AVX TAJE107K025RNJ 产品概述

一、概述

TAJE107K025RNJ 是 AVX 提供的一款高容值固体钽电容器,额定电压 25V,名义电容量 100µF,容差 ±10%。该器件工作温度范围为 -55℃ 到 +125℃,在高温和苛刻环境下仍能保持稳定性能。封装为 CASE-E-7343-43(mm),适合对体积与容量有较高要求的电源去耦与储能场合。

二、主要电气参数

  • 名称:TAJE107K025RNJ(AVX)
  • 电容量:100 µF(标称值)
  • 容差:±10%
  • 额定电压:25 V DC
  • 等效串联电阻(ESR):300 mΩ @ 100 kHz
  • 工作温度范围:-55℃ ~ +125℃
  • 封装:CASE-E-7343-43(mm)
  • 极性:有极性(固体钽电容,使用时注意正负极)

三、性能特点

  1. 高容值/高体积效率:在相对紧凑的 CASE-E-7343 封装中实现 100µF 的储能,适合对体积和容量敏感的设计。
  2. 低中频 ESR:300 mΩ(@100kHz)的 ESR 有利于减少纹波电压和功率损耗,改善去耦效果。
  3. 宽温度范围:-55℃~+125℃ 的工作温度使其能用于工业级及部分军工/航天类环境(需按具体认证确认)。
  4. 稳定性与可靠性:固体钽材料在稳定 DC 条件下具有良好的寿命特性,但对浪涌电流和反向电压较为敏感,应在系统设计中采取防护措施。

四、典型应用场景

  • 开关电源输出侧滤波与储能
  • DC-DC 转换器的输入/输出去耦
  • 微控制器及高频电路的局部供电稳定
  • 通信设备、工业控制、仪表等需要长期稳定电源的系统

五、设计与使用建议

  • 电压降额:为降低失效风险,建议在设计时考虑对额定电压的降额使用。常见做法为将工作电压控制在额定电压的 50%~80% 之间,具体降额比例应根据应用中的浪涌与冲击情况决定。
  • 防止浪涌与反向偏压:钽电容对浪涌电流和反向偏压较敏感,建议在可能出现启动浪涌或反向电压的电路中增加限流电阻、软启动电路或并联保护元件(如 TVS 或熔断保护)。
  • PCB 布局:为了获得最佳去耦效果,器件应尽量靠近电源引脚放置,走线最短并采用充足的焊盘与过孔进行热与电连接。
  • 焊接与可靠性:遵循 AVX 的焊接与回流焊工艺建议,避免过度热循环和机械应力集中,存储和装配时防潮防污染。

六、包装与标识

TAJE 系列通常按 AVX 标准出厂包装并带有完整标识,封装为 CASE-E-7343-43(mm),便于表面贴装或自动化装配。具体尺寸与焊盘推荐请参考 AVX 官方数据手册以保证匹配性。

七、选择与替代

在选型时,应综合考虑工作电压、温度、ESR、体积及可靠性需求。若电路对浪涌耐受性有更高要求,可考虑采用钽聚合物或铝电解/固态电容作为替代,并在需要时增加串联/并联配置以优化 ESR 与耐冲击能力。

结论:TAJE107K025RNJ 以其 100µF 的高容值、较低的 ESR 和宽温度范围,适合用于对体积与去耦性能要求较高的电源应用。但在设计时需注意钽电容特有的浪涌与反向电压敏感性,采取适当的降额与保护措施以保证系统长期可靠运行。若需完整电气模型、封装尺寸图和回流焊接规范,请参阅 AVX 官方数据手册。

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
