CGA0805X5R226M250MT(芯声HRE)贴片陶瓷电容产品概述

这款芯声(HRE)推出的CGA0805X5R226M250MT,是针对中低电压、中等容值需求设计的通用多层陶瓷贴片电容(MLCC),以稳定的温度特性和紧凑封装适配消费电子、智能家居等多场景,是市场常用的滤波/耦合选型之一。

一、产品基本身份与定位

CGA0805X5R226M250MT属于芯声通用MLCC产品线,型号编码直接对应核心参数:

  • “CGA”为芯声MLCC前缀;
  • “0805”是英制封装(公制2012,2.0mm×1.2mm);
  • “X5R”为温度系数标识;
  • “226”=22μF(22×10⁶pF);
  • “M”=±20%精度;
  • “250”=25V DC额定电压;
  • “MT”为端电极/包装后缀(具体参考芯声datasheet)。

定位为通用滤波/耦合电容,兼顾成本与性能,适合对容值稳定性有基础要求但无需超宽温度范围的电路。

二、核心参数解析

1. 电气参数

  • 容值与精度:22μF ±20%,满足大多数电源滤波、音频耦合的容值需求,±20%精度无需额外校准,适配批量生产一致性;
  • 额定电压:25V DC(直流),交流电压需按有效值降额使用(通常不超过7.5V),避免电介质击穿;
  • 温度特性:X5R(工作温度-55℃~+85℃),此范围内容值变化控制在±15%以内,比Y5V等低稳定型电容更适合温度波动场景。

2. 物理与封装参数

  • 封装尺寸:0805(2.0mm×1.2mm×1.0mm左右,具体厚度参考 datasheet),属于贴片电容中小尺寸范畴,适配高密度PCB设计;
  • 端电极:通常采用镍底层+锡表层(无铅工艺),兼容主流回流焊、波峰焊,焊接后附着力强,不易出现假焊;
  • 环保标准:符合RoHS 2.0、REACH法规,无铅无卤,满足出口及国内环保要求。

三、工艺与可靠性特性

芯声MLCC采用多层陶瓷叠层工艺,将陶瓷电介质层与镍电极交替叠压后烧结而成,相比独石电容更紧凑、容值更大:

  • 温度稳定性:X5R电介质材料的极化特性受温度影响较小,在-20℃~+60℃(典型工作温度)内,容值漂移通常不超过±5%,可稳定支撑电源滤波的纹波抑制效果;
  • 寿命可靠性:在额定电压、温度下,平均寿命可达10⁶小时以上;实际使用中若按80%电压降额(即≤20V DC),寿命可进一步提升;
  • 抗机械应力:端电极设计考虑了PCB弯曲应力,若PCB弯曲度不超过0.5%,电容无开裂风险,适合小型便携设备(如手机、智能手环)的动态环境。

四、典型应用场景

  1. 消费电子:手机/平板的DC-DC转换输出滤波(如电池供电到MCU的稳压滤波)、音频电路的信号耦合(如耳机接口隔直);
  2. 智能家居:智能音箱的电源滤波(降低纹波对音频的干扰)、智能开关的控制电路旁路电容(抑制EMI干扰);
  3. 小型家电:遥控器的按键电路滤波、电动牙刷的电机驱动稳压;
  4. 工业控制:低功耗MCU模块的电源滤波、小型温湿度传感器的信号去耦。

五、选型与替换参考

若需替换或拓展选型,需注意以下匹配点:

  • 必须匹配:封装(0805)、容值(22μF)、额定电压(≥25V);
  • 可兼容:温度系数(X5R或X7R,X7R温度范围-55℃~+125℃,若环境温度不超85℃可替换)、精度(±10%或±20%,电路允许则可提升稳定性);
  • 常见替换型号:村田GRM188R61C226M、三星CL0805X5R226M250NT、国巨CC0805KRX5RBBB226M。

六、应用注意事项

  1. 焊接工艺:无铅回流焊需遵循芯声datasheet温度曲线(峰值240℃~250℃,时间≤10秒),避免高温开裂;
  2. 降额使用:直流电压建议≤20V(80%额定值),交流电压≤7.5V(30%额定值),延长电介质寿命;
  3. 静电防护:MLCC对静电敏感(击穿电压≤1kV),操作时需佩戴防静电手环;
  4. 储存条件:未开封产品储存在25℃±5℃、湿度<60%环境,开封后12个月内使用完毕(避免端电极氧化);
  5. 机械应力:安装后避免PCB过度弯曲(弯曲度≤0.5%),防止陶瓷层开裂。

这款电容以平衡的性能和成本,成为中低端电子设备的主流MLCC选型之一,详细参数可查阅芯声官方datasheet。

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
