LZ1V471M-CRG10 产品概述

一、主要参数

  • 型号:LZ1V471M-CRG10
  • 品牌:ST (先科)
  • 类型:贴片铝电解电容(极性)
  • 容值:470 μF
  • 额定电压:35 V
  • 容量精度:±20%
  • 封装:SMD,外形尺寸 D10 × L10.5 mm(直径10 mm,长度10.5 mm)
  • 工作温度范围:-45 ℃ ~ +105 ℃
  • 额定寿命:2000 小时 @ 105 ℃
  • 其它:卷绕/湿电解结构,顶端带泄压结构(请在设计时留意通风和安全间距)

二、产品特点

  1. 高容量密度:470 μF 的电容量在直径仅 10 mm 的贴片封装中实现,适合对输出滤波和去耦有较高容量要求但空间受限的电路。
  2. 宽温度范围:-45 ℃ 至 +105 ℃ 的工作温度使其可适应工业级环境及高温运行场景。
  3. 较长寿命:2000 小时 @ 105 ℃ 的加速寿命评定体现了在高温条件下的可靠性表现,适合需一定长期稳定性的应用。
  4. 贴片化封装:SMD 形式便于自动化贴装与回流焊接,提高生产效率并减少引脚应力问题。
  5. 成本与通用性:±20% 的容量公差和 35 V 的额定电压使其在多种电源等级中具备良好兼容性,适用于中高压电源滤波与储能场景。

三、典型应用

  • 开关电源(SMPS)输出滤波与主电源旁路。
  • 工业控制与驱动电路的去耦与能量缓冲。
  • 通信设备、电源模块和电源子系统的平滑滤波。
  • 需要高温耐受能力的嵌入式设备与车规前端(在符合设计要求的前提下)。
  • 任何对体积、容量与温度稳定性有平衡要求的电子产品。

四、使用与注意事项

  1. 极性连接:本产品为极性电容,必须正确连接正负极,反接会导致漏电、鼓包或爆裂。
  2. 电压降额:建议在实际设计中避免长期在额定电压下满载运行,适当降额可有效延长寿命并提高可靠性。
  3. 焊接与回流:该器件适用于表面贴装工艺,应遵循厂方推荐的焊接曲线与最大温度要求进行回流焊接,避免过高峰值温度及长时间热暴露。
  4. 安装方向与散热:电容顶端通常含有安全泄压结构,封装顶面不得受压或被覆过紧;建议在 PCB 布局时留出足够空间以利散热与泄压。
  5. 存储与预处理:长期存放后建议在焊接前进行预烘以去除可能的吸潮(遵循厂方推荐的预烘条件)。
  6. 环境与振动:虽然为表面贴装元件,但在强振动或冲击环境中需评估机械固定与粘结方案以防脱焊或应力损伤。

五、封装与外形

该器件采用圆柱形铝壳贴片结构,直径 10 mm,长度 10.5 mm,适配常见的 SMD 自动贴装设备。顶部通常带有泄压槽或鼓包位,用于在异常压力下安全打开。底部为端面接触,需在 PCB 设计时配合对应焊盘尺寸和焊膏印刷工艺以保证良好焊接可靠性。

六、可靠性与寿命

基于厂方给定的加速寿命测试:2000 小时 @ 105 ℃。在此条件下电容器应维持可接受的电气性能衰减范围。实际使用寿命受工作温度、电压应力、纹波电流及环境条件影响,合理的降额设计与良好散热可显著延长器件寿命。

七、选型与替代建议

在选型时应确认:所需电压余量、工作温度峰值、允许的尺寸限制以及对寿命的要求。若需更高寿命或更低 ESR 的特性,应考虑更高等级或特殊系列的铝电解或固态铝电容(例如长寿命 5000 小时/105 ℃ 或固态铝电容)。如需更小封装但相同容量,则可评估其他电解或高容量钽/陶瓷方案,但需注意成本、可靠性与耐压差异。

八、结语

LZ1V471M-CRG10 是一款面向空间受限但需要中高容量滤波与高温耐受的贴片铝电解电容,兼具较高的容量密度和工业级工作温度特性。合理的电路降额与焊接、散热设计能充分发挥其稳定性与使用寿命,适用于开关电源、工业电子与各类中高压电源滤波场景。若需更详细的焊接曲线、纹波电流或等效串联电阻(ESR)等电气参数,请参考厂方完整数据手册或与供应商确认。

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
