ERS1CM471F12OT是艾华集团(AISHI) 推出的一款通用型径向直插铝电解电容,属于中容值、中低压铝电解电容范畴。该产品以「稳定电气性能+紧凑封装+高高温可靠性」为核心特点,适配消费电子、小型家电、工业控制等多领域的滤波、耦合及能量存储需求,是替代普通低寿命电容的高性价比选择。
标称容值为470μF,精度等级**±20%**,符合商业级铝电解电容的常规精度要求,无需额外匹配高精度电容即可满足大多数电路的滤波/耦合需求。
直流额定电压16V(DC),需注意:交流电路中使用时,其峰值电压不得超过16V,避免过压击穿失效。
核心可靠性指标为7000hrs@105℃(105℃持续高温下稳定工作7000小时),远高于普通铝电解电容(通常2000-3000hrs@105℃)的寿命水平,适合长期工作在温度波动较大的场景(如密闭机箱、高温环境设备)。
采用优化电解液配方与铝箔腐蚀工艺,等效串联电阻(ESR)较低,可有效降低滤波电路纹波系数;频率特性适配120Hz(市电整流后频率),适合工频整流滤波场景。
径向引线直插式(插件):两个引脚从电容体两端垂直引出,比轴向引线电容更节省PCB纵向空间,适配高密度布局设计。
需注意:PCB设计时需严格匹配尺寸,避免焊接困难或布局冲突。
结合高温寿命指标,推测工作温度范围为**-40℃~105℃**,可适应低温(如北方户外设备)与高温(如密闭机箱)环境。
符合IEC 60384-4标准:40℃、95%RH环境下持续1000小时后,绝缘电阻仍≥100MΩ·μF,避免潮湿导致漏电/短路。
通过行业常规测试:振动(10-500Hz,10g加速度)、冲击(50g峰值加速度,11ms持续),可承受设备运输/使用中的轻微振动冲击,不易出现引脚断裂或电容体松动。
额定电压+105℃环境下老化1000小时后,容值变化率≤10%、损耗角正切值变化率≤30%,性能衰减缓慢,保证长期可靠性。
艾华集团是国内铝电解电容龙头企业(成立于1985年),拥有多项核心专利,产品远销全球30+国家,是华为、小米、美的等知名企业供应商。
通过ISO 9001(质量管理)、ISO/TS 16949(汽车行业)、RoHS(环保)认证,符合欧盟环保要求(无铅、镉等有害物质)。
全自动生产线保证产品一致性;每批次抽样检测合格出厂;提供完善售后支持,质量问题可退换货。
该产品凭借高性价比与可靠性能,成为电子电路设计中通用滤波/耦合场景的优选元件。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
