EGW2CM220F12OT是艾华集团(AISHI) 推出的一款直插式铝电解电容,属于中低压通用型电容产品。型号命名中:
标称容值22μF,精度±20%,实际容值范围为17.6μF~26.4μF,满足滤波、耦合等电路对容值偏差的常规要求,无需额外高精度匹配。
额定直流电压160V,是该电容的核心电气参数——使用时电压不得超过此值(含纹波电压叠加),否则会导致电容内部电解质分解、漏液甚至击穿,影响设备安全。
电容体直径8mm、长度12mm(不含引脚),引脚采用标准直插式设计(引脚间距2mm左右,符合插件焊盘规范),属于小型化封装,可适配空间紧凑的PCB布局,尤其适合便携式设备、小型控制板等场景。
采用插件式设计,兼容手工焊接、波峰焊、浸焊等主流工艺,无需特殊焊接设备,适合中小批量生产或原型开发;引脚强度适中,不易折断,便于PCB装配与调试。
内部采用腐蚀铝箔(增大表面积提升容值)、液态电解质(提供离子导电通路)、铝外壳(封装与散热),搭配橡胶塞(密封防漏液),结构稳定,长期使用可靠性高。
电容外壳印有负极标识(白色条纹或引脚长度差异),需严格对应PCB正负极焊盘,避免反接;尺寸D8×L12mm可直接替换同参数的其他品牌直插电容,兼容性良好。
用于开关电源、线性电源的整流滤波电路,平滑交流整流后的电压纹波,提升电源输出稳定性;也可作为储能元件,应对瞬间负载波动(如电机启动、继电器切换)。
广泛应用于空调、洗衣机、冰箱等家电的控制电路电源模块,保障MCU、传感器等低功耗元件的供电稳定;同时用于信号耦合电路,隔离直流信号、传递交流信号。
在LED驱动电路中作为输出滤波电容,去除高频纹波,避免LED闪烁,提升发光稳定性;适配12V~160V范围内的LED驱动电源设计。
如仪器仪表、通信终端(如路由器、交换机)的辅助电源模块,或小型充电设备的滤波电路,利用其小型化封装节省设备内部空间。
艾华集团(AISHI)是国内铝电解电容行业龙头企业,拥有30余年研发生产经验,产品符合RoHS环保标准(无铅、无镉),通过ISO9001、IATF16949等质量体系认证,广泛应用于国内外家电、汽车电子、工业控制等领域。
EGW2CM220F12OT采用艾华标准化生产工艺,性能一致性好,寿命可达1000小时(+85℃、额定电压下),满足多数设备的使用寿命要求。
该产品凭借稳定的性能、小型化封装与亲民的成本,成为中低压电路的高性价比选择,可满足多数通用电子设备的基础电容需求。

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.
