CGA0402X7R102K160GT 多层陶瓷电容(MLCC)产品概述

一、型号拆解与基本属性

CGA0402X7R102K160GT是HRE(芯声)推出的通用型多层陶瓷电容,型号各部分含义清晰:

  • CGA:HRE芯声MLCC产品系列标识(多层陶瓷叠层工艺);
  • 0402:英制封装尺寸(对应公制1005,即1.0mm×0.5mm),属小型化封装;
  • X7R:温度系数代码,代表工作温度范围**-55℃~+125℃**,容值变化率≤±15%;
  • 102:容值编码,10×10²pF=1000pF=1nF;
  • K:精度等级,对应**±10%**;
  • 160:额定电压编码,代表16V DC;
  • GT:后缀标识(通常为卷带包装或生产批次代码)。

基本属性汇总:

属性 详情 产品类型 多层陶瓷电容(MLCC) 品牌 HRE(芯声) 封装 0402(英制1005公制) 容值 1nF(1000pF) 精度 ±10% 额定电压 16V DC 温度系数 X7R(-55℃~+125℃,±15%容差) 环保认证 RoHS、REACH合规(无铅无卤)

二、核心性能参数与优势

2.1 容值精度与稳定性

容值1nF、±10%精度,满足大多数通用电路的匹配需求——无需超高精度(如±5%)的场景下,该精度可平衡性能与成本。X7R材料的容值稳定性远优于Y5V等低成本材料(Y5V高温下容值可能下降20%以上),避免温度波动导致的电路匹配偏差,适合对容值稳定性有基础要求的场景。

2.2 额定电压与可靠性

额定电压16V DC,适配5V、12V等低电压系统。HRE芯声对该产品做了严格可靠性测试:

  • 耐电压测试:1.5倍额定电压(24V)下保持1分钟无击穿;
  • 高温负载测试:125℃下施加10V电压,1000小时后容值变化≤±5%;
  • 振动测试:符合IPC-9701标准,抗10~2000Hz、1.5g加速度振动,适配车载等振动环境。

2.3 封装与贴装兼容性

0402封装体积小(1.0mm×0.5mm×0.5mm),可大幅提升PCB元件密度,适合智能手机、智能穿戴等小型化产品。其贴装间距符合行业标准,兼容主流SMT设备,焊盘设计与常见0402封装一致,无需额外调整PCB布局。

2.4 高频特性

MLCC的等效串联电阻(ESR)和电感(ESL)较低,1nF容值在10MHz~1GHz频段表现优异,适合射频电路的滤波、耦合(如WiFi、蓝牙模块的信号匹配)。

三、典型应用场景

3.1 消费电子终端

  • 智能手机/平板:电源模块去耦、射频电路耦合;
  • 智能穿戴(手表/手环):传感器滤波、低功耗蓝牙匹配;
  • 小型家电(智能音箱/遥控器):按键滤波、电源稳压辅助。

3.2 工业控制与车载

  • 车载系统:12V供电的显示屏、倒车雷达传感器滤波(X7R适配-40℃~85℃车载环境);
  • 工业PLC:输入输出模块信号滤波(耐振动、宽温适配工业现场);
  • 小型传感器:温湿度、压力传感器信号耦合。

3.3 通信设备

  • 小型基站:射频前端中频滤波;
  • 家用路由器:WiFi模块信号匹配;
  • 物联网终端:LoRa模块去耦。

四、选型与使用注意事项

4.1 电压降额

建议实际工作电压≤12.8V(额定电压80%),避免瞬态电压冲击(如电源上电尖峰),延长30%以上使用寿命。

4.2 温度范围

仅适用于-55℃~+125℃,极端温度(如-60℃或130℃)需换X8R/C0G温系数产品。

4.3 焊盘设计

PCB焊盘需符合IPC-7351标准,0402封装建议焊盘尺寸0.6mm×0.4mm,间距≥0.2mm,避免桥连/虚焊。

4.4 容值扩展

需更大容值(如10nF)选0603封装;需更高精度(±5%)选同系列J精度型号(如CGA0402X7R102J160GT)。

五、总结

CGA0402X7R102K160GT是HRE芯声针对通用电路推出的高性价比MLCC,兼具小体积、宽温稳定、低ESR优势,覆盖消费电子、工业控制、车载等多领域。1nF容值、±10%精度、16V额定电压的组合,平衡了性能与成本,是高密度PCB设计中滤波、耦合、去耦的优选元件。

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
