EEEFP1V221AP 产品概述

一、产品简介

EEEFP1V221AP 是 PANASONIC(松下)推出的一款贴片型铝电解电容,标称容量 220µF,公差 ±20%,额定电压 35V。封装为 SMD,电容体直径 D=8mm,长度 L=10.2mm,适合主流开关电源滤波、总线去耦与能量缓冲等场合。

二、主要性能参数

  • 容量:220µF ±20%
  • 额定电压:35V
  • 额定纹波电流:0.85A(850mA)@100kHz
  • 等效串联电阻(ESR):0.08Ω(80mΩ)@100kHz
  • 工作温度范围:-55℃ ~ +105℃
  • 寿命:2000 小时 @105℃
  • 封装:SMD,D8 × L10.2mm(贴片圆柱形)

三、电气特性与热耗估算

在厂商给定的 100kHz 条件下,峰值纹波电流 0.85A 对应的电耗 P ≈ I_rms^2 × ESR = 0.85^2 × 0.08 ≈ 0.058W(约58mW)。该损耗将以热量形式由电容及周围 PCB 散出,实际温升受布局、铜箔面积及通风影响。容量随温度与频率下降属于铝电解的典型特性,±20% 的公差需在设计滤波/时间常数时预留裕量。

四、可靠性与寿命说明

标称寿命 2000 小时(105℃)表明在高温极限下的额定寿命。按照经验法则(每降温10℃寿命约翻倍),在 85℃ 时粗略可估为约 8000 小时,但具体数值需参考厂商寿命曲线与加速老化数据。若在更高可靠性或更长寿命场合,建议选择寿命更长(如 3000–5000h 或更高温升耐受)的产品或增大容量/并联以降低单体应力。

五、典型应用场景

  • DC-DC 开关电源输出滤波与总线去耦(100kHz 工况下表现良好)
  • 点对点供电缓冲、电源上电启动平滑
  • 工业控制、通信设备及一般电子产品的电源滤波(需注意寿命与工作温度)

六、PCB 选型与装配建议

  • 遵循厂家推荐的焊盘图与极性标注,贴片电容有极性,布局时确保极性清晰。
  • SMD 铝电解对回流焊曲线敏感,应严格按照厂商回流工艺要求,避免重复高温循环。
  • 布局时为降低温升,应在电容附近留足铜面积用于散热或在背面增加散热通孔;高纹波场合可考虑并联多个电容以分担电流与降低 ESR。
  • 机械固定与抗振:在有振动与冲击环境中,推荐采用粘附剂或锁固措施防止焊点应力集中。

七、选型要点与替代建议

选择时重点关注:纹波电流能力、ESR、工作温度与寿命。若系统有更高纹波或更长寿命要求,可考虑同厂更高额定纹波、更低 ESR 或更长寿命的型号;在空间允许下并联多个相同小容量元件可降低等效 ESR 并提升纹波承载能力。对于对可靠性极为苛刻的工业/汽车应用,建议选用符合更高温度等级与寿命规范的铝电解或固态/钽电容替代。

总结:EEEFP1V221AP 以紧凑的 SMD 封装、良好的 100kHz 纹波能力与适用的电容量,适合中等功率电源滤波与一般电子设备,但在高温、高可靠场景应注意寿命对策与散热设计。

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
