CGA1206X5R476K100NT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性

CGA1206X5R476K100NT是HRE芯声电子推出的表面贴装多层陶瓷电容(MLCC),属于常规中容值系列产品。型号命名遵循行业通用规则:

  • CGA:HRE品牌MLCC的产品前缀;
  • 1206:英制封装代码(对应公制尺寸3.2mm×1.6mm);
  • X5R:温度特性代码;
  • 476K:容值标识(47×10⁶pF=47μF,K=±10%精度);
  • 100:额定直流电压10V;
  • NT:封装细节与生产批次标识(HRE内部定义)。
    该产品采用环保镍电极(Ni),符合RoHS 2.0及REACH标准,无铅无卤,适配现代电子制造工艺。

二、核心性能参数

三、封装与结构特点

1206封装为小型化表面贴装结构,适配常规回流焊、波峰焊工艺,核心特点:

  • 尺寸紧凑:公制3.2mm(长)×1.6mm(宽)×1.6mm(厚),重量约0.03g,适合高密度PCB布局;
  • 电极结构:多层陶瓷叠层+镍内电极+无铅外电极(锡银铜合金),焊接兼容性强;
  • 可靠性设计:陶瓷介质层均匀叠层,减少应力集中;外电极采用“镍/铜/锡”三层结构,防止氧化,延长存储周期。

四、温度特性与可靠性

X5R温度特性是该产品的核心优势,具体表现:

  • 温度范围:工作温度覆盖-55℃至+85℃,满足消费电子、工业低功耗设备的环境需求;
  • 容值稳定性:全温度范围内容值变化≤±15%,远优于Y5V等低价电容,适合滤波、耦合电路;
  • 可靠性验证:通过HRE内部及第三方测试,包括:
    • 高温负载寿命(125℃/10V,1000小时,容变≤±10%,IR≥10⁴MΩ);
    • 温度循环(-55℃~+85℃,500循环,无开裂、容变≤±10%);
    • 回流焊兼容性(峰值260℃,10秒,无电极脱落、介质开裂)。

五、典型应用场景

该产品因体积小、容值适中、稳定性好,广泛应用于:

  1. 消费电子:智能手机、平板的电源滤波(电池管理系统BMS、充电模块)、音频耦合(耳机接口、扬声器驱动);
  2. 通信终端:路由器、交换机的电源模块滤波、信号耦合;
  3. 工业控制:小型PLC、传感器模块的电源稳压、抗干扰滤波;
  4. 智能家居:智能音箱、智能门锁的低功耗电路滤波;
  5. 车载辅助电子:车载充电器、辅助显示的电源滤波(需确认应用温度≤85℃)。

六、选型与替换参考

若需替换,需匹配核心参数:

  • 同参数替换:三星CL10A476KAYNNNE、国巨CC1206KKX7RBBB476(X7R与X5R可兼容,若应用温度≤85℃)、风华MLCC1206X5R476K100;
  • 参数调整原则:需更高电压可选16V同容值(如CGA1206X5R476K160);需更大容值需换1210封装(如470μF);
  • 注意事项:替换时确认封装尺寸、电极材料(无铅)与原设计一致,避免焊接问题。

七、存储与使用注意事项

  1. 存储环境:未开封产品存于0℃~40℃、湿度≤60%环境,避免阳光直射、腐蚀性气体;开封后12个月内用完;
  2. 焊接工艺:回流焊预热150℃180℃(60120秒),升温速率≤3℃/s,峰值260℃(10~20秒);波峰焊浸锡时间≤3秒,温度≤245℃;
  3. 机械防护:贴片后避免弯折PCB,防止电容开裂;焊接后检查无电极脱落、裂纹;
  4. 静电防护:操作时佩戴静电手环,使用防静电工具,避免静电击穿。

该产品平衡了容值、体积与稳定性,是消费电子、工业控制领域的高性价比选择。

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
