CGA0402X5R105K100GT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性

该产品为HRE(芯声) 品牌旗下的贴片多层陶瓷电容(MLCC),型号全称CGA0402X5R105K100GT,属于小体积、低电压、温度稳定型通用MLCC,适配高密度电路板设计需求,广泛应用于移动终端、可穿戴设备等轻薄化电子领域。

二、核心技术参数

产品参数严格遵循EIA(电子工业协会)及IEC 60062标准,具体如下:

  • 标称容值:1μF(型号中“105K”标识:“10”为有效数字,“5”表示10⁵次方,故10×10⁵pF=1μF);
  • 容值精度:±10%(“K”为精度代码,对应常规工业级需求);
  • 额定直流电压(VRdc):10V(型号中“100”对应10V额定电压,适配低功耗电路);
  • 温度系数:X5R(介质材料特性,兼顾温度稳定性与容值密度);
  • 工作温度范围:-55℃~+85℃;
  • 容值温度变化率:±15%(X5R典型特性,优于Y5V等低价介质);
  • 封装规格:0402(英制封装,公制对应1005,尺寸最小化)。

三、封装与尺寸规格

0402封装是电子设备轻薄化的主流小型化封装,该产品具体尺寸(公制)如下:

  • 长度(L):1.0±0.2mm;
  • 宽度(W):0.5±0.2mm;
  • 厚度(T):0.5±0.1mm;
  • 端电极结构:采用三层复合电极(镍底层+铜中间层+锡表层),兼容回流焊、波峰焊等常规贴片工艺,焊接后无虚焊、脱落风险,电气连接稳定性优异。

四、典型应用场景

因小体积、低电压、温度稳定性适中的特性,该产品广泛应用于以下领域:

  1. 移动终端:智能手机、平板电脑主板的CPU周边电源去耦、射频模块信号滤波电路;
  2. 可穿戴设备:智能手环、智能手表的传感器供电、蓝牙模块耦合电路;
  3. IoT终端:小型温湿度传感器、运动传感器节点的信号耦合与滤波;
  4. 低功耗家电:智能插座、小型智能灯泡的控制电路;
  5. 消费电子:蓝牙耳机、便携式音频设备的音频滤波电路。

五、性能优势

  1. 温度稳定性优异:X5R介质在-55℃~+85℃范围内容值变化率≤±15%,可避免温漂导致的电路性能波动,适配传感器接口等敏感场景;
  2. 小体积高密度:0402封装实现1μF容值的小型化集成,比0603封装减少30%以上电路板占用,满足设备轻薄化需求;
  3. 高可靠性长寿命:MLCC无极性、无电解液泄漏风险,额定参数下工作寿命≥10⁶小时;端电极优化设计,耐260℃回流焊热冲击,焊接后容值变化率≤±5%;
  4. 成本效益平衡:比NPO高精度介质成本降低40%左右,在保证温度稳定性的前提下,适配中低端通用电路的成本控制;
  5. 宽电压适配:10V额定电压覆盖3.3V、5V等主流低功耗供电系统,常规环境下无需额外降额设计。

六、可靠性与测试标准

产品符合IEC 60384-1(固定电容通用标准)及GB/T 2693(电子元器件应用规范),核心可靠性测试如下:

  • 温度循环测试:-55℃~+85℃循环1000次,容值变化率≤±10%,绝缘电阻≥10⁹Ω;
  • 湿度耐久性测试:85℃/85%RH环境下1000小时,容值变化率≤±10%,无外观损伤;
  • 耐电压测试:15V(额定电压1.5倍)持续1分钟,无击穿、漏电流超标;
  • 焊接热冲击测试:260℃回流焊后,端电极无脱落,容值变化率≤±5%。

七、存储与使用注意事项

  1. 存储环境:建议在温度25±5℃、湿度≤60%RH的环境中存储,超过6个月需重新除湿;
  2. 焊接工艺:回流焊温度峰值≤260℃,焊接时间≤30秒;波峰焊温度≤250℃,避免多次焊接;
  3. 降额设计:高温(>85℃)或高湿度(>85%RH)环境下,额定电压降额至8V以下;
  4. 静电防护:MLCC对静电敏感(≥200V可能击穿),操作需佩戴防静电手环,使用防静电工作台及包装。

该产品凭借稳定的性能、小型化设计及成本优势,成为低功耗电子设备通用电路的优选MLCC之一。

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
