  • 开关电源后端输出滤波、纹波抑制与能量缓冲。
  • 工业控制电源、驱动电源中的主滤波与旁路补偿。
  • LED 驱动、电机驱动器与逆变器的直流链路平滑(视具体电流和频率需求)。
  • 音频放大器的电源滤波与耦合(注意极性与杂讯要求)。
  • 其他需要在中高电压下进行短时能量释放与滤波的电子设备。

四、外观与机械参数

  • 封装形式:插件(直插/Through-Hole)。
  • 尺寸:电容体直径 16 mm,长度 25 mm(D16×L25)。
  • 脚间距:7.5 mm,适配常见的插件孔距设计。
  • 标识:产品外壳带有极性标识(负极带标识),便于正确安装。

五、安装与使用注意事项

  • 极性防错:本为有极电容,务必按电路规定的正负极方向安装,反向电压会导致电容损坏甚至爆裂。
  • 温度与寿命:标称寿命为 2000 hrs @ 105℃,实际使用时应采用温度、电压降额策略以延长寿命。长期在高温高压条件下工作会显著缩短器件寿命。
  • 纹波与发热:请注意实际电路中的纹波电流和工作频率,过高的纹波会使电容发热并加速老化。必要时选择并联多个电容或提升规格(更高纹波能力或更大体积)以降低热应力。
  • 焊接工艺:插件电容适用于波峰焊与手工焊,但应遵循厂商推荐的焊接温度和时间,避免长时间高温作用于电容引线及密封处,防止密封体受损或内部电解液劣化。
  • 安装方向:若电路板设计在高温或强振动环境,请确保电容安装牢固且通风良好,电容顶部泄压孔方向应有足够空间以确保安全释放。

六、存储与可靠性建议

  • 存放环境:建议存放在干燥、避光、清洁的环境中,避免高温高湿与有腐蚀性气体接触。
  • 上板前检验:长期存储后使用前应检查外观有无膨胀、漏液或端盖异常,必要时进行容量与漏电流测试。
  • 退化管理:对关键产品建议建立电容寿命管理策略(如定期更换或在线监测),以降低潜在的可靠性风险。

七、选型参考与替代建议

  • 若电路中纹波电流或温度更高,建议选用更高纹波电流规格或更长寿命(如 3000–5000 hrs @ 105℃)的电容器。
  • 如需更小体积或更长寿命,可以考虑固态或混合电容方案,但需综合考虑等效串联电阻(ESR)、成本与耐压等因素。
  • 在选型时应综合考虑额定电压、实际工作电压(建议降额使用)、容值公差、工作温度与纹波电流等关键参数。

EWH1JM102L25OT 以 AISHI 的制造能力为支撑,适合在对体积、电压与容量具有平衡需求的电源滤波场合使用。为获得最佳长期可靠性,建议按照实际应用的电压、温度与纹波条件进行适当降额与热管理设计。若需更详细的电气特性(如 ESR、漏电流随温度变化曲线)或样品与批量采购信息,请联系供应商或参考厂方数据手册。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
