CIA0805X5R475K101MT 产品概述

一、产品简介

CIA0805X5R475K101MT(品牌:HRE / 芯声)为片式多层陶瓷电容器,标称容量4.7µF,额定电压100V,容差±10%,介质材料为X5R,封装0805(公制2012)。该器件兼顾体积与耐压,适用于需要中等容量、高电压和稳定性要求的工规电子产品。

二、主要技术参数

  • 容值:4.7µF(标称)
  • 容差:±10%(K)
  • 额定电压:100V DC
  • 温度特性:X5R(工作温度范围及温度系数参照X5R规范)
  • 封装:0805(2012)
  • 品牌:HRE(芯声) (更多电气特性如耐压测试、绝缘电阻、ESR、耐电流等,请参见厂商详细数据手册)

三、性能特点

  • 高耐压:100V额定可满足工规电源和较高直流电压场景的可靠工作需求。
  • 良好体积效率:0805封装在保证耐压的同时提供较高容值,适合空间受限的PCB布局。
  • X5R介质:在-55°C至+85°C的温区内具有相对稳定的电容表现,适合去耦和能量储存用途,但非精密温度补偿型介质。
  • 工艺兼容性:适用常见无铅回流焊工艺,便于批量SMT装配。

四、典型应用

  • 开关电源的输入/输出去耦与滤波
  • 工业及车用辅助电源(须确认车规认证与温漂要求)
  • DC/DC转换器的能量缓冲与旁路
  • 高压模拟电路的耦合与旁路(不建议用于精密交流耦合场合)

五、封装与可靠性

0805封装便于自动贴装与回流焊接。X5R介质在长时间高温或高偏压条件下会有电容漂移,建议设计时保留裕量并遵循厂商关于降容、偏压和温度特性的说明。装配时请参照HRE提供的回流曲线与湿敏等级(MSL)要求,避免超出焊接温度峰值或长时间潮湿暴露。

六、选型与注意事项

  • 若电路对温度稳定性或高Q有严格要求,应考虑C0G/NP0类陶瓷或薄膜电容替代。
  • 在高偏压下X5R容值会下降(偏压效应),关键应用中请做实际偏压下的容值确认。
  • 高频纹波、电流承受能力与ESR并非X5R最优,需评估是否需并联低ESR电容(如固态电解或陶瓷小封装并联)以改善滤波性能。

七、包装与订购信息

器件型号:CIA0805X5R475K101MT,品牌:HRE(芯声)。常见供货形式为盘装或卷带,量产与小批量订单请向供应商确认最小包装单位、交期及可追溯的品质文件(RoHS、检验报告等)。

如需完整电气参数、温度/偏压特性曲线或可靠性试验数据,可提供HRE官方数据手册或样片以便做更深入的设计验证。

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
