SS1V330M-CRE45 产品概述

一、产品简介

SS1V330M-CRE45 为贴片型铝电解电容,由品牌 ST(先科)生产,额定容量 33µF,公差 ±20%,额定电压 35V。器件采用 SMD 封装,电容体直径 D=6.3mm、长度 L=4.5mm,适用于要求体积小、容量中等且成本敏感的贴片化电路设计。典型应用包括电源滤波、去耦、旁路与能量暂存等场合。

二、主要参数(概要)

  • 容值:33µF
  • 精度:±20%
  • 额定电压:35V
  • 封装:SMD(D6.3 × L4.5 mm)
  • 工作温度:-40℃ ~ +85℃
  • 典型寿命:2000 小时 @ 85℃
  • 品牌:ST(先科)
  • 类型:贴片铝电解(极性电容,需注意正负极)

三、结构与封装特性

该系列为铝电解电容,内部采用氧化铝介质与电解液有机溶剂/固体电解质(依型号而定)。SMD 贴片形式支持自动贴装与回流焊工艺,体积小巧便于在高密度 PCB 上布局。封装尺寸 D6.3×L4.5mm 在同类产品中属于短体小直径系列,适合对高度有严格限制的模块设计。

四、性能与应用要点

  • 温度与寿命:标称寿命 2000 小时(85℃),在高温高压工作时寿命会显著下降;在较低工作温度下寿命可显著延长。设计时应考虑热源与通风散热。
  • 电压与耐压:额定 35V,电路设计中建议根据可靠性需求适当降额使用(例如在长期高温或要求高可靠性场合考虑使用更高耐压或降低实际工作电压)。
  • 极性注意:作为电解电容,具有极性,使用时必须保证正确极性连接,避免反向电压导致电容损坏或爆裂。
  • 高频与纹波:铝电解电容在低频纹波滤波与大容量能量储存方面表现良好;若需更低 ESR 或更好高频性能,可与固态电容或陶瓷电容并联使用以补充高频特性。

五、典型应用场景

  • 开关电源与线性电源的输入/输出滤波
  • DC-DC 转换器的能源缓冲与稳定输出
  • 音频放大器电源耦合与去耦
  • 工业控制、仪器仪表和消费电子中对容量/体积有折衷需求的场合

六、选型与使用建议

  • 降额使用:为延长寿命与提高可靠性,建议在高温或连续负载下按一定比例(如 70~80%)降额使用。
  • 并联补偿:若电路对低 ESR 或高频纹波要求高,建议并联低阻抗固态或多层陶瓷电容。
  • 焊接与工艺:本类 SMD 铝电解电容适用于自动贴装与回流焊,但具体回流温度曲线请参照厂方资料。避免长时间高温暴露,遵循厂商推荐的焊接曲线以防电解液受损。
  • 存储与预处理:存放时避免高温潮湿与强光直射,装配前建议检查外观有无膨胀、漏液等异常。

七、可靠性与检验要点

  • 常规检验包括容量、漏电流、等效串联电阻(ESR)及外观检查(无鼓胀、无泄漏)。
  • 由于标称寿命为 2000 小时 @ 85℃,在高温工作环境下应安排合适的寿命裕量与维护计划。
  • 关键应用(如医疗、汽车等)应评估是否需要更高温度等级或通过额外可靠性认证的器件。

八、选型提示总结

SS1V330M-CRE45 以其紧凑的 SMD 外形和 33µF/35V 的参数适合对体积和容量有平衡要求的通用电源滤波和去耦场景。设计时关注工作温度、实际电压降额、与其他电容的并联策略以及焊接工艺控制,可有效发挥其成本与尺寸优势同时保证长期可靠性。若有更严格的寿命或高温要求,建议向供应商索取更详细的电气与热模型数据,或选用更高温等级的产品。

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.
