CS2A470M-CRG10 产品概述

一、产品简介

CS2A470M-CRG10 为贴片型铝电解电容,由品牌 ST(先科)出品,标称容量 47µF,额定电压 100V,公差 ±20%。封装为 SMD,电容体直径 D = 10mm,长度 L = 10.5mm,适配尺寸紧凑、适用于高电压、高能量密度的电源滤波与耦合场景。工作温度范围 -40℃ 至 +105℃,在 105℃ 下额定寿命为 2000 小时。

二、主要参数

  • 容值:47µF(标称)
  • 精度:±20%
  • 额定电压:100VDC
  • 封装:SMD,尺寸 D10 × L10.5 mm
  • 工作温度:-40℃ ~ +105℃
  • 寿命:2000 hrs @ 105℃
  • 极性:铝电解电容为极性器件,需按极性安装

(注:产品实际漏电流、等效串联电阻 ESR、耐冲击电压等电参数请参阅厂方完整规格书或样品测量数据。)

三、产品特点

  • 高额定电压:100V 额定电压满足中高压电源设计要求,可在较高直流母线或开关电源输出侧使用。
  • 小型化封装:D10×L10.5mm 的贴片形态便于自动化 PCB 贴装与回流焊工艺,提高装配效率与可靠性。
  • 宽温特性与长期可靠性:-40℃ 至 +105℃ 的工作温度域以及 2000 小时高温寿命,适合工业级与消费类对温度与寿命有一定要求的场合。
  • 品牌供应:由 ST(先科)生产,适合批量采购与长期供应链对接。

四、典型应用

  • 开关电源(SMPS)输出侧滤波、能量储存与纹波抑制
  • 高压直流母线滤波与旁路
  • 功率放大器与驱动电路的能量缓冲
  • 工业控制、电源模块、电动机驱动等要求较高电压与可靠性的场景

五、安装与使用建议

  • 极性识别:铝电解电容为极性器件,安装时必须保证正负极方向正确,反向电压会导致失效或爆裂。
  • 电压余量:尽可能留出额定电压余量(按应用推荐通常不满载至额定电压),以降低温升和延长寿命。
  • 回流焊工艺:遵循厂方回流焊温度曲线与时间限制,避免超温或长时间高温导致电解质分解。若需二次焊接,应与厂方确认工艺规范。
  • PCB 布局:确保垂直于 PCB 的热传导与散热路径,避免长时间在高温热点处工作;在高纹波或大电流场合注意走大铜箔以降低寄生阻抗。
  • 储存与维修:长时间储存后可能出现容量或漏电流变化,使用前建议按规格书进行老化或测试确认。

六、可靠性与寿命说明

该器件在 105℃ 环境下可持续工作 2000 小时,表明在高温与高压下具有一定可靠性。实际寿命与工作条件(电压应力、纹波电流、环境温度)密切相关。为延长使用寿命,建议降低工作温度与电压应力、控制纹波电流,并避开长时间高温环境。

七、选型与采购建议

在选型时,应结合系统最大工作电压、纹波电流、允许温升与可靠性要求评估是否使用 100V/47µF 的规格;如需更低 ESR 或更长寿命,可咨询厂方或选用专用低阻抗/长寿命系列产品。采购时请确认完整型号 CS2A470M-CRG10、批次信息与规格书,以保障一致性与质量追溯。

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
