KEMET T495X476K035ATE230 模制钽电容器产品概述

一、核心参数与型号释义

该型号为KEMET(基美)T495系列模制固体钽电容,型号各部分对应参数如下:

  • T495:基美成熟模制钽电容系列标识;
  • X476:标称容值47μF(代码规则:前两位"47"为有效数字,第三位"6"为倍率10⁶pF,即47×10⁶pF=47μF);
  • K:容值精度±10%(行业标准K级精度);
  • 035:额定直流电压35V;
  • ATE230:封装及包装后缀,对应表面贴装2917(公制)/7343(英制)封装。

核心参数汇总:

参数项 规格值 标称容值 47μF 容值精度 ±10% 额定电压 35V DC 等效串联电阻(ESR) 230mΩ(典型值@100kHz) 工作温度范围 -55℃ ~ +125℃ 封装形式 表面贴装2917/7343 结构类型 模制固体钽电容

二、封装与物理特性

2917公制封装对应英制7343,尺寸为长7.3mm×宽4.3mm(73mil×43mil),采用表面贴装(SMD)设计,兼容常规回流焊工艺。模制外壳结构相比液态钽电容具有显著优势:

  • 无漏液、干涸风险,机械稳定性强;
  • 抗振动/冲击性能优异(符合IEC 60068-2-6等振动标准);
  • 适合高密度PCB布局,可用于小型化电子设备。

三、关键性能优势解析

  1. 宽温环境适应性
    工作温度覆盖-55℃至+125℃,在极端工况(如汽车发动机舱、工业高温车间)下,容值变化率控制在±15%以内(典型值),ESR波动小于20%,满足恶劣环境应用需求。

  2. 低ESR与高频性能
    230mΩ@100kHz的典型ESR值,在同规格钽电容中属于中低水平,可有效抑制高频纹波、降低功率损耗,适合电源滤波、射频电路等对噪声敏感的场景。

  3. 高可靠性与长寿命
    模制固体电解质结构避免了液态钽电容的失效风险,KEMET制造工艺确保该型号在125℃下的平均寿命可达2000小时以上(符合AEC-Q200汽车级可靠性标准),适合对可靠性要求严格的工业/汽车领域。

  4. 电压适配性
    35V额定电压覆盖多数中低压系统(如12V/24V工业电源、汽车电子),避免过压击穿风险,同时满足部分升压电路的耐压需求。

四、典型应用场景

该型号因参数平衡,广泛应用于以下领域:

  1. 工业控制设备:PLC电源滤波模块、传感器信号调理电路,利用宽温特性适应车间高低温环境;
  2. 汽车电子:车载信息娱乐系统、车身控制单元(BCM)的电源线路滤波,符合汽车级可靠性要求;
  3. 通信设备:基站射频模块、光纤收发器的电源纹波抑制,低ESR有助于降低信号噪声;
  4. 消费电子:高端笔记本电脑、服务器主板的电源滤波,模制结构适合高密度封装。

五、品牌与合规性

KEMET作为全球被动元器件龙头,钽电容技术积累超过50年,T495系列是其核心产品线之一。该型号符合:

  • 环保标准:RoHS 2.0(无铅、无镉)、REACH;
  • 国际标准:IEC 60384-18(钽电容通用标准)、AEC-Q200(汽车级);
  • 兼容性:可与主流PCB设计软件(如Altium、Cadence)的封装库匹配,降低设计成本。

该型号凭借宽温稳定、低ESR、高可靠性等特点,成为工业、汽车、通信等领域中47μF/35V钽电容的优选方案。

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
