EWH1VM221F12OT是艾华集团(AISHI)推出的一款常规规格直插铝电解电容,针对低压直流电路的滤波、耦合及能量存储需求设计,兼具小型化封装与稳定性能,适用于消费电子、工业控制等多领域场景。
该电容为直插式铝电解电容,品牌为国内铝电解行业龙头艾华集团(AISHI),型号EWH1VM221F12OT。产品采用传统插件封装,无需特殊焊接设备,可兼容常规PCB插件工艺,是各类电子设备中替代同类进口或国产电容的可靠选择。
标称容值为220μF,精度±20%,满足多数电子电路对滤波、耦合的容值需求。±20%的精度符合工业级及消费级产品的常见设计要求,无需额外高精度匹配,降低电路设计复杂度。
额定电压35V,适用于12V、24V等低压直流系统(降额使用时可覆盖28V系统);纹波电流能力为270mA@120Hz,可有效抑制工频纹波,适合电源输出端滤波、音频电路耦合等需要处理交流纹波的场景。
电容体直径8mm(D8)、长度12mm(L12),脚间距3.5mm,属于小型化封装,可节省PCB布局空间,适配紧凑型电子设备(如小型路由器、智能小家电)的内部设计。
该电容凭借稳定的性能与小型化封装,广泛应用于以下场景:
工作寿命为2000hrs@105℃,即在105℃高温环境下连续工作2000小时后,容值变化率仍可控制在±20%以内,漏电流符合行业标准。实际常温(25℃)环境下,寿命可延长至数万小时,满足长期使用需求。
艾华集团采用自主研发的电解纸、铝箔材料,配合成熟的卷绕工艺,有效降低漏电流,提升电容稳定性。产品通过ISO9001质量管理体系认证,部分批次符合IATF16949汽车电子标准,品质可靠。
该电容为插件封装,安装时需注意:
艾华集团是国内铝电解电容领域的龙头企业,拥有20余年生产经验,产品覆盖高中低端市场。EWH1VM221F12OT作为常规型号,供货周期稳定,可满足批量生产需求;同时提供免费技术选型支持,协助客户优化电路设计。
该产品以高性价比、稳定性能及小型化设计,成为电子设备中低压滤波/耦合环节的优选元件之一。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
