CSA0603X5R475K6R3JT 产品概述

一、产品简介

CSA0603X5R475K6R3JT 为 HRE(芯声) 系列贴片多层陶瓷电容(MLCC),额定电压 6.3V,标称电容值 4.7µF,公差 ±10%,介质材料 X5R,封装 0603(1608公制)。该产品适用于对体积和性能有较高要求的便携式与消费类电子设备,兼顾高容值与小尺寸的设计需求。

二、主要规格与特性

  • 电容值:4.7µF ±10%
  • 额定电压:6.3V DC
  • 介质/温度系数:X5R(工作温度范围约 -55°C 至 +85°C,温度下电容变化受限于X5R规范)
  • 封装:0603(约 1.6mm × 0.8mm)
  • 直流偏压效应:MLCC 在施加直流电压时电容值会下降,尤其在高容值小封装时更明显,实际电路需按工作电压评估有效电容。
  • 低等效串联电阻(ESR)与良好频率特性,适合去耦与滤波应用。

三、典型应用场景

  • 数字电路去耦:微控制器、射频模块、电源芯片局部旁路
  • 电源滤波与储能:DC-DC 转换器输入/输出旁路
  • 移动终端与可穿戴设备:受限空间下的通用去耦元件
  • 工业与仪表:对体积和温漂有一定容忍的旁路场合

四、封装与 PCB 设计建议

  • 放置靠近电源引脚,减少引线长度与回流环路以降低寄生感抗。
  • 对于高电流或低噪声场合,建议并联多只电容以获得更低的 ESR/ESL。
  • 考虑直流偏压和温度影响,若工作电压接近额定值或需更稳定电容,建议采用更高额定电压或更大封装。
  • 布线时保持焊盘与过孔设计对称,避免机械应力集中,回流焊后保持良好焊接质量。

五、可靠性与工艺注意事项

  • 推荐遵循 IC厂与陶瓷电容制造商的回流焊工艺规范,避免重复高温循环与超温峰值。
  • 存储与搬运时注意防潮、防尘,贴片元件对机械冲击敏感,装配时避免弯曲基板或过多应力。
  • 可提供或索取可靠性测试报告(如温度循环、湿热、机械振动等)以满足特殊应用认证需求。

六、订购信息与型号解析

  • 型号解析示例:CSA 0603 X5R 475 K 6R3 JT
    • CSA:系列/产品线代码
    • 0603:封装尺寸
    • X5R:介质类型
    • 475:电容值代码(4.7µF)
    • K:公差 ±10%
    • 6R3:额定电压 6.3V
    • JT:包装/卷带代码(常见为卷带供货)
  • 订购时请确认批次、封装形式(卷带/散装)与所需的可靠性文件。

七、使用建议小结

  • 在设计前评估直流偏压对有效电容的影响,必要时留有裕量或选用更高额定电压/更大封装。
  • 布局时优先考虑放置位置与回流路径,保证良好去耦效果。
  • 采购买样建议进行实际环境下测试,验证温度与电压工况下的性能稳定性。

如需器件数据手册(Datasheet)、频率特性曲线、DC-bias 曲线或可靠性报告,可向供应商索取相应文档以便设计验证与长期可靠性评估。

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
