CGA0085X7R105K500MT 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本属性

CGA0085X7R105K500MT是HRE芯声推出的表面贴装多层陶瓷电容(MLCC),核心属性如下:

  • 封装:0805英制(对应公制2.0mm×1.25mm×0.8mm典型厚度);
  • 容值:1μF(对应容值代码“105”,即10×10⁵ pF);
  • 精度:±10%(精度代码“K”);
  • 额定电压:50V直流(DC);
  • 温度系数:X7R(工业级温度特性);
  • 环保标准:符合RoHS 2.0、REACH法规,无铅端接。

二、核心性能参数详解

1. 容值与精度

1μF容值满足大多数中低频电路的滤波、耦合需求,±10%精度覆盖消费电子、工业控制等对容量稳定性要求中等的场景;实际使用中,容量偏差会因温度、电压略有变化,但仍在允许范围内。

2. 温度特性(X7R介质)

X7R是陶瓷电容中温度稳定型介质,核心表现为:

  • 工作温度范围:-55℃ ~ +125℃;
  • 容量变化率:≤±15%(在全温度范围内);
  • 对比其他介质:比NP0(高精度)成本低30%以上,比Y5V(低成本)温度稳定性好2倍,兼顾性能与成本。

3. 电气与可靠性参数

  • 低ESR(等效串联电阻):典型值<50mΩ(1kHz下),适合电源滤波;
  • 低ESL(等效串联电感):典型值<0.5nH,减少高频干扰;
  • 额定电压降额:直流工作电压建议不超过40V(80%降额),交流有效值不超过35V(70%降额),避免电介质击穿。

三、封装与工艺特点

1. 0805封装兼容性

  • 尺寸符合IPC-7351标准,焊盘间距0.6mm,适合常规PCB贴装;
  • 支持回流焊(峰值温度260℃,持续10~30秒)、选择性波峰焊,无铅端接(Sn-Ag-Cu)满足绿色制造要求。

2. 多层陶瓷工艺

  • 内部采用镍(Ni)电极叠层,外部端接采用锡基合金,无引线设计降低寄生参数;
  • 陶瓷介质层厚度均匀,耐电压性能稳定,可承受短期过压(≤63V)。

四、典型应用场景

  1. 消费电子:智能手机电池管理系统(BMS)滤波、平板电脑音频耦合、智能穿戴设备电源旁路;
  2. 工业控制:PLC(可编程逻辑控制器)I/O接口滤波、变频器电源模块、传感器信号耦合;
  3. 汽车电子:车载中控屏电源滤波、车身控制单元(BCM)辅助电路(需确认HRE该型号是否符合AEC-Q200,常规环境-40℃~+85℃适配);
  4. 通信设备:基站电源模块、路由器/交换机信号滤波、光纤收发器耦合电路。

五、可靠性与环境适应性

  1. 焊接可靠性:经过260℃回流焊热冲击10次,端接无脱落、裂纹,焊盘润湿率≥95%;
  2. 机械可靠性:抗振动(10~2000Hz,10g加速度)符合IEC 60068-2-6,抗冲击(1500g×0.5ms)符合IEC 60068-2-27;
  3. 环境寿命:85℃×85%RH(湿热测试)1000小时后,容量变化≤±5%;额定条件下MTBF(平均无故障时间)≥10⁶小时。

六、选型与应用注意事项

  1. 温度系数匹配:若需高精度(±5%内)或高频(>100MHz),选NP0介质;若温度范围需-55℃~+150℃,选X8R;
  2. 焊盘设计:PCB焊盘尺寸建议长1.3mm、宽1.0mm,避免过大导致立碑,过小导致虚焊;
  3. 储存条件:未开封产品储存在25±5℃、40±10%RH环境,开封后12个月内使用,避免吸潮影响焊接;
  4. 并联使用:若需更大容值,可并联多个同型号电容,注意分布参数匹配。

该产品凭借X7R介质的温度稳定性、0805封装的通用性,成为中低端电子设备的主流选择,平衡了性能、成本与可靠性。

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
