CGA0402X7R104K350GT多层陶瓷电容器产品概述

一、产品定位与核心参数

CGA0402X7R104K350GT是芯声(HRE)针对低压小型化电路设计的多层陶瓷电容器(MLCC),主打滤波、耦合、去耦场景,兼顾容值密度与温度稳定性。核心参数如下:

  • 标称容值:100nF(标识“104”,即10×10⁴ pF)
  • 容值精度:±10%(标识“K”)
  • 额定电压:35V DC
  • 温度系数:X7R(EIA标准,-55℃~+125℃,容值变化±15%)
  • 封装形式:0402(英制,对应公制1.0mm×0.5mm×0.5mm)
  • 品牌:芯声(HRE)

二、关键性能特性

1. 宽温域稳定性

X7R介质是陶瓷电容中“容值-温度”平衡的主流选择:相比Y5V(-30℃~+85℃,容变±20%)温度范围更广,相比NPO(容变±0.05%但容值<10nF)更适配高容值需求。该产品在-55℃至+125℃内,容值波动≤±15%,满足户外设备、工业高温环境的基本稳定要求。

2. 低损耗与高频适配

1kHz测试下,损耗角正切值(tanδ)≤1%;10MHz以内仍保持低阻抗特性,适合射频前端耦合、电源线路高频滤波(如5G终端的PA模块去耦)。

3. 小体积高密度

0402封装仅1.0mm×0.5mm,比0603封装体积缩小60%,可显著降低PCB布局面积,适配智能手机、智能穿戴等小型化终端。

4. 低静态功耗

25℃下,额定电压(35V)时漏电流≤35nA(公式:0.01CV,C=100nF,V=35V),有效减少电池设备的静态耗电。

三、封装与工艺优势

HRE针对0402小封装的工艺优化,提升可靠性与一致性:

  • 无铅端电极:采用SnAgCu合金,符合RoHS2.0,焊接兼容性好(与主流无铅焊料匹配),电极与陶瓷基体结合力≥10N(拉脱力测试),回流焊后无脱落风险。
  • 精密叠层工艺:每层陶瓷介质厚度控制在10μm以内,容值一致性偏差≤±5%(批量产品),避免电路参数波动。
  • 抗潮涂层:表面涂覆疏水涂层,存储时相对湿度≤60%可保持12个月性能稳定,开封后1个月内使用无受潮风险。

四、典型应用场景

该产品因“小体积+均衡性能”,广泛覆盖以下领域:

  1. 消费电子:智能手机PMIC滤波、音频信号耦合、智能手环电源去耦;
  2. 工业自动化:PLC数字信号线路滤波、传感器接口耦合、小型电源模块去耦;
  3. 通信设备:路由器以太网接口滤波、小型基站射频子系统耦合;
  4. 小型家电:智能插座控制电路滤波、加湿器稳压辅助。

五、可靠性与合规性

HRE通过全流程可靠性测试,符合行业标准:

  • 高温寿命:125℃、35V下连续工作1000小时,容值变化≤±5%,漏电流变化≤±20%;
  • 温度循环:-55℃~+125℃循环500次(每循环2小时),无开路/短路;
  • 焊接可靠性:回流焊峰值245℃(保持10秒)后,无焊点开裂,符合IPC-J-STD-020;
  • 合规认证:RoHS2.0、REACH(SVHC限制)、IEC 60384-1(陶瓷电容通用标准)。

六、选型与使用注意事项

  1. 电压降额:建议实际工作电压≤28V(额定电压80%),避免长期过压导致容值衰减;
  2. 温度限制:禁止超过+125℃使用,-55℃以下需提前验证性能;
  3. 焊接工艺:仅支持回流焊(手工焊易损坏小封装),需遵循HRE温度曲线(240-250℃峰值,10-30秒);
  4. 存储搬运:未开封产品存于干燥环境(湿度≤60%),开封后1个月内用完,避免机械冲击(0402封装易碎)。

该产品是低压小型化电路的高性价比选择,平衡了性能、体积与成本,适配多数消费电子及工业场景的基础需求。

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
