CGA0201X5R225K100ET 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本属性与核心规格

CGA0201X5R225K100ET是HRE(芯声电子) 推出的多层陶瓷贴片电容(MLCC),聚焦低压小体积电子设计场景。核心规格可通过型号拆解与参数明确:

  • 容值:2.2μF(型号中“225”对应22×10⁵pF=2.2μF);
  • 精度:±10%(“K”为EIA精度代码);
  • 额定电压:10V直流(“100”表示10V额定值);
  • 温度系数:X5R(符合国际EIA标准);
  • 封装:0201(英制封装,对应公制尺寸0.6mm×0.3mm×0.3mm);
  • 环保认证:符合RoHS 2.0、REACH标准(无铅无镉)。

二、关键性能参数解析

2.1 容值与精度适配性

2.2μF处于中等容量区间,既满足电源滤波对“储能密度”的需求,又避免了大容量电容的体积冗余;±10%的精度覆盖90%以上通用设计场景(如耦合、去耦、低频滤波),无需额外高精度成本。

2.2 X5R温度特性平衡

X5R是MLCC的主流温度系数之一,定义为:

  • 工作温度范围:-55℃~+85℃;
  • 容值变化率:±15%(相对于25℃基准值)。 该特性既规避了NPO(C0G)类低容量局限,又比Y5V等高容量系数更稳定,适合环境温度波动较大的便携设备(如户外智能手表)。

2.3 低压场景精准定位

10V直流额定电压明确了产品的低压应用边界,适配电池供电设备(3.7V~4.2V)、低压信号电路(音频耦合、传感器接口),不建议用于12V以上高压电路。

三、封装与工艺核心优势

3.1 0201封装的小型化价值

0201是目前最小的MLCC标准封装,体积仅为0402封装的40%,极大适配智能穿戴(手环/手表)、蓝牙耳机、微型医疗设备等“极致小型化”需求,同时兼容常规SMT贴装设备。

3.2 多层叠层工艺的性能提升

采用陶瓷介质+镍基内电极的多层叠层烧结工艺,带来两大核心优势:

  • 高容量密度:相同体积下容量是单层陶瓷电容的10~20倍;
  • 低寄生参数:1kHz下典型ESR≤50mΩ、ESL≤1nH,适合高频信号处理(如射频滤波)。

3.3 HRE工艺细节优化

  • 外电极采用“镍/锡/镍”三层结构,提升焊接附着力与抗腐蚀能力;
  • 介质材料损耗低(tanδ≤0.02,1kHz),减少信号能量损耗;
  • 内电极间距均匀,避免短路风险,提升批量一致性。

四、典型应用场景

该产品因“小体积+低压+中等容量”的组合,广泛应用于:

  1. 消费电子终端:智能手机射频滤波、音频耦合,蓝牙耳机电源去耦;
  2. 智能穿戴设备:智能手表传感器接口滤波、电池管理电路;
  3. 小型工业设备:微型PLC I/O接口滤波、低压传感器模块;
  4. 汽车电子辅助电路:座舱内USB充电接口滤波、车载蓝牙模块(需确认温度≤85℃)。

五、可靠性与环境适应性

5.1 固有可靠性指标

MLCC无极性、无电解液、无机械部件,平均无故障时间(MTBF)≥10⁶小时;该型号通过AEC-Q200基础认证,满足汽车级基础可靠性要求。

5.2 环境耐受能力

  • 湿热环境:85℃/85%RH下1000小时,容值变化≤±10%;
  • 机械应力:1mm弯曲下无失效,适配回流焊/波峰焊工艺;
  • 静电防护:符合IEC 61000-4-2,接触放电±8kV、空气放电±15kV。

六、选型与使用注意事项

6.1 选型参考

  • 高精度需求:选同封装“225J”(±5%精度);
  • 高电压需求:选同封装“225K250”(25V额定电压);
  • 宽温需求:选X7R系列(-55℃~+125℃);
  • 高频低损耗:选C0G系列(容量≤1μF)。

6.2 使用要点

  1. 焊接温度峰值≤260℃(持续≤10秒),避免陶瓷介质开裂;
  2. 生产/存储需防静电(佩戴手环、用防静电包装);
  3. 实际工作电压≤8V(额定电压80%),延长寿命;
  4. 无极性电容,无需区分正负极,但需注意交流峰值电压≤10V。

总结

CGA0201X5R225K100ET是一款高性价比的小体积MLCC,平衡了容量、温度稳定性与体积,适配消费电子、智能穿戴等低压小型化场景,是行业常用的通用选型之一。

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
