TAJE476M035RNJ 钽电容产品概述

TAJE476M035RNJ是AVX公司推出的一款表面贴装(SMD)钽电解电容器,以宽温范围、低等效串联电阻(ESR)及小型化封装为核心特点,广泛适用于工业控制、汽车电子、消费电子等领域的电源滤波、耦合及储能场景。

一、产品基本信息

  • 型号:TAJE476M035RNJ
  • 品牌:AVX(全球被动元器件龙头,钽电容技术行业领先)
  • 封装类型:表面贴装(SMD),封装规格为2917(对应公制尺寸约2.9mm×1.7mm,厚度约1.5mm,具体参数需参考官方 datasheet)
  • 包装方式:标准卷带(Reel)包装,适配自动化贴装生产线,每卷典型数量为1000/2000只

二、核心电气参数

该型号关键性能明确,满足多数通用电路设计需求:

  • 标称容值:47μF(采用3位数标识“476”,即47×10⁶pF=47μF)
  • 容值精度:±20%(工业级常规精度,覆盖多数应用的容值偏差要求)
  • 额定电压:35V DC(直流额定电压,实际工作电压需低于此值,建议留安全余量)
  • 等效串联电阻(ESR):900mΩ(典型值,测试条件为25℃、120Hz;低ESR可有效抑制纹波电压、减少功率损耗)
  • 漏电流:典型值≤0.01CV(25℃下充电2分钟后,即≤0.01×35V×47μF≈16.45μA),漏电流低是钽电容的核心优势之一

三、工作环境与可靠性

TAJE476M035RNJ具备较强的环境适应性,可靠性表现突出:

  • 工作温度范围:-55℃至+125℃(宽温设计,可适应极端环境,如工业车间高低温循环、汽车发动机舱高温场景)
  • 温度特性:容值随温度变化极小(典型温度系数约±100ppm/℃),相比铝电解电容更稳定
  • 寿命特性:在额定电压(35V)及105℃环境下,典型寿命可达1000小时以上;若降低工作温度,寿命可显著延长(如25℃下寿命超10万小时)

四、典型应用场景

结合电气参数与封装特点,该型号适用于以下场景:

  1. 电源滤波:DC-DC转换器输出滤波、线性电源滤波,低ESR可抑制纹波电压,提升电源稳定性
  2. 耦合与去耦:音频电路信号耦合、数字电路(如MCU、FPGA)电源去耦,减少信号干扰
  3. 工业控制设备:PLC模块、传感器接口电路,宽温范围适应工业环境的温度波动
  4. 汽车电子:车载音响、仪表盘电源管理(部分批次支持AEC-Q200汽车级认证)
  5. 消费电子:智能手机、平板电脑的电源管理单元(PMU),小型化封装满足高密度PCB设计需求

五、产品优势与注意事项

5.1 核心优势

  • 宽温稳定:-55℃~125℃范围内性能波动小,适合极端环境应用
  • 低损耗设计:900mΩ典型ESR降低电路功率损耗,提升系统效率
  • 小型化适配:2917封装体积紧凑,适配高密度PCB布局
  • 高可靠性:钽电容无电解液干涸问题,寿命比铝电解电容更长,漏电流低

5.2 适用注意事项

  • 极性要求:钽电容为有极性电容,必须按产品标识(如正极丝印)连接正负极,反接会导致击穿损坏
  • 电压余量:实际工作电压需低于35V,建议留20%以上余量(如≤28V),避免过压失效
  • 温度限制:不得超过最高工作温度125℃,否则容值下降、漏电流增大
  • 贴装工艺:回流焊温度需符合AVX官方规范(如峰值温度≤260℃,回流时间≤30秒),避免热应力损坏

该型号作为AVX成熟的钽电容产品,凭借稳定的性能与广泛的适用性,是众多电路设计中电源管理、滤波耦合环节的可靠选择。

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
