ERS1HM221G13OT是艾华集团(AISHI) 推出的一款通用型径向直插铝电解电容,主打高性价比与稳定可靠性,适用于多种中低频率的电路滤波、耦合场景,是工业控制、消费电子等领域的常用选型。
该电容属于直插铝电解电容类别,采用径向引线封装(引脚从电容体两端垂直引出),核心定位为通用型器件——既满足消费电子的成本控制需求,又能覆盖工业设备的基本可靠性要求。其型号编码“ERS1HM221G13OT”中,“221”对应220μF容值,“50V”为额定电压,“13”代表电容体长度13mm,清晰对应产品的核心参数特征。
容值为220μF(微法),精度±20%——这一精度水平无需额外校准,即可满足大多数常规电路的需求(如电源滤波、音频耦合),在工业级、消费级设备中性价比突出,避免了高精度器件的成本浪费。
额定电压为50V直流——需注意铝电解电容的额定电压为直流电压(DC),实际应用中应确保电路电压不超过该值(交流电压需按峰值计算,避免过压损坏)。50V的电压等级适配24V、36V等常见电源系统,覆盖范围广。
寿命指标为7000hrs@105℃——即在105℃的高温环境下,连续工作可稳定运行7000小时。这一参数是铝电解电容可靠性的关键:105℃属于高温工况(常见于工业设备、车载电子的局部高温区域),7000小时的寿命长度远高于普通民用级电容(一般为2000-5000hrs@105℃),适合长期稳定运行的设备。
采用径向引线封装,引脚从电容体两端垂直引出,相比轴向封装(引脚平行于电容体),更节省PCB空间,且焊接时无需特殊定位;引脚采用镀锡工艺,抗氧化能力强,长期使用不易出现虚焊、接触不良问题,保障电路稳定性。
ERS1HM221G13OT的参数适配性强,常见应用包括:
艾华集团(AISHI)是国内铝电解电容领域的龙头企业,产品通过ISO9001、IATF16949等认证,广泛应用于汽车、工业、消费电子等领域。ERS1HM221G13OT的参数设计符合IEC 60384-4等行业标准,引脚焊接性能、寿命稳定性均经过多轮测试验证,能有效降低设备的长期维护成本。
总结来说,ERS1HM221G13OT是一款高性价比、小体积、长寿命的通用直插铝电解电容,适合对成本敏感且需要稳定可靠性的电路设计,是工程选型中的常用优质选项。
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.
