ETPF1000M5H 产品概述

一、产品简介

ETPF1000M5H 为松下(PANASONIC)系列钽电容,规格为 1000µF ±20%,额定电压 2.5V,等效串联电阻(ESR)为 5mΩ(@100kHz),工作温度范围 -55℃ 至 +105℃,SMD 封装。高容量与低 ESR 特性使其在低电压大纹波电流场合具有很好的滤波与去耦能力。

二、主要技术参数

  • 容值:1000µF
  • 精度:±20%
  • 额定电压:2.5V
  • ESR:5mΩ @ 100kHz
  • 工作温度:-55℃ ~ +105℃
  • 封装:SMD(表面贴装)
  • 品牌:PANASONIC(松下)

三、核心特性与优势

  • 低 ESR(5mΩ@100kHz):在高频开关电源和快速瞬态负载下可显著降低纹波电压和功耗。
  • 大容值/体积比:在受限 PCB 面积下提供较大的储能能力,适合低压大电流供电系统。
  • 宽温度范围:-55℃~+105℃,适应工业级应用环境。
  • SMD 可实现自动化贴装与高可靠性焊接。

四、典型应用

适用于各类需低电压高容值的电源管理场景:

  • 开关电源输出滤波(DC-DC 降压模块)
  • 电源瞬态响应缓冲与去耦(CPU/FPGA/ASIC 供电)
  • 通信设备、存储与嵌入式系统的电源后端滤波
  • 工业与商用电子设备的局部储能

五、频率与热性能提示

ESR 标注于 100kHz,表明该器件对高频纹波具有良好抑制效果。器件在工作时的损耗主要由 IRMS^2·ESR 决定,设计时应评估纹波电流与散热路径,避免长时间过高的功耗导致结温升高。

六、可靠性与选型建议

  • 极性器件,请严格遵守正负极连接,避免反向电压。
  • 推荐在实际设计中进行电压降额(如常见 20%~50% 范围,根据应用与安全余量确定),以提高长期可靠性并降低故障风险。
  • 针对大起动电流或浪涌,建议使用限流电路或串联阻抗以保护电容。

七、封装与焊接注意事项

  • 采用回流焊安装,焊接需遵循厂家推荐的回流温度曲线与时间,以避免封装应力或性能退化。
  • 贴片前应保持焊盘清洁并按推荐焊膏量和焊盘设计布局,以保证热传导和机械强度。

八、与其它电容比较(选型参考)

  • 相较于铝电解:钽电容体积更小、ESR 更低、寿命与稳定性更好,但对过压与浪涌更敏感。
  • 相较于陶瓷(MLCC):在高容值需求下更具成本与体积优势,MLCC 在高频旁路上 ESR 更低但大容量受限且可能出现压电效应导致电容随电压变化。

九、存储与使用注意

  • 存储避免潮湿、高温与强振动环境,装配前如有吸湿处理要求请按规格书执行。
  • 使用前请参考松下完整数据手册(Datasheet)获取额定纹波电流、寿命评估和焊接曲线等详细参数。

十、结论与建议

ETPF1000M5H 适合要求在 2.5V 低压平台下同时具备大容量与低 ESR 的应用场景。设计时重视电压降额、纹波电流评估与散热管理,可充分发挥其在电源滤波与瞬态缓冲方面的优势。欲获取更详细的电气特性与可靠性数据,请参照松下官方 Datasheet 或联系供应商技术支持。

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
