CGA0201X5R105K100ET 产品概述

一、产品简介

CGA0201X5R105K100ET 是一款面向高密度表贴电路板的多层陶瓷贴片电容(MLCC),额定容量为 1 μF,公差 ±10%,额定电压 10 V,介质材质为 X5R,封装为超小型 0201。该器件由 HRE(芯声)品牌生产,适用于空间受限、对电容值和稳定性有中等要求的移动设备、便携式终端及高密度模块。

二、电气特性要点

  • 标称电容:1 μF
  • 容差:±10%(K)
  • 额定直流电压:10 V
  • 介质类型:X5R(温度系数属于中等稳定型陶瓷)
  • 高频性能:MLCC 本身具备良好自谐和低等效串联电感(ESL)特性,适合旁路、滤波与去耦应用

说明:X5R 介质在温度和直流偏压下会产生一定的容量变化,实际工作电压和温度下的有效电容需在设计阶段进行验证和必要的留量。

三、封装与机械特性

  • 封装形式:0201 表贴(超小型,适合高密度组装)
  • 机械优势:体积小、重量轻,便于在空间受限的电路板上布置大量旁路/滤波电容
  • 装配注意:0201 元件尺寸极小,要求高精度贴装与回流工艺,同时对PCB焊盘设计、锡膏印刷及定位精度有较高要求

四、典型应用场景

  • 移动终端与可穿戴设备的电源去耦与补偿
  • 高密度主板、射频模块的局部旁路与滤波
  • 电源管理 IC(PMIC)输出滤波
  • 汽车电子、工业控制中对体积与性能有折衷需求的场合(需经过可靠性验证)

五、选型建议

  • 容值与公差:1 μF ±10% 在多数去耦和滤波场合能提供良好容量储备;若对稳态容量要求更高,可选 ±5% 或积层数更高的型号
  • 电压余量:建议在实际工作电压上保留裕量,X5R 在偏压下容量会下降,若电源电压接近 10 V,应考虑更高额定电压或并联多只电容
  • 温度与频率特性:X5R 在低温时容量可能下降、在高频下表现优于高K 材料的同类品;关键电路应在目标温度与频段下进行验证

六、焊接与装配建议

  • 使用适配 0201 的锡膏印刷模板和精细贴装设备,确保锡膏量均匀与元件定位准确
  • 遵循厂家或通用 MLCC 回流曲线建议,避免过快或过高的温度梯度导致裂纹
  • 装配后避免对 PCB 局部施加过大弯曲或机械应力,0201 尺寸下机械应力更易引发微裂纹
  • 对于长时间存储或暴露在潮湿环境的器件,按需进行烘烤回潮处理并遵守管控流程

七、可靠性与测试要点

  • 常用检测项目:外观、容量与损耗角、绝缘电阻/漏电流、耐焊性(焊接热冲击)、热循环、机械振动与冲击
  • X5R 类陶瓷在长期偏压、温度循环下可能发生微量容量漂移,关键应用需做寿命试验或加冗余设计
  • 建议在样片评估阶段进行实际电压、温度与频率工况下的表征,以确认电路性能和鲁棒性

八、包装与采购说明

  • 常见包装形式为卷带(Tape & Reel),便于 SMT 贴装线自动化使用
  • 采购时请确认供应商的产品证书(RoHS / REACH 等)、批次一致性与可溯源性
  • 对于量产项目,建议提前与供应商沟通交期与库存保障策略,以降低替换风险

九、常见注意事项

  • 在高偏压场景下,测试并确认在工作电压下的实际有效电容值(DC bias 效应)
  • 对可靠性要求高的应用,必要时采用并联或选用更高额定电压/更稳定介质的方案
  • 装配、回流及后工序中均应尽量降低机械冲击与应力集中,避免裂纹导致失效

结论:CGA0201X5R105K100ET 以其微小封装和 1 μF 的容量特性,适合高密度电路中的去耦与滤波应用。设计和装配时需关注 X5R 介质的温漂和偏压特性,并采用合适的工艺与验证手段以保证长期可靠性。如需进一步电气参数曲线、封装尺寸或回流曲线,请联系 HRE(芯声)或经销商获取完整数据手册与性能报告。

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
