6SVP47M 产品概述

一、主要参数与标称性能

  • 型号:6SVP47M(PANASONIC 松下)
  • 电容值:47 µF
  • 容差:±20%
  • 额定电压:6.3 V
  • 纹波电流:55 mA @ 120 Hz
  • 等效串联电阻(ESR):70 mΩ
  • 类型:铝聚合物电容(固体电解质)
  • 外形/封装:SMD,电容体直径 D = 5 mm,长度 L = 6 mm(径向/Can 结构)
  • 工作温度:-55 ℃ ~ +105 ℃
  • 工作寿命:2000 小时 @ 105 ℃

二、产品特点

  • 低 ESR:约 70 mΩ,适合需要快速充放电与低纹波电压的去耦/滤波场合。
  • 固体聚合物电解质:比湿电解电容更稳定、漏电流小、耐振动性能好,寿命受温度影响明显但短路风险低于液体电解。
  • 小体积高容量:D5×L6mm 的紧凑尺寸适合空间受限的 SMD 设计。
  • 中等耐热与寿命:105 ℃、2000 小时的寿命适用于一般工业及消费类电子,但对长期高温应采取降额使用。

三、典型应用场景

  • DC-DC 降压/升压转换器出口输出端或输入端去耦与稳定电压
  • 微处理器/FPGA 的近端旁路与电源去耦
  • 电池供电设备的滤波与瞬态能量缓冲
  • 音频电路的电源滤波(需注意容差与容值稳定性)
  • 小功率电源模块与便携设备内部电源网络

四、设计与 PCB 布局建议

  • 靠近电源引脚放置:为最大限度降低寄生感抗与电压纹波,应将电容尽量靠近受控器件的电源引脚焊接。
  • 导热与散热:高纹波或长期高温工作时注意周围器件散热,避免把电容安放在热源正上方。
  • 焊盘与贴装:按厂方推荐的焊盘尺寸与锡膏印刷参数设计,保证良好焊接强度与热传导。
  • 并联使用:当单颗纹波能力不足或需更低 ESR 时,可并联多颗以提高纹波容忍与减少温升。

五、可靠性与老化特性

  • 高温老化:2000 hrs @105 ℃ 表明在最高温度下容量与 ESR 会随时间衰减;实际使用时建议进行加速寿命试验验证系统可靠性。
  • 失效模式:常见为容量下降与 ESR 增大,极端情况下可能出现开路或短路(固体聚合物短路概率低于液体型)。
  • 电压与温度降额:为延长寿命与可靠性,推荐在设计时对额定电压与最高温度进行适当降额。

六、储存、焊接与使用注意事项

  • 储存:避免高温高湿环境,长时间储存前请参照厂方说明进行防潮处理。
  • 回流焊:按松下推荐的回流焊曲线进行焊接,避免长时间高峰温暴露。焊接后建议进行外观与功能检测。
  • 极性与反向电压:注意电容极性(若为极性结构),应避免反向电压与瞬态过压。
  • 纹波与频率:给定的 55 mA @ 120 Hz 为低频参考值,高频下等效损耗与发热需根据 ESR 与频率特性评估。

七、选型建议与替代

  • 如果系统要求更长寿命或更高温度耐受(例如 105 ℃ 下 5000 小时以上),建议选择更高规格寿命或更大封装型号。
  • 若需更低 ESR 或更大纹波能力,可考虑并联多颗或使用更大体积的铝聚合物电容或钽/薄膜电容作为替代。
  • 选型时综合考虑电压降额、工作温度、纹波电流与预期寿命,必要时与生产厂商确认详细电气/热性能曲线与推荐参数。

简要结论:6SVP47M 为松下出品的小体积铝聚合物 SMD 电容,47 µF/6.3 V、低 ESR 70 mΩ,适合中低功率电源去耦与滤波场合;在高温或长期高纹波工况下应采取降额及并联等设计手段以保证寿命与可靠性。

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.

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
