KEMET T491X226K050AT 钽电容产品概述

一、产品基本属性

KEMET T491X226K050AT是基美电子(KEMET)推出的工业级表面贴装钽电解电容,属于T491系列核心产品。该电容针对中高压、宽温环境下的稳定滤波与储能需求设计,继承了基美钽电容“体积小、容值稳定、可靠性高”的核心优势,广泛适配工业控制、通信等领域的电路场景。

二、核心参数详解

该电容的关键参数精准匹配多数工业应用的性能要求,具体如下:

  1. 容值与精度:标称容值22μF(微法),容差±10%,可稳定提供电荷存储能力,满足滤波、耦合、去耦等基础功能;
  2. 额定电压:50V DC(直流额定电压),允许工作时的最大直流电压为50V,适配中高压电源电路(如DC-DC转换器输出端);
  3. 等效串联电阻(ESR):600mΩ(毫欧级),低ESR特性可有效降低纹波噪声,减少电路发热,提升电源转换效率;
  4. 工作温度范围:-55℃~+125℃,覆盖工业级宽温区间,可在极端低温(如北方户外设备)或高温(如工业烤箱周边模块)下稳定工作;
  5. 电容类型:钽电解电容,采用钽粉作为阳极材料,相比普通铝电解电容,体积更小、容值一致性更好。

三、封装与尺寸规格

该电容采用基美标准CASE-X封装,物理尺寸为7.3mm×4.3mm×4.3mm(长×宽×高),属于表面贴装(SMD)设计,引脚为两端贴片式结构,适配常规PCB(印刷电路板)的回流焊工艺,安装便捷且占用空间小,适合高密度电路板布局。

四、典型应用场景

结合参数特性,该电容适用于以下场景:

  1. 工业控制设备:PLC(可编程逻辑控制器)、传感器模块、伺服驱动器等,宽温范围适应工厂车间的温度波动;
  2. 通信基础设施:基站射频模块、路由器电源滤波、光传输设备等,低ESR保障信号稳定性;
  3. 电源转换电路:DC-DC转换器输出滤波、线性电源稳压环节,50V额定电压无需并联更高电压电容,简化电路设计;
  4. 车载电子周边:车载信息娱乐系统、车身控制模块(BCM)的辅助电源滤波(注:部分型号支持AEC-Q200汽车级认证,需确认具体批次);
  5. 小型医疗设备:便携式监护仪、输液泵的电源模块滤波(宽温与低噪声符合医疗设备对稳定性的要求)。

五、性能优势总结

  1. 宽温稳定:-55℃~+125℃的工作范围,解决工业环境中温度波动带来的性能衰减问题;
  2. 低噪声高效:600mΩ低ESR,减少电源纹波与发热,提升电路整体效率;
  3. 可靠耐用:基美钽电容工艺保障,容值一致性好,耐振动(10Hz~2000Hz,2g加速度)、耐冲击(15g峰值加速度)性能优于普通电解电容;
  4. 布局灵活:小体积封装(7.3×4.3×4.3mm),适配高密度PCB设计,节省电路板空间;
  5. 中压适配:50V额定电压覆盖中高压场景,无需额外并联电容,降低电路复杂度。

六、可靠性与环境适应性

该电容符合基美工业级电容的可靠性标准:

  • 湿度适应性:可在10%~90%相对湿度(无凝露)环境下长期工作;
  • 寿命特性:在额定电压、125℃高温下,典型寿命可达2000小时以上(具体以基美官方datasheet为准);
  • 环保合规:符合RoHS、REACH等环保指令,适配全球市场需求。

备注:如需确认汽车级认证(AEC-Q200)、医疗级认证等特殊要求,需参考基美官方发布的T491系列产品详细 datasheet。

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
