ERF1EM681G16OT直插铝电解电容产品概述

一、产品基本定位

ERF1EM681G16OT是艾华集团(AISHI)推出的一款通用型径向直插铝电解电容,核心面向对容值精度要求适中、需耐受一定高温环境的电子电路设计,可替代同规格常规电解电容,兼顾性能可靠性与成本控制,适用于多数工业级及消费类电子设备。

二、核心电气参数解析

1. 容值与精度

产品标称容值为680μF(标识代码“681”对应68×10¹μF),精度为**±20%**,满足多数电子设备的滤波、耦合需求,无需额外高精度补偿,适合对容值一致性要求不苛刻的场景。

2. 额定电压

额定工作电压为25V DC,适用于12V、24V等低压直流系统(建议实际工作电压不超过16V,留足安全余量),可有效降低过压失效风险,适配多数低压电源电路。

3. 寿命与温度特性

  • 高温寿命:5000小时@105℃,指电容在105℃持续工作下的预期寿命;
  • 实际寿命延伸:遵循Arrhenius定律,温度每下降10℃,寿命约翻倍(如65℃环境下寿命可达约4万小时);
  • 工作温度范围:常规为**-40℃~105℃**,覆盖工业级设备的典型温度区间,适应高低温变化场景。

三、封装与物理规格

1. 封装类型

采用径向引线插件封装,引脚从电容体两端垂直引出,相比轴向封装更适合PCB板插件焊接,布局灵活度更高,便于批量生产安装。

2. 尺寸参数

  • 电容体直径:10mm(D10);
  • 电容体长度:16mm(L16);
  • 引脚间距:5mm;
  • 引脚特性:镀锡铜材质,焊接性优异,抗氧化能力强,可减少虚焊、冷焊风险。

3. 兼容性

尺寸符合常规插件电容的PCB板布局标准,无需特殊设计孔位,可直接替换同规格竞品电容,降低电路设计成本。

四、可靠性与环境适应性

1. 高温稳定性

5000小时@105℃的寿命参数,表明电容内部电解液挥发、氧化等老化过程在高温下速率较低,适合安装在电源模块、功率电路等易发热区域。

2. 耐纹波能力

常规1kHz频率下纹波电流约为80mA(艾华同规格典型值),可满足开关电源输出滤波、线性电源去耦等场景的纹波抑制需求。

3. 环保与环境兼容性

符合RoHS、REACH等环保指令,无铅无镉;耐湿度能力达85%RH(40℃环境下),可适应潮湿的工业环境。

五、典型应用场景

  1. 开关电源:24V系统的输出滤波(如小型LED电源、适配器电源);
  2. 工业控制板:PLC、变频器等设备的控制电路耦合、去耦电容;
  3. 消费电子:小型家电(加湿器、豆浆机)的电源模块滤波;
  4. 通信设备:低端路由器、交换机的辅助滤波电容。

六、品牌与品质背书

艾华集团(AISHI)是国内铝电解电容行业龙头企业,产品覆盖消费电子、工业控制、汽车电子等领域,通过ISO9001、IATF16949等质量体系认证。ERF系列电容生产过程严格管控,参数一致性好,批次差异小,供货稳定,可满足批量生产需求。

该产品凭借适中的参数规格、可靠的高温性能及广泛的兼容性,成为中低压电子电路设计的高性价比选择。

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.

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
