50SVPK10M — 固态聚合物电容产品概述

一、产品简介

50SVPK10M 是松下(PANASONIC)出品的一款表面贴装固态聚合物电容,额定电压为 50V,标称电容值 10µF,公差 ±20%。电容体外形为圆柱形 SMD 封装,外形尺寸为直径 D = 5mm、长度 L = 6mm(D5×L6mm),适合对体积、可靠性和低等效串联电阻(ESR)有要求的电子设备使用。

二、主要电气与机械参数

  • 容值:10 µF
  • 容差:±20%
  • 额定直流电压:50 V
  • 交流纹波电流:27.5 mA @ 120 Hz
  • 等效串联电阻(ESR):80 mΩ
  • 类型:固态聚合物(低阻抗、高稳定性)
  • 封装形式:SMD,电容体直径 5 mm,长度 6 mm
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 寿命:1000 小时 @ 125 ℃

三、关键特性与优势

  • 低 ESR:80 mΩ 的 ESR 有助于降低功率损耗与发热,适合用于去耦、滤波及稳压电路中减小纹波与提升效率。
  • 固态聚合物介质:与传统液态电解电容相比,固态聚合物具有更好的高频响应、较低等效串联电感(ESL)和更稳定的阻抗特性,长期可靠性更高且漏电流较小。
  • 小体积高密度:D5×L6mm 紧凑封装,便于在空间受限的 PCB 设计中布置多个电容以满足去耦或储能需求。
  • 宽温度范围与高温寿命:支持 -55 ℃ 至 +125 ℃ 的工作温度,1000 小时 @125 ℃ 的寿命指标适合要求较高温度耐受性的场合(需结合实际工况评估寿命)。

四、典型应用场景

  • DC-DC 转换器的输入/输出滤波与去耦
  • 模拟电路与放大器电源去耦
  • 通信设备与测量仪器的稳压与去耦电容
  • 工业控制及电源模块中作为高频旁路或局部储能单元 注意:若电路存在较大低频或高频纹波电流需求,应核算实际纹波电流并考虑并联多个电容或选用额定纹波更高的型号。

五、设计与使用建议

  • 纹波电流限制:规格给出 27.5 mA @ 120 Hz,表明单只在低频大幅纹波下承载能力有限。对于高纹波或大电流应用,应并联多只电容或采用额定纹波更高的器件。
  • 电压与温度降额:为了延长寿命与保证长期可靠性,工程实践中常对额定电压和工作温度进行适度降额处理(例如在高温或连续应力工况下考虑适当降低工作电压),具体降额策略应依据系统可靠性要求与实际工况确定。
  • 焊接与贴装:作为 SMD 器件,推荐按厂商提供的回流焊温度曲线与焊盘设计进行贴装。避免在回流和后续机械应力下产生引脚/焊点裂纹。清洗剂选择需与聚合物电容兼容。
  • 并联与布局:为减小整体 ESR/ESL 或提升纹波承受能力,可在 PCB 上并联多只同型号或不同容量/ESR 的电容。高频去耦时应将电容尽量靠近电源引脚放置,减小走线寄生。

六、可靠性与注意事项

  • 使用寿命与温度密切相关:规格的 1000 小时 @125 ℃ 是加速应力条件下的寿命指标;在更低温度或更低电压工况下实际寿命会更长。务必结合加速老化与实际工作环境评估可靠性。
  • ESR 与发热:尽管 ESR 较低,但在较大纹波电流下仍会产生热量。计算实际损耗(I^2·ESR)并估算温升,必要时改善散热或并联使用。
  • 极性与反向电压:若为有极性固态电容,应注意不施加反向电压;如电路中可能出现反向瞬态,请采取保护措施或选用双极性器件。

七、选型建议

  • 若设计关注低 ESR、高频去耦且单只容量满足系统需求,50SVPK10M 可作为体积小、性能稳定的选择。
  • 若系统纹波电流或瞬态电流较大,建议评估并联方案或选用额定纹波更高的型号;若目标应用为汽车电子或需更长寿命,应优先选取寿命更长或通过高温高加速寿命验证的型号。

总结:50SVPK10M 为松下提供的一款紧凑型固态聚合物 SMD 电容,具有低 ESR、稳定的温度特性和适合中低纹波电流的应用属性。合理的电压/温度降额与贴装工艺控制,将有助于在实际产品中获得可靠的长期性能。

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.
