VT1C471M0810 产品概述

一、产品简介

VT1C471M0810 是 ROQANG(容强)系列的一款贴片铝电解电容器,额定电容为 470 µF,容差 ±20%,额定耐压 16 V,封装为 SMD,电容体尺寸 D8 × L10.2 mm。该器件专为需要大容量、紧凑封装和较高温度等级的电子设备设计,适用于开关电源输入滤波、稳压电路的旁路与储能等场合。

二、主要电气参数与特性

  • 标称电容:470 µF ±20%
  • 额定电压:16 V(极性电容,使用时注意极性)
  • 纹波电流:240 mA @ 120 Hz
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 使用寿命:2000 小时 @ 105 ℃
  • 封装/尺寸:SMD,电容体直径 8 mm,长度 10.2 mm
  • 外形与安装:贴片型,适配自动贴装与回流焊工艺

三、性能解析与示例计算

  1. 纹波处理能力:厂家给出的纹波电流为 240 mA(120 Hz),这表示器件在该频率下可长期承受的交流分量。实际电压纹波可以用 ΔV ≈ Ipp / (2π f C) 粗略估算。代入 I = 0.24 A,f = 120 Hz,C = 470 µF,可得 ΔV ≈ 0.68 V(该值为电容容抗导致的纹波,实际电路中还应考虑 ESR 带来的额外纹波)。
  2. ESR 与纹波发热:虽然此型号未在本概述中列出具体 ESR 值,但应注意 ESR 会决定纹波发热和瞬态响应,在高频开关电源场合需关注电容温升与寿命退化。
  3. 温度与寿命:标注为 2000 小时 @ 105 ℃。按照电子元件行业常见的热应力规律(温度降低可显著延长寿命),在较低工作温度下实际寿命会成倍延长,但具体倍率需参考厂方寿命加速模型或试验数据。

四、机械尺寸与封装要点

  • 体积小巧(D8×L10.2mm),适用于空间受限的移动设备、消费电子与工业控制板。
  • 贴片封装便于高速贴装生产线,但安装时需避免对顶部和侧面施加过大机械应力,粘结剂可用于增强抗振性能。
  • 顶部设有安全泄压结构,布局时应保证顶端有足够间隙,避免阻碍气体释放。

五、可靠性与寿命

  • 额定工作温度上限 105 ℃,适合中高温工作环境。
  • 2000 小时寿命指标在工业类元件中属常见水平;如需长期高可靠性(例如车规或电信设备),建议选择寿命更长或专用高可靠产品,并在设计中对电压与温度进行降额使用。
  • 禁止反向电压与频繁过压冲击,反向极性会导致电容损坏甚至泄漏或爆裂。

六、典型应用场景

  • 开关电源(SMPS)输入滤波与输出平滑
  • 线性稳压电源旁路与储能
  • 电源模块解耦、缓冲与瞬态回路
  • 工业控制、家电、消费电子的电源滤波部分(在选用前请确认寿命与环境适配)

七、PCB 布局与焊接建议

  • 严格按照厂家推荐的焊盘尺寸与回流曲线进行设计,避免过高的峰值温度与长时间高温暴露。
  • 建议在初次样机阶段通过实际回流试验验证焊接可靠性。
  • 放置时注意正负极标识,避免极性错误。对震动或冲击环境可考虑在电容基底涂胶固定。
  • 布局上,电容与热源(如大功率器件)应保持合理间距,减少温升影响寿命。

八、储存与使用注意事项

  • 建议在干燥、阴凉环境中原包装存放,避免阳光直射与潮湿环境。
  • 使用前检查外观与极性标识,发现鼓包、泄漏或破损应禁止使用。
  • 新器件在长期低温储存后可在装配前进行适当烘烤以除湿,具体条件请参考厂方说明。

九、选型建议

在系统设计时建议对 VT1C471M0810 进行电压降额与温度评估:如需更高寿命或更强纹波能力,可选用更高额定电压、容量或更大封装并关注 ESR 指标;在对体积要求严格但需高容值滤波的场合,VT1C471M0810 提供了较好的容量/尺寸比,适合作为中等功率滤波与解耦元件。最终选型请结合实际工作电压、纹波电流与预期寿命,并参考 ROQANG 提供的详细技术资料与回流焊曲线。

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.
