TPSE476K035R0200 产品概述

一、简介

TPSE476K035R0200 是 AVX 公司推出的一款钽固体电解电容器,额定容量为 47 µF,容量公差 ±10%,额定直流电压 35 V。此器件属于 CASE-E(尺寸约 7.3 × 4.3 mm)封装,典型等效串联电阻(ESR)为 200 mΩ(测量条件 100 kHz),适合要求体积小、容值稳定和低阻抗特性的中高电压去耦、滤波和能量贮存应用。

二、主要参数概览

  • 容值:47 µF,公差 ±10%
  • 额定电压:35 V DC
  • 等效串联电阻(ESR):200 mΩ @ 100 kHz
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 极性:有极(钽电容,注意正负极性)
  • 品牌:AVX
  • 封装:CASE-E(约 7.3 × 4.3 mm)

三、产品特点与优势

  • 体积/容量比高:在相同体积下钽电容能提供比陶瓷或铝电解更大的稳定容值,适合空间受限但需中等容值的电路。
  • 低 ESR:200 mΩ 的 ESR 有利于降低纹波电压和功率损耗,提高电源稳定性,尤其在开关电源输出滤波和瞬态响应场合表现良好。
  • 宽温度范围:-55 ℃ 至 +125 ℃ 的工作窗口,适用于工业级及部分汽车/通信设备环境(需参照具体认证与应用边界)。
  • 容值稳定:钽固体电容在温度和频率变化下容值衰减较小,适合高精度去耦和稳定电压源设计。

四、典型应用场景

  • 开关电源输出滤波与去耦(DC-DC converter)
  • 微处理器/ASIC 的局部旁路与稳压器输入/输出滤波
  • 通信设备、电源模块、仪器仪表中的能量缓冲与滤波
  • 需要较大容量且稳定电气特性的便携或工业设备(注意电压与浪涌保护)

五、封装与机械特性

TPSE476K035R0200 采用 CASE-E 封装(约 7.343 × 4.3 mm,具体尺寸以厂方机械图为准),适合表面贴装工艺。封装提供较好的焊接可靠性与热散布,但在布局时仍需留意热应力与焊接工艺参数,遵循厂商的回流焊温度曲线以避免器件损伤。

六、设计与使用建议

  • 极性严格区分:钽电容为极性元件,必须按正确正负极连接,避免反向电压。
  • 电压降额:为提高可靠性并降低失效风险,建议按照 AVX 或行业通用建议对额定电压进行适度降额(常见做法在 50%~80% 范围内,具体请参照厂方设计指南)。
  • 抑制浪涌与突变:钽电容对浪涌电流和大幅度瞬态较为敏感,输入侧或有冲击的电路应加限流、电阻或 RC 限流网络以及适当的浪涌抑制器件。
  • 布局:去耦用途时应尽量靠近被去耦器件放置,走低阻抗、短回路路径,配合多层地平面以降低寄生电感。需要更低 ESR/ESL 时可并联多个电容分摊。
  • 温升与散热:ESR 产生的热量与环境温度共同影响器件寿命,应核算实际纹波电流产生的损耗并保证环境温升在允许范围内。

七、可靠性与环境适应

该型号的工作温度范围覆盖工业级温区,钽固体电容的固有可靠性较高,但对电压、浪涌、电流密度及焊接热有明确限制。长期可靠性评估应基于厂方寿命加速试验数据(高温负载寿命、振动、冲击、湿热等),并结合系统级冗余或保护电路以提升整机可靠性。

八、采购与替代选项

TPSE476K035R0200 适用于需要 35 V、47 µF 级别容量与中等 ESR 的场合。若需更低 ESR 或更高纹波能力,可考虑并联多个相同电容或选用专门的低 ESR 系列;若要降低极性限制,可考虑非极性陶瓷或电解替代方案。具体替代型号建议参照 AVX 官方产品选型表或联系供应商获取匹配建议。

备注:如需详细电气特性曲线、机械尺寸图、回流焊工艺参数及寿命/可靠性试验数据,请参考 AVX 官方数据手册与应用说明书。

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.
