CGA0402X7R104K500GT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本定位与品牌背景

CGA0402X7R104K500GT是芯声电子(HRE) 推出的通用型中高压贴片MLCC,针对高密度PCB设计优化,兼具小型化、宽温稳定性与高可靠性,广泛适配消费电子、工业控制、通信等领域的滤波、耦合、去耦需求。芯声作为国产MLCC主流品牌,其产品符合RoHS 2.0、REACH等环保标准,端电极采用无铅工艺,可替代进口同规格器件。

二、核心性能参数详解

1. 容量与精度

  • 标称容量:100nF(104)(10×10⁴ pF),满足大多数通用电路的容量需求;
  • 精度等级:±10%(K档),覆盖工业级、消费级电路的误差要求,无需额外并联/串联补偿。

2. 电压与温度特性

  • 额定电压:50V DC,可稳定工作于直流电路,低频交流电路需按峰值电压降额(建议≤40V AC峰值);
  • 温度系数:X7R介质,工作温度范围**-55℃~+125℃**,容量变化率≤±15%(典型值),适合车载、工业等宽温场景。

3. 损耗与绝缘性能

  • 损耗角正切(DF):典型值≤2.5%(1kHz/25℃),低损耗保障信号传输完整性;
  • 绝缘电阻:≥10⁹ Ω(25℃/50V/1min),高绝缘避免漏电流影响电源效率与电路稳定性。

三、封装与结构特点

1. 小型化封装

采用0402英制封装(对应公制1005),尺寸为1.0mm(长)×0.5mm(宽)×0.5mm(厚,典型值),适配智能手机、智能穿戴等高密度PCB设计,比0603封装体积缩小约60%。

2. 叠层结构与电极设计

  • 内部电极:采用镍(Ni)基材料,减少氧化风险;
  • 外部端电极:三层结构(Ni/无铅锡银铜),焊接兼容性强,回流焊后附着力≥10N(典型值),降低虚焊概率;
  • 陶瓷介质:高致密BaTiO₃基材料,耐机械应力,减少开裂风险。

四、典型应用场景

1. 消费电子领域

  • 智能手机/平板电脑:电源模块去耦电容(抑制电源纹波)、射频前端耦合电容;
  • 智能穿戴:蓝牙耳机信号滤波、智能手表传感器接口耦合。

2. 工业控制领域

  • PLC(可编程逻辑控制器):输入输出模块滤波(抑制电磁干扰);
  • 变频器:辅助电源去耦(稳定直流母线电压)。

3. 通信设备领域

  • 路由器/交换机:电源滤波网络(降低EMI);
  • 基站射频单元:中频信号耦合(匹配阻抗)。

4. 医疗电子领域

  • 便携式监护仪:电源模块滤波(保障信号纯净度)、传感器信号调理电路耦合。

五、可靠性与环境适应性

1. 环境测试认证

  • 温度循环:通过-55℃~+125℃/1000次循环测试,容量变化≤±10%;
  • 湿度耐久性:85℃/85%RH/1000小时测试,绝缘电阻≥10⁸ Ω;
  • 振动测试:10~2000Hz/2g加速度/2小时,无开路、短路故障。

2. 焊接可靠性

  • 耐回流焊:支持260℃±5℃/10秒回流焊,端电极无脱落;
  • 静电防护:人体模型(HBM)ESD≥2kV,减少组装过程中静电损伤。

六、选型与使用注意事项

1. 电压降额要求

  • 交流电路:峰值电压≤额定电压的80%(即≤40V);
  • 脉冲电路:峰值电压≤额定电压的70%(即≤35V)。

2. 焊接与储存

  • 推荐回流焊,避免手工焊接(易导致温度不均开裂);
  • 未开封产品储存于-10℃~+40℃、湿度≤60%环境,储存周期≤12个月。

3. 机械应力控制

  • 焊接后PCB弯曲度≤0.5mm,避免过度挤压器件;
  • 组装时避免用镊子直接夹取电容本体(易损伤陶瓷层)。

该产品凭借小型化、宽温稳定与高可靠性,成为替代进口同规格MLCC的高性价比选择,适配多领域通用电路需求。

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
