TAJE476K025RNJ 产品概述
一、产品概述
TAJE476K025RNJ 为 AVX 品牌的钽电容，电容值 47 μF，容差 ±10%，额定电压 25 V。该型号以钽氧化物为介质，具有体积效率高、温度稳定性好等钽电容典型特性，适用于对容量与体积比有较高要求的电路。等效串联电阻（ESR）在 100 kHz 测试条件下为 900 mΩ，工作温度范围为 -55 ℃ 至 +125 ℃。
二、主要电气参数
- 电容量：47 μF，容差 ±10%
- 额定电压：25 V（极性器件，使用时注意正负极）
- ESR：900 mΩ @ 100 kHz（用于评估高频纹波抑制与发热特性）
- 工作温度：-55 ℃ ~ +125 ℃
这些参数决定了该器件在直流滤波、去耦和中低频纹波滤除场景中的适用性。
三、结构与封装
封装标识为 CASE-E-7343-43（mm），为 AVX 标准的表面贴装钽电容外形，方便自动贴装与回流焊加工。钽电容为极性器件，焊接时需注意极性方向与 PCB 标识一致。由于钽电容对焊接热脆弱，建议严格遵循厂商的回流温度曲线与预热要求。
四、典型应用场景
- 电源旁路与去耦：在模拟与数字电路电源线附近用作滤波与瞬态响应改善。
- 稳压器输入/输出滤波：为 LDO、DC-DC 转换器提供稳定的输出与抑制开关纹波。
- 储能与平滑：在空间受限的便携设备中替代体积较大的电解电容。
- 工业与汽车电子（符合温度范围要求的场合）：在宽温度范围内保持较好的容量稳定性。
五、设计与使用建议
- 极性与降额：钽电容为极性元件，避免反接。为提高可靠性，设计时建议对额定电压做适度降额（常见工程实践为 50% 左右或参照 AVX 建议），尤其在开关或浪涌条件下。
- ESR 与纹波：900 mΩ 的 ESR 在高频大电流纹波场合下会产生较高发热，应评估实际纹波电流并考虑并联低 ESR 的陶瓷电容以优化高频性能。
- 焊接与储存：遵循 AVX 的回流焊工艺与焊接曲线，避免过高峰值温度和长时间高温。储存时保持干燥、避免潮湿与受潮回流造成异常。
- 可靠性评估：在关键应用中建议进行实际电路环境下的寿命、温度循环和冲击测试。
六、可靠性与品质保证
AVX 的钽电容器件在材料选择与制程控制上具有长期积累的经验，适用于工业级应用。该型号在宽温范围内表现稳定，但具体漏电流、寿命及脉冲性能等详细参数请参考 AVX 官方 Datasheet 与样片测试数据，以便在最终设计中做出准确的匹配与风险评估。
如需进一步的电气曲线、封装尺寸图、回流焊曲线或样品测试报告，可依据型号 TAJE476K025RNJ 向 AVX 索取完整资料。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
