CGA0402X5R225M6R3GT 贴片MLCC产品概述

一、产品基本属性

CGA0402X5R225M6R3GT是HRE芯声推出的一款多层陶瓷贴片电容(MLCC),属于小型化高频应用的核心被动元件。其采用0402封装(英制规格,对应公制1005),介质类型为X5R,额定电压6.3V,容值2.2μF,精度±20%,适配消费电子、IoT设备等对空间紧凑、性能稳定有要求的场景。

二、核心技术参数详解

该电容的关键参数可通过型号编码直观解析,各部分含义清晰:

  • CGA:HRE芯声MLCC产品系列标识;
  • 0402:封装规格(英制),尺寸为0.04英寸×0.02英寸(1.0mm×0.5mm),适配高密度PCB布局;
  • X5R:介质材料温度特性,对应工作温度范围**-55℃~+85℃,容值变化率±15%**;
  • 225:容值编码(三位有效数字+指数),即22×10⁵pF=2.2μF;
  • M:容值精度等级,对应**±20%**(行业常见精度:J=±5%、K=±10%、M=±20%);
  • 6R3:额定直流电压,即6.3V(交流应用需按1.414倍降额);
  • GT:产品后缀,代表无铅环保、符合RoHS/REACH标准的封装版本。

补充参数:100kHz下ESR(等效串联电阻)<10mΩ,ESL(等效串联电感)<0.5nH,高频性能优异。

三、温度特性与稳定性分析

X5R介质是MLCC中容值与温度稳定性平衡的典型选择:

  • 工作温度覆盖-55℃至+85℃,满足便携式设备户外使用(如智能手环、蓝牙耳机)的环境要求;
  • 容值变化率控制在±15%以内,远优于Y5V介质(容值变化±20%~+80%),避免温度波动导致电路性能漂移;
  • 与NP0介质(容值稳定但容量小)相比,X5R可实现2.2μF中等容量,适配电源滤波、耦合等场景。

四、典型应用场景

该电容因小型化、稳定的温度特性及适中容值,广泛应用于:

  1. 消费电子终端:智能手机/平板的PMIC电源滤波、音频电路耦合;
  2. 可穿戴设备:蓝牙耳机、智能手表的传感器信号滤波、射频耦合;
  3. IoT设备:小型智能家居传感器(温湿度/ motion)的电源去耦、通信模块信号耦合;
  4. 便携式电子:移动电源、无线充电器的低噪声滤波电路。

五、品牌与可靠性优势

HRE芯声作为专业被动元件厂商,该产品具备以下可靠性:

  • 环保合规:符合RoHS 2.0、REACH指令,无铅无镉,适配全球市场;
  • 工艺可靠:高精度叠层工艺,陶瓷层厚度均匀,降低ESR/ESL,提升高频性能;
  • 焊接兼容性:适配无铅回流焊(温度曲线符合J-STD-020),焊接良率>99.5%;
  • 寿命测试:通过85℃/85%RH(1000h)、-55℃~+85℃(1000次循环)测试,容值变化<10%,满足长期可靠性要求。

六、安装与存储注意事项

为确保性能稳定,需注意以下要点:

  1. 焊接工艺:回流焊峰值温度≤245℃(时间<10s),避免过热导致陶瓷开裂;
  2. 静电防护:0402封装易受静电损伤,操作时需佩戴防静电手环、使用防静电工作台;
  3. 存储条件:常温(15℃~35℃)、干燥(湿度<60%)环境存储,开封后12个月内使用完毕;
  4. 布局建议:安装时靠近电源引脚,减少走线长度,降低寄生电感对高频性能的影响。

该产品凭借小型化、稳定特性及高可靠性,成为便携式电子、IoT设备中电源滤波与信号耦合的优选元件。

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
