CGA0402X7R225K100GT 多层陶瓷电容器产品概述

一、产品基础信息

CGA0402X7R225K100GT是HRE(芯声)电子推出的多层陶瓷电容器(MLCC),型号各部分精准对应核心参数:

  • CGA:MLCC封装标识前缀;
  • 0402:英制封装尺寸(对应公制1005);
  • X7R:温度系数,代表工作温度范围-55℃~+125℃,容值变化±15%;
  • 225:容值编码(22×10⁵ pF=2.2μF);
  • K:容值精度±10%;
  • 100:额定直流电压10V;
  • GT:包装后缀(如标准16mm编带包装)。

该产品属于HRE常规系列,主打小体积高密度设计,适配消费电子、物联网等小型化场景。

二、核心参数详解

1. 容值与精度

标称容值为2.2μF,精度±10%(K级),满足多数电路对容值偏差的要求。例如电源滤波电路中,±10%的偏差不会显著影响滤波效果,兼容不同批次产品互换。

2. 额定电压与耐压

额定直流电压10V,指**-55℃~+125℃范围内长期稳定工作的最大电压**。实际使用需遵循80%电压降额原则(工作电压≤8V),避免过压导致介质击穿或老化加速。

3. 温度特性

采用X7R陶瓷介质,温度表现为:

  • 工作温度:-55℃~+125℃;
  • 容值变化率:±15%(相对于25℃基准);
    相比Y5V等介质,X7R容值受温度影响更小,适合射频耦合、工业控制等对温度敏感的电路。

4. 封装尺寸与兼容性

封装为英制0402(公制1005),物理尺寸(参考IPC标准):

  • 长度:0.40±0.02mm;
  • 宽度:0.20±0.02mm;
  • 高度:0.25±0.03mm;
    焊盘间距适配0.5mm pitch标准PCB,可与同封装元器件兼容,无需特殊Layout。

三、典型应用场景

该产品因小体积、宽温稳定、高容值密度,广泛用于:

  1. 消费电子终端:智能手机、平板的LDO输出滤波、音频耦合、射频旁路;
  2. 可穿戴设备:蓝牙耳机、智能手环的蓝牙模块电源管理;
  3. 物联网节点:温湿度/运动传感器的电源滤波与信号耦合;
  4. 工业控制:小型PLC、电机控制器的辅助电路(宽温环境稳定工作)。

四、产品优势与特点

  1. 小体积高密度:0402封装实现2.2μF/10V,比同电压钽电容体积小30%以上,节省PCB空间;
  2. 温度稳定性佳:X7R宽温范围覆盖工业级需求,容值漂移小;
  3. 高频性能优异:1kHz下ESR<10mΩ、ESL<0.5nH,适合高频电路;
  4. 环保合规:符合RoHS 2.0、REACH,不含铅镉,满足出口要求;
  5. 供货稳定:HRE成熟生产线产能充足,支持批量采购与长期供货。

五、选型与使用注意事项

  1. 电压降额:工作电压≤8V(额定电压80%),避免过压损坏;
  2. 温度限制:不得超出-55℃~+125℃,否则容值变化超15%;
  3. 焊接工艺:回流焊温度曲线符合IPC/J-STD-020(峰值240±5℃,回流时间≤10秒),避免热冲击开裂;
  4. 存储条件:未开封存于1535℃、4060%RH环境,开封后1个月内用完,防止受潮影响焊接;
  5. 极性说明:无极性MLCC,可任意方向焊接,无需区分正负极。

该产品平衡了小体积、稳定性与成本,是小型化电子设备的高性价比电容选型。

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
